Hence, money can be used as a tool to strengthen the national and political identity of nations. In other words, the value of the national currency can be affecting citizen’s view to the economic situation of their country and national identity. Government with the maintenance of the value of the national currency must increase the confidence of its citizens into national currency and prevents that "currency substitution phenomenon" occurred and people turn to foreign currencies. Hence, this article intends to explain the zeros elimination from the national currency and study of experience of other countries and discussion history analyzed benefits and harms of zeroes elimination from the national currency, And then to evaluate the effect or lack of effect of removing of zeros from the national currency on inflation answer the question whether it is appropriate and on time to delete three zeros from the Riyal of Iran is or not? <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=zeros%20elimination%20from%20the%20national%20currency" title="zeros elimination from the national currency">zeros elimination from the national currency</a>, <a href="https://publications.waset.org/abstracts/search?q=value%20of%20the%20national%20currency" title=" value of the national currency"> value of the national currency</a>, <a href="https://publications.waset.org/abstracts/search?q=Riyal" title=" Riyal"> Riyal</a>, <a href="https://publications.waset.org/abstracts/search?q=inflation" title=" inflation"> inflation</a>, <a href="https://publications.waset.org/abstracts/search?q=Iran" title=" Iran"> Iran</a>, <a href="https://publications.waset.org/abstracts/search?q=money" title=" money"> money</a>, <a href="https://publications.waset.org/abstracts/search?q=government" title=" government"> government</a> </p> <a href="https://publications.waset.org/abstracts/19873/the-role-of-accounting-in-the-run-added-tax-in-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19873.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">538</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8997</span> Reconnecting The Peripheral Wagons to the Euro Area Core Locomotive</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Igor%20Velickovski">Igor Velickovski</a>, <a href="https://publications.waset.org/abstracts/search?q=Aleksandar%20Stojkov"> Aleksandar Stojkov</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivana%20Rajkovic"> Ivana Rajkovic</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper investigates drivers of shock synchronization using quarterly data for 27 European countries over the period 1999-2013 and taking into account the difference between core (‘the euro area core locomotive’) and peripheral euro area and transition countries (‘the peripheral wagons’). Results from panel error-correction models suggest that core of the euro area has not been strong magnetizer of the shock convergence of periphery and transition countries since the euro inception as a result of the offsetting effects of the various factors that affected the shock convergence process.

With time, science and technology got advanced, and our society is slowly making its way to a cashless mode of transaction. But as India is still a developing country, a large part of our society still depends on transaction through cash. During times of pandemics, we came to understand that everything that we touch is not safe from microbial contamination. The Indian currency is also not an exception. The Indian currency is the modern-day medium of harmful bacterial as well as other microbial contaminations resulting in diseases in human bodies. Therefore, the need came to make the currency disinfectant to give our people a healthier lifestyle. The main focus of the study is to develop a solution that, when applied to the currency notes, will kill the persisting bacteria or microbes present in the notes. So various natural edible products were used in order to prepare the solution, which is highly effective against the presence of harmful bacteria such as E. coli and S. aureus. The antibacterial activity of these natural ingredients is not unknown to us, so extracts from those products were mixed together to form a solution which was made the Indian currency notes antibacterial for 20min approx. The solution was creating a layer on the surface of currency notes, therefore, making it antibacterial for a given duration of time, i.e., no bacterial growth was seen during the time period of 20 minutes, therefore, making it safe for the usage of human hands. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Indian%20currency" title="Indian currency">Indian currency</a>, <a href="https://publications.waset.org/abstracts/search?q=antibacterial%20property%20of%20Indian%20currency" title=" antibacterial property of Indian currency"> antibacterial property of Indian currency</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20coating" title=" surface coating"> surface coating</a>, <a href="https://publications.waset.org/abstracts/search?q=currency%20disinfectant" title=" currency disinfectant"> currency disinfectant</a> </p> <a href="https://publications.waset.org/abstracts/148518/from-edible-products-to-disinfecting-currency-notes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148518.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">127</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8995</span> The Potential of Dinar (Gold) Currency as the Main Object Transaction in Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Ilham%20Agus%20Salim">Muhammad Ilham Agus Salim</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Ali"> Mohammad Ali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this article, we have elaborated a study over the nature of Islamic financial transaction by comparing between Dinar and IDR currency in Indonesia. We have found the interesting issue among scholars and practitioners in which Dinar would be a single currency ASEAN Economic Community (AEC), then becoming motivation and added value research. The assessment among dinar volatility analysis for three years ago and IDR fluctuation as well as outlook qualitative test regarding dinar are components of analysis that weak Indonesian currency should be altered to be better coinage. The value of dinar more stable than IDR and also eligible as a currency e.g. limited quantities, easy to carry, durable, easy to saved, and has the same quality. On the other hand, the existing of IDR has defeated by inflation. The EViews program explained that Dinar at current level still fluctuate, but in the first different have fixed variant. The result of analysis describing that dinar has potential as the medium exchange, because the material of dinar is relevant and feasible since 14 century until present. Therefore, dinar should be considered to solve Indonesia crisis today. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=medium%20of%20exchange" title="medium of exchange">medium of exchange</a>, <a href="https://publications.waset.org/abstracts/search?q=dinar%20%26%20IDR%20currency" title=" dinar & IDR currency"> dinar & IDR currency</a>, <a href="https://publications.waset.org/abstracts/search?q=volatility%20analysis" title=" volatility analysis"> volatility analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=EViews%20program" title=" EViews program"> EViews program</a> </p> <a href="https://publications.waset.org/abstracts/29155/the-potential-of-dinar-gold-currency-as-the-main-object-transaction-in-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29155.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">363</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8994</span> Investigation of Compliance of the Prevailing Import Murabah'a to Sharia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aqeel%20Akhtar">Aqeel Akhtar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of prevailing modes of finance in emerging Islamic banking system is Murabah’a; a financial transaction in which cost and profit both must be recognized by buyer. Otherwise the transaction would become invalid. In this mainstream, import Murabah’a transaction is divergent in such a way that the cost is not recognized and identified due to execution of import transaction in foreign currency i.e. US Dollar and the next transaction of Murabaha’a with the client is executed in local currency. Since this transaction is executed in dual currency i.e. bank pays supplier in foreign currency and executes Murabah’a with its client in local currency and it is not allowed in according to Islamic Injunctions as mentioned in hadith narrated by Hazrat Ibn-e-Umar (May Allah be pleased with them) used to sell his camels with Dirhams and take dinars instead and vice versa. Upon revealing before the Prophet (SAW), he was advised that it must not be contingent in the agreement and the ready rate would be applied and possession of one of the consideration is compulsory. The solution in this regard is that the import Murabah’a transaction should be in single currency, however, other currency can be paid in payment at the time of payment in a very indispensable situation provided that ready rate would be applied. Moreover, some of other solutions have also been given in this regard. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=shariah%20compliance" title="shariah compliance">shariah compliance</a>, <a href="https://publications.waset.org/abstracts/search?q=import%20murabaha" title=" import murabaha"> import murabaha</a>, <a href="https://publications.waset.org/abstracts/search?q=islamic%20banking" title=" islamic banking"> islamic banking</a>, <a href="https://publications.waset.org/abstracts/search?q=product%20development" title=" product development"> product development</a> </p> <a href="https://publications.waset.org/abstracts/40148/investigation-of-compliance-of-the-prevailing-import-murabaha-to-sharia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40148.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">237</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8993</span> Design and Development of an Algorithm to Predict Fluctuations of Currency Rates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nuwan%20Kuruwitaarachchi">Nuwan Kuruwitaarachchi</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20K.%20M.%20Peiris"> M.

Political and social factors came into play making currency rate changes fluctuate rapidly. Currency rate prediction has become an important factor for larger international businesses since large amounts of money exchanged between countries. This research focuses on comparing the accuracy of mainly three models; Autoregressive Integrated Moving Average (ARIMA), Artificial Neural Networks(ANN) and Support Vector Machines(SVM). series of data import, export, USD currency exchange rate respect to LKR has been selected for training using above mentioned algorithms. After training the data set and comparing each algorithm, it was able to see that prediction in SVM performed better than other models.

For instance, the size, color, and pattern of the paper are different. With the development of modern banking services, automatic methods for paper currency recognition become important in many applications like vending machines. One of the currency recognition architecture’s phases is Feature detection and description. There are many algorithms that are used for this phase, but they still have some disadvantages. This paper proposes a feature detection algorithm, which merges the advantages given in the current SIFT and SURF algorithms, which we call, Speeded up Robust Scale-Invariant Feature Transform (SR-SIFT) algorithm. Our proposed SR-SIFT algorithm overcomes the problems of both the SIFT and SURF algorithms. The proposed algorithm aims to speed up the SIFT feature detection algorithm and keep it robust. Simulation results demonstrate that the proposed SR-SIFT algorithm decreases the average response time, especially in small and minimum number of best key points, increases the distribution of the number of best key points on the surface of the currency. Furthermore, the proposed algorithm increases the accuracy of the true best point distribution inside the currency edge than the other two algorithms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=currency%20recognition" title="currency recognition">currency recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=feature%20detection%20and%20description" title=" feature detection and description"> feature detection and description</a>, <a href="https://publications.waset.org/abstracts/search?q=SIFT%20algorithm" title=" SIFT algorithm"> SIFT algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=SURF%20algorithm" title=" SURF algorithm"> SURF algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=speeded%20up%20and%20robust%20features" title=" speeded up and robust features"> speeded up and robust features</a> </p> <a href="https://publications.waset.org/abstracts/94315/a-speeded-up-robust-scale-invariant-feature-transform-currency-recognition-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94315.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">235</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8991</span> Foreign Debt and Firm Performance: Evidence from French Non-Financial Firms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salma%20Mefteh-Wali">Salma Mefteh-Wali</a>, <a href="https://publications.waset.org/abstracts/search?q=Marie-Josephe%20Rigobert"> Marie-Josephe Rigobert</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We investigate the impact of foreign currency debt on firm performance for a sample of non-financial French firms studied over the period 2002 to 2012. As foreign currency debt is both a financing and hedging instrument against foreign exchange risk, we mobilize optimal hedging theory and capital structure theory. When we study the impact on firm value, our main results show that before and after the financial crisis of 2008, foreign debt had the same behavior as domestic debt. We find that during the crisis period, foreign debt positively affects firm value. Investors perceive foreign debt as a natural hedging instrument that is likely to reduce the costs of underinvestment, alleviate cash flow volatility, limit the costs of financial distress, and generate tax shield benefits. Also, our results show that foreign leverage negatively affects the firm performance proxied by ROA and ROE, during and after the financial crisis. However, this impact is positive in the pre-crisis period. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=foreign%20currency%20derivatives" title="foreign currency derivatives">foreign currency derivatives</a>, <a href="https://publications.waset.org/abstracts/search?q=foreign%20currency%20debt" title=" foreign currency debt"> foreign currency debt</a>, <a href="https://publications.waset.org/abstracts/search?q=foreign%20currency%20hedging" title=" foreign currency hedging"> foreign currency hedging</a>, <a href="https://publications.waset.org/abstracts/search?q=firm%20performance" title=" firm performance"> firm performance</a> </p> <a href="https://publications.waset.org/abstracts/64691/foreign-debt-and-firm-performance-evidence-from-french-non-financial-firms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64691.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">311</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8990</span> The Impact of Bitcoin and Cryptocurrency on the Development of Community</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Felib%20Ayman%20Shawky%20Salem">Felib Ayman Shawky Salem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays crypto currency has become a global phenomenon known to most people.

The high-value exchange of these digital currencies also has been a target to criminal activities. The crypto currency crimes have become a challenge for the law enforcement to analyze and to proof the evidence as criminal devices. In this paper, our focus is more on bitcoin crypto currency and the possible artifacts that can be obtained from the different type of digital wallet, which is software and browser-based application. The process memory and physical hard disk are examined with the aims of identifying and recovering potential digital evidence. The stage of data acquisition divided by three states which are the initial creation of the wallet, transaction that consists transfer and receiving a coin and the last state is after the wallet is being deleted. Findings from this study suggest that both data from software and browser type of wallet process memory is a valuable source of evidence, and many of the artifacts found in process memory are also available from the application and wallet files on the client computer storage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cryptocurrency" title="cryptocurrency">cryptocurrency</a>, <a href="https://publications.waset.org/abstracts/search?q=bitcoin" title=" bitcoin"> bitcoin</a>, <a href="https://publications.waset.org/abstracts/search?q=payment%20methods" title=" payment methods"> payment methods</a>, <a href="https://publications.waset.org/abstracts/search?q=blockchain" title=" blockchain"> blockchain</a>, <a href="https://publications.waset.org/abstracts/search?q=appropriation" title=" appropriation"> appropriation</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20retailers" title=" online retailers"> online retailers</a>, <a href="https://publications.waset.org/abstracts/search?q=TOE%20framework" title=" TOE framework"> TOE framework</a>, <a href="https://publications.waset.org/abstracts/search?q=disappropriation" title=" disappropriation"> disappropriation</a>, <a href="https://publications.waset.org/abstracts/search?q=non-appropriationBitCoin" title=" non-appropriationBitCoin"> non-appropriationBitCoin</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20protection" title=" financial protection"> financial protection</a>, <a href="https://publications.waset.org/abstracts/search?q=crypto%20currency" title=" crypto currency"> crypto currency</a>, <a href="https://publications.waset.org/abstracts/search?q=money%20laundering%20cryptocurrency" title=" money laundering cryptocurrency"> money laundering cryptocurrency</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20wallet" title=" digital wallet"> digital wallet</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20forensics" title=" digital forensics"> digital forensics</a> </p> <a href="https://publications.waset.org/abstracts/186455/the-impact-of-bitcoin-and-cryptocurrency-on-the-development-of-community" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186455.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">42</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8989</span> Predicting the Lack of GDP Growth: A Logit Model for 40 Advanced and Developing Countries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamidou%20Diallo">Hamidou Diallo</a>, <a href="https://publications.waset.org/abstracts/search?q=Marianne%20Guille"> Marianne Guille</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper identifies leading triggers of deficient episodes in terms of GDP growth based on a sample of countries at different stages of development over 1994-2017. Using logit models, we build early warning systems (EWS), and our results show important differences between developing countries (DCs) and advanced economies (AEs). For AEs, the main predictors of the probability of entering in a GDP growth deficient episode are the deterioration of external imbalances and the vulnerability of fiscal position while DCs face different challenges that need to be considered. The key indicators for them are first, the low ability to pay their debts, and second, their belonging or not to a common currency area. We also build homogeneous pools of countries inside AEs and DCs. The evolution of the proportion of AE countries in the riskiest pool is marked first, by three distinct peaks just after the high-tech bubble burst, the global financial crisis, and the European sovereign debt crisis, and second by a very low minimum level in 2006 and 2007. In contrast, the situation of DCs is characterized first by the relative stability of this proportion and then by an upward trend from 2006, that can be explained by a more unfavorable socio-political environment leading to shortcomings in the fiscal consolidation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=currency%20area" title="currency area">currency area</a>, <a href="https://publications.waset.org/abstracts/search?q=early%20warning%20system" title=" early warning system"> early warning system</a>, <a href="https://publications.waset.org/abstracts/search?q=external%20imbalances" title=" external imbalances"> external imbalances</a>, <a href="https://publications.waset.org/abstracts/search?q=fiscal%20vulnerability" title=" fiscal vulnerability"> fiscal vulnerability</a>, <a href="https://publications.waset.org/abstracts/search?q=GDP%20growth" title=" GDP growth"> GDP growth</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20debt" title=" public debt"> public debt</a> </p> <a href="https://publications.waset.org/abstracts/134058/predicting-the-lack-of-gdp-growth-a-logit-model-for-40-advanced-and-developing-countries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134058.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">126</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8988</span> E-Payments, COVID-19 Restrictions, and Currency in Circulation: Thailand and Turkey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zeliha%20Sayar">Zeliha Sayar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Central banks all over the world appear to be focusing first and foremost on retail central bank digital currency CBDC), i.e., digital cash/money. This approach is predicated on the belief that the use of cash has decreased, owing primarily to technological advancements and pandemic restrictions, and that a suitable foundation for the transition to a cashless society has been revealed. This study aims to contribute to the debate over whether digital money/CBDC can be a substitute or supplement to physical cash by examining the potential effects on cash demand. For this reason, this paper compares two emerging countries, Turkey, and Thailand, to demystify the impact of e-payment and COVID-19 restrictions on cash demand by employing fully modified ordinary least squares (FMOLS), dynamic ordinary least squares (DOLS), and the canonical cointegrating regression (CCR). The currency in circulation in two emerging countries, Turkey and Thailand, was examined in order to estimate the elasticity of different types of retail payments. The results demonstrate that real internet and mobile, cart, contactless payment, and e-money are long-term determinants of real cash demand in these two developing countries. Furthermore, with the exception of contactless payments in Turkey, there is a positive relationship between the currency in circulation and the various types of retail payments. According to findings, COVID-19 restrictions encourage the demand for cash, resulting in cash hoarding. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CCR" title="CCR">CCR</a>, <a href="https://publications.waset.org/abstracts/search?q=DOLS" title=" DOLS"> DOLS</a>, <a href="https://publications.waset.org/abstracts/search?q=e-money" title=" e-money"> e-money</a>, <a href="https://publications.waset.org/abstracts/search?q=FMOLS" title=" FMOLS"> FMOLS</a>, <a href="https://publications.waset.org/abstracts/search?q=real%20cash" title=" real cash"> real cash</a> </p> <a href="https://publications.waset.org/abstracts/150227/e-payments-covid-19-restrictions-and-currency-in-circulation-thailand-and-turkey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150227.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">105</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8987</span> A Regulatory Analysis on Legal Problems of BitCoin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fady%20Tawakol">Fady Tawakol</a> </p> <p class="card-text"><strong>Abstract:</strong></p> BitCoin is a decentralized cryptocurrency that can be used without the need of traditional central banks to accomplish any e-commerce trade. The use of such currency could facilitate new economic interactions and linkages. However, without effective and efficient regulations, cryptocurrency transactions are mostly used by criminals to commit crimes such as money laundering, theft, and blackmailing. And because law is one step behind technological developments, this paper discusses the importance of regulations and supervision for the BitCoin-system, to provide unified regulatory solutions for our digital future in the Middle East.

At the same time, this makes accounting for cryptocurrency, as cash (Currency) is not possible under IAS 7 and IAS 32, Cryptocurrency also cannot be accounted for as Financial Assets at fair value through profit or loss under IFRS 9. Therefore, this paper studies the possible means to account for Cryptocurrency, since, as of today, there is not yet an accounting standard that deals with cryptocurrency. The request to have a specific accounting standard is increasing from top accounting firms and from professional accounting bodies. This study uses a mixture of qualitative and quantitative analysis in its quest to explore the best possible way to account for cryptocurrency. Interviews and surveys were conducted targeting accounting professionals. This study highlighted the deficiencies in the current way of accounting for Cryptocurrency as intangible Assets with an indefinite life. The deficiency becomes well highlighted, as the asset will then be subject to impairment, where under GAAP, only depreciation in the value of the intangible asset is recognized. On the other hand, appreciation in the value of the asset is ignored, and this prohibits the reporting entity from showing the true value of the cryptocurrency asset. This research highlights the gap that arises due to using accounting standards that are not specific for Cryptocurrency and this study confirmed that there is an urgent need to call upon the accounting standards setters (IASB and FASB) to issue accounting standards specifically for Cryptocurrency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cryptocurrency" title="cryptocurrency">cryptocurrency</a>, <a href="https://publications.waset.org/abstracts/search?q=accounting" title=" accounting"> accounting</a>, <a href="https://publications.waset.org/abstracts/search?q=IFRS" title=" IFRS"> IFRS</a>, <a href="https://publications.waset.org/abstracts/search?q=GAAP" title=" GAAP"> GAAP</a>, <a href="https://publications.waset.org/abstracts/search?q=classification" title=" classification"> classification</a>, <a href="https://publications.waset.org/abstracts/search?q=measurement" title=" measurement"> measurement</a> </p> <a href="https://publications.waset.org/abstracts/158953/accounting-for-cryptocurrency-urgent-need-for-an-accounting-standard" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158953.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">96</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8985</span> Economic Characteristics of Bitcoin: "An Analytical Study"</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelhalem%20Shahen">Abdelhalem Shahen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The world is now experiencing a digital revolution and greatly accelerated technological developments, in addition to the transition from the economy in its traditional form to the digital economy, which has resulted in the emergence of new tools that are appropriate to those developments, and from this, this paper attempts to explore the economic characteristics of the bitcoin currency that circulated recently. Due to the many advantages that distinguish it from money in its traditional forms, which have a range of economic effects. The study found that Bitcoin is among the technological innovations, which contain a set of characteristics that are worth studying, those that make it the focus of attention, such as the digital currency, the peer-to-peer property, Lower and Faster Transaction Costs, transparency, decentralized control, privacy, and Double-Spending, as well as security and Cryptographic, and finally mining. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Digital%20Economics" title="Digital Economics">Digital Economics</a>, <a href="https://publications.waset.org/abstracts/search?q=Digital%20Currencies" title=" Digital Currencies"> Digital Currencies</a>, <a href="https://publications.waset.org/abstracts/search?q=Bitcoin" title=" Bitcoin"> Bitcoin</a>, <a href="https://publications.waset.org/abstracts/search?q=Features%20of%20Bitcoin" title=" Features of Bitcoin"> Features of Bitcoin</a> </p> <a href="https://publications.waset.org/abstracts/123868/economic-characteristics-of-bitcoin-an-analytical-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123868.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">138</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8984</span> Entropy Risk Factor Model of Exchange Rate Prediction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Darrol%20Stanley">Darrol Stanley</a>, <a href="https://publications.waset.org/abstracts/search?q=Levan%20Efremidze"> Levan Efremidze</a>, <a href="https://publications.waset.org/abstracts/search?q=Jannie%20Rossouw"> Jannie Rossouw</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We investigate the predictability of the USD/ZAR (South African Rand) exchange rate with sample entropy analytics for the period of 2004-2015.

This is a descriptive cross-sectional study designed to assess the profile of microflora contamination of the Ghanaian paper currency notes and antibiotic-resistant in the Ejura Municipality. The research was conducted in Ejura, a town in the Ejura Sekyeredumase Municipal of the Ashanti region of Ghana. 70 paper currency notes which were freshly collected from the bank, consisting of 15 pieces of GH ¢1, GH ¢2, and GH ¢5, 10 pieces of GH ¢10 and GH ¢20, and 5 pieces of GH ¢50, were randomly sampled from people by exchanging their money in usage with those freshly secured from the bank. The surfaces of each GH¢ note were gently swabbed and sent to the lab immediately in sterile Zip Bags and sealed, and tenfold serial dilution was inoculated on plate count agar (PCA), MacConkey agar (MCA), mannitol salt agar (MSA), and deoxycholate citrate agar (DCA). For bacterial identification, the study used appropriate laboratory and biochemical tests. The data was analyzed using SPSS-IBM version 20.0. It was found that 95.2 % of the 70 GH¢ notes tested positive for one or more bacterial isolates. On each GH¢ note, mean counts on PCA ranged from 3.0 cfu/ml ×105 to 4.8 cfu/ml ×105. Of 124 bacteria isolated. 36 (29.03 %), 32 (25.81%), 16 (12.90 %), 20 (16.13%), 13 (10.48 %), and 7 (5.66 %) were from GH¢1, GH¢2, GH¢10, GH¢5, GH¢20, and GH¢50, respectively. Bacterial isolates were Escherichia coli (25.81%), Staphylococcus aureus (18.55%), coagulase-negative Staphylococcus (15.32%), Klebsiella species (12.10%), Salmonella species (9.68%), Shigella species (8.06%), Pseudomonas aeruginosa (7.26%), and Proteus species (3.23%). Meat shops, commercial drivers, canteens, grocery stores, and vegetable shops contributed 25.81 %, 20.16 %, 19.35 %, 17.74 %, and 16.94 % of GH¢ notes, respectively. There was 100% resistance of the isolates to Erythromycin (ERY), and Cotrimoxazole (COT). Amikacin (AMK) was the most effective among the antibiotics as 75% of the isolates were susceptible to it. This study has demonstrated that the Ghanaian paper currency notes are heavily contaminated with potentially pathogenic bacteria that are highly resistant to the most widely used antibiotics and are a threat to public health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microflora" title="microflora">microflora</a>, <a href="https://publications.waset.org/abstracts/search?q=antibiotic%20resistance" title=" antibiotic resistance"> antibiotic resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=staphylococcus%20aureus" title=" staphylococcus aureus"> staphylococcus aureus</a>, <a href="https://publications.waset.org/abstracts/search?q=culture%20media" title=" culture media"> culture media</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-drug%20resistance" title=" multi-drug resistance"> multi-drug resistance</a> </p> <a href="https://publications.waset.org/abstracts/148795/microbial-load-prevalence-and-antibiotic-resistance-of-microflora-isolated-from-the-ghanaian-paper-currency-note-a-potential-health-threat" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148795.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">107</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8982</span> The Hidden Role of Interest Rate Risks in Carry Trades</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jingwen%20Shi">Jingwen Shi</a>, <a href="https://publications.waset.org/abstracts/search?q=Qi%20Wu"> Qi Wu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We study the role played interest rate risk in carry trade return in order to understand the forward premium puzzle. In this study, our goal is to investigate to what extent carry trade return is indeed due to compensation for risk taking and, more important, to reveal the nature of these risks. Using option data not only on exchange rates but also on interest rate swaps (swaptions), our first finding is that, besides the consensus currency risks, interest rate risks also contribute a non-negligible portion to the carry trade return. What strikes us is our second finding. We find that large downside risks of future exchange rate movements are, in fact, priced significantly in option market on interest rates. The role played by interest rate risk differs structurally from the currency risk. There is a unique premium associated with interest rate risk, though seemingly small in size, which compensates the tail risks, the left tail to be precise. On the technical front, our study relies on accurately retrieving implied distributions from currency options and interest rate swaptions simultaneously, especially the tail components of the two. For this purpose, our major modeling work is to build a new international asset pricing model where we use an orthogonal setup for pricing kernels and specify non-Gaussian dynamics in order to capture three sets of option skew accurately and consistently across currency options and interest rate swaptions, domestic and foreign, within one model. Our results open a door for studying forward premium anomaly through implied information from interest rate derivative market. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carry%20trade" title="carry trade">carry trade</a>, <a href="https://publications.waset.org/abstracts/search?q=forward%20premium%20anomaly" title=" forward premium anomaly"> forward premium anomaly</a>, <a href="https://publications.waset.org/abstracts/search?q=FX%20option" title=" FX option"> FX option</a>, <a href="https://publications.waset.org/abstracts/search?q=interest%20rate%20swaption" title=" interest rate swaption"> interest rate swaption</a>, <a href="https://publications.waset.org/abstracts/search?q=implied%20volatility%20skew" title=" implied volatility skew"> implied volatility skew</a>, <a href="https://publications.waset.org/abstracts/search?q=uncovered%20interest%20rate%20parity" title=" uncovered interest rate parity"> uncovered interest rate parity</a> </p> <a href="https://publications.waset.org/abstracts/37679/the-hidden-role-of-interest-rate-risks-in-carry-trades" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37679.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">445</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8981</span> Currency Exchange Rate Forecasts Using Quantile Regression</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuzhi%20Cai">Yuzhi Cai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we discuss a Bayesian approach to quantile autoregressive (QAR) time series model estimation and forecasting.

The results obtained show that an unequally weighted combining method performs better than other forecasting methodology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=combining%20forecasts" title="combining forecasts">combining forecasts</a>, <a href="https://publications.waset.org/abstracts/search?q=MCMC" title=" MCMC"> MCMC</a>, <a href="https://publications.waset.org/abstracts/search?q=quantile%20modelling" title=" quantile modelling"> quantile modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=quantile%20forecasting" title=" quantile forecasting"> quantile forecasting</a>, <a href="https://publications.waset.org/abstracts/search?q=predictive%20density%20functions" title=" predictive density functions"> predictive density functions</a> </p> <a href="https://publications.waset.org/abstracts/33437/estimation-and-forecasting-with-a-quantile-ar-model-for-financial-returns" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33437.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">347</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8979</span> Dynamics of Bacterial Contamination and Oral Health Risks Associated with Currency Notes and Coins Circulating in Kampala City</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Walusansa">Abdul Walusansa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, paper notes and coins were collected from general public in Kampala City where ready-to-eat food can be served, in order to survey for bacterial contamination. The total bacterial number and potentially pathogenic organisms loading on currency were tested. All isolated potential pathogens were also tested for antibiotic resistance against four most commonly prescribed antibiotics. 1. The bacterial counts on one hundred paper notes sample were ranging between 6～10918/cm cm-2,the median was 141/ cm-2, according to the data it was much higher than credit cards and Australian notes which were made of polymer. The bacterial counts on sixty coin samples were ranging between 2～380/cm-2, much less than paper notes. 2. Coliform (65.6%), E. coli (45.9%), S. aureus (41.7%), B. cereus (67.7%), Salmonella (19.8%) were isolated on one hundred paper notes. Coliform (22.4%), E. coli (5.2%), S. aureus (24.1%), B. cereus (34.5%), Salmonella (10.3%) were isolated from sixty coin samples. These results suggested a high rate of potential pathogens contamination of paper notes than coins. 3. Antibiotic resistances are commonly in most of the pathogens isolated on currency. Ampicillin resistance was found in 60%of Staphylococcus aureus isolated on currency, as well as 76.6% of E. coil and 40% of Salmonella. Erythromycin resistance was detected in 56.6% of S. aureus and in 80.0% of E. coli. All the pathogens isolated were sensitive to Norfloxacin, Salmonella and S. aureus also sensitive to Cefaclor. In this paper, we also studied the antimicrobial capability of metal coins, coins collected from different countries were tested for the ability to inhibit the growth of E. sakazakii, S. aureus, E. coli, L. monocytogenes and S. typhimurium. 1) E. sakazakii appeared very sensitive to metal coins, the second is S. aureus, but E. coli, L. monocytogenes and S. typhimurium are more resistant to these metal coin samples. 2) Coins made of Nickel-brass alloy and Copper-nickel alloy showed a better effect in anti-microbe than other metal coins, especially the ability to inhibited the growth of E. sakazakii and S. aureus, all the inhibition zones produced on nutrient agar are more than 20.6 mm. Aluminium-bronze alloy revealed weak anti-microbe activity to S. aureus and no effect to kill other pathogens. Coins made of stainless steel also can’t resist bacteria growth. 3) Surprisingly, one cent coins of USA which were made of 97.5% Zinc and 2.5% Cu showed a significant antimicrobial capability, the average inhibition zone of these five pathogens is 45.5 mm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibiotic%20sensitivity" title="antibiotic sensitivity">antibiotic sensitivity</a>, <a href="https://publications.waset.org/abstracts/search?q=bacteria" title=" bacteria"> bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=currency" title=" currency"> currency</a>, <a href="https://publications.waset.org/abstracts/search?q=coins" title=" coins"> coins</a>, <a href="https://publications.waset.org/abstracts/search?q=parasites" title=" parasites"> parasites</a> </p> <a href="https://publications.waset.org/abstracts/46820/dynamics-of-bacterial-contamination-and-oral-health-risks-associated-with-currency-notes-and-coins-circulating-in-kampala-city" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46820.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">329</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8978</span> A Context-Centric Chatbot for Cryptocurrency Using the Bidirectional Encoder Representations from Transformers Neural Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Qitao%20Xie">Qitao Xie</a>, <a href="https://publications.waset.org/abstracts/search?q=Qingquan%20Zhang"> Qingquan Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaofei%20Zhang"> Xiaofei Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Di%20Tian"> Di Tian</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruixuan%20Wen"> Ruixuan Wen</a>, <a href="https://publications.waset.org/abstracts/search?q=Ting%20Zhu"> Ting Zhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ping%20Yi"> Ping Yi</a>, <a href="https://publications.waset.org/abstracts/search?q=Xin%20Li"> Xin Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Inspired by the recent movement of digital currency, we are building a question answering system concerning the subject of cryptocurrency using Bidirectional Encoder Representations from Transformers (BERT).

More and more tourism companies accept payments in digital currency for flights, hotel reservations, transportation, and more. For travellers and tourists, using cryptocurrency as a payment method has become a way to circumvent costs and prevent risks. Understanding volatility dynamics and interdependencies between standard currency and cryptocurrency is important for appropriate financial risk management to assist policy-makers and investors in marking more informed decisions. The purpose of this paper has been to understand and explain the risk spillover effects between six major cryptocurrencies and the top ten most traded standard currencies. Using data for the daily closing price of cryptocurrencies and currency exchange rates from 7 August 2015 to 10 December 2019, with 1,133 observations. The diagonal BEKK model was used to analyze the co-volatility spillover effects between cryptocurrency returns and exchange rate returns, which are measures of how the shocks to returns in different assets affect each other’s subsequent volatility. The empirical results show there are co-volatility spillover effects between the cryptocurrency returns and GBP/USD, CNY/USD and MXN/USD exchange rate returns. Therefore, currencies (British Pound, Chinese Yuan and Mexican Peso) and cryptocurrencies (Bitcoin, Ethereum, Ripple, Tether, Litecoin and Stellar) are suitable for constructing a financial portfolio from an optimal risk management perspective and also for dynamic hedging purposes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blockchain" title="blockchain">blockchain</a>, <a href="https://publications.waset.org/abstracts/search?q=co-volatility%20effects" title=" co-volatility effects"> co-volatility effects</a>, <a href="https://publications.waset.org/abstracts/search?q=cryptocurrencies" title=" cryptocurrencies"> cryptocurrencies</a>, <a href="https://publications.waset.org/abstracts/search?q=diagonal%20BEKK%20model" title=" diagonal BEKK model"> diagonal BEKK model</a>, <a href="https://publications.waset.org/abstracts/search?q=exchange%20rates" title=" exchange rates"> exchange rates</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20spillovers" title=" risk spillovers"> risk spillovers</a> </p> <a href="https://publications.waset.org/abstracts/123511/cryptocurrency-as-a-payment-method-in-the-tourism-industry-a-comparison-of-volatility-correlation-and-portfolio-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123511.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">143</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8976</span> Currency Boards in Crisis: Experience of Baltic Countries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gordana%20Kordi%C4%87">Gordana Kordić</a>, <a href="https://publications.waset.org/abstracts/search?q=Petra%20Pali%C4%87"> Petra Palić </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The European countries that during the past two decades based their exchange rate regimes on currency board arrangement (CBA) are usually analysed from the perspective of corner solution choice’s stabilisation effects. There is an open discussion on the positive and negative background of a strict exchange rate regime choice, although it should be seen as part of the transition process towards the monetary union membership. The focus of the paper is on the Baltic countries that after two decades of a rigid exchange rate arrangement and strongly influenced by global crisis are finishing their path towards the euro zone. Besides the stabilising capacity, the CBA is highly vulnerable regime, with limited developing potential. The rigidity of the exchange rate (and monetary) system, despite the ensured credibility, do not leave enough (or any) space for the adjustment and/or active crisis management. Still, the Baltics are in a process of recovery, with fiscal consolidation measures combined with (painful and politically unpopular) measures of internal devaluation. Today, two of them (Estonia and Latvia) are members of euro zone, fulfilling their ultimate transition targets, but de facto exchanging one fixed regime with another. The paper analyses the challenges for the CBA in unstable environment since the fixed regimes rely on imported stability and are sensitive to external shocks. With limited monetary instruments, these countries were oriented to the fiscal policies and used a combination of internal devaluation and tax policy measures. Despite their rather quick recovery, our second goal is to analyse the long term influence that the measures had on the national economy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=currency%20board%20arrangement" title="currency board arrangement">currency board arrangement</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20devaluation" title=" internal devaluation"> internal devaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=exchange%20rate%20regime" title=" exchange rate regime"> exchange rate regime</a>, <a href="https://publications.waset.org/abstracts/search?q=great%20recession" title=" great recession"> great recession</a> </p> <a href="https://publications.waset.org/abstracts/13120/currency-boards-in-crisis-experience-of-baltic-countries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13120.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">262</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8975</span> Simulation of Colombian Exchange Rate to Cover the Exchange Risk Using Financial Options Like Hedge Strategy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Natalia%20M.%20Acevedo">Natalia M.

With corporate hedge, the value of the company is increased by reducing the volatility of the expected cash flow and making it possible to face a lower bankruptcy costs and financial difficulties, without sacrificing tax advantages for debt financing. With the propose to avoid exchange rate troubles over cash flows of Colombian exporting firms, this dissertation uses financial options, over exchange rate between Peso and Dollar, for realizing a financial hedge. In this study, a strategy of hedge is designed for an exporting company in Colombia with the objective of preventing fluctuations because, if the exchange rate down, the number of Colombian pesos that obtains the company by exports, is less than agreed. The exchange rate of Colombia is measured by the TRM (Representative Market Rate), representing the number of Colombian pesos for an American dollar. First, the TMR is modelled through the Geometric Brownian Motion, with this, the project price is simulated using Montecarlo simulations and finding the mean of TRM for three, six and twelve months. For financial hedging, currency options were used. The 6-month projection was covered with financial options on European-type currency with a strike price of $ 2,780.47 for each month; this value corresponds to the last value of the historical TRM. In the compensation of the options in each month, the price paid for the premium, calculated with the Black-Scholes method for currency options, was considered. Finally, with the modeling of prices and the Monte Carlo simulation, the effect of the exchange hedging with options on the exporting company was determined, this by means of the unit price estimate to which the dollars in the scenario without coverage were changed and scenario with coverage. After using the scenarios: is determinate that the TRM will have a bull trend and the exporting firm will be affected positively because they will get more pesos for each dollar. The results show that the financial options manage to reduce the exchange risk. The expected value with coverage is approximate to the expected value without coverage, but the 5% percentile with coverage is greater than without coverage. The foregoing indicates that in the worst scenarios the exporting companies will obtain better prices for the sale of the currencies if they cover. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=currency%20hedging" title="currency hedging">currency hedging</a>, <a href="https://publications.waset.org/abstracts/search?q=futures" title=" futures"> futures</a>, <a href="https://publications.waset.org/abstracts/search?q=geometric%20Brownian%20motion" title=" geometric Brownian motion"> geometric Brownian motion</a>, <a href="https://publications.waset.org/abstracts/search?q=options" title=" options"> options</a> </p> <a href="https://publications.waset.org/abstracts/93475/simulation-of-colombian-exchange-rate-to-cover-the-exchange-risk-using-financial-options-like-hedge-strategy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93475.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">130</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8974</span> The 'Currency' of Dolus Eventualis Considered during Sentencing for Murder</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reuben%20Govender">Reuben Govender</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Culpability is an essential element for an accused to be held liable for a crime. The mental element or mens rea determines blameworthiness of an accused on a charge of killing a person. The mens rea required for a conviction of murder is intent while culpable homicide requires negligence. Central to blameworthiness in mens rea is individual freedom and voluntariness. The test for intent is subjective and objective for negligence. This paper presents a review of dolus eventualis in the context of murder trials and from a South African perspective. This paper poses a central questions namely, is dolus eventualis a ‘weaker currency’ during sentencing for murder? This paper attempts to answer this question by reviewing the concept of dolus eventualis, the test in judicial application, a review of decided South African cases in its application, its incorrect application and finally, considerations for its correct application. Lastly, the ‘weight’ of a dolus eventualis conviction in terms of sentencing will be reviewed to support the central question which is answered in the negative. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dolus%20eventualis" title="dolus eventualis">dolus eventualis</a>, <a href="https://publications.waset.org/abstracts/search?q=dolus%20indeterminatus" title=" dolus indeterminatus"> dolus indeterminatus</a>, <a href="https://publications.waset.org/abstracts/search?q=dolus%20generalis" title=" dolus generalis"> dolus generalis</a>, <a href="https://publications.waset.org/abstracts/search?q=mens%20rea" title=" mens rea"> mens rea</a> </p> <a href="https://publications.waset.org/abstracts/67734/the-currency-of-dolus-eventualis-considered-during-sentencing-for-murder" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67734.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">234</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8973</span> Impact of the Currency Devaluation on Contractors in Egypt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mariam%20Zahwy">Mariam Zahwy</a>, <a href="https://publications.waset.org/abstracts/search?q=Waleed%20El%20Nemr"> Waleed El Nemr</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20Samer%20Ezeldin"> A.

Studies assessing this influence are scarce, though. The impact of devaluation on contractors is measured in this study using empirical data. The difficulties contractors have as a result of rising import material costs, limited financing alternatives, and inflationary pressures are also determined by analyzing survey responses from contractors and industry experts. The approaches contractors utilize to lessen the impact of devaluation are also examined in the research. The survey results show how currency depreciation directly affects contractors in the Egyptian construction industry in terms of financial consequences. Inflationary pressures, fewer financing alternatives, and rising expenses have all affected contractors. To minimize losses, contractors have, nonetheless, put a number of tactics into practice. These findings highlight the importance of understanding and managing the impact of devaluation on the construction industry to ensure its resilience and development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=construction" title="construction">construction</a>, <a href="https://publications.waset.org/abstracts/search?q=devaluation" title=" devaluation"> devaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=contractors" title=" contractors"> contractors</a>, <a href="https://publications.waset.org/abstracts/search?q=material%20costs" title=" material costs"> material costs</a>, <a href="https://publications.waset.org/abstracts/search?q=inflationary%20pressures" title=" inflationary pressures"> inflationary pressures</a>, <a href="https://publications.waset.org/abstracts/search?q=empirical%20data" title=" empirical data"> empirical data</a>, <a href="https://publications.waset.org/abstracts/search?q=quantitative%20research" title=" quantitative research"> quantitative research</a> </p> <a href="https://publications.waset.org/abstracts/192557/impact-of-the-currency-devaluation-on-contractors-in-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192557.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">21</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8972</span> Forecasting the Fluctuation of Currency Exchange Rate Using Random Forest</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lule%20Basha">Lule Basha</a>, <a href="https://publications.waset.org/abstracts/search?q=Eralda%20Gjika"> Eralda Gjika</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The exchange rate is one of the most important economic variables, especially for a small, open economy such as Albania. Its effect is noticeable in one country's competitiveness, trade and current account, inflation, wages, domestic economic activity, and bank stability. This study investigates the fluctuation of Albania’s exchange rates using monthly average foreign currency, Euro (Eur) to Albanian Lek (ALL) exchange rate with a time span from January 2008 to June 2021, and the macroeconomic factors that have a significant effect on the exchange rate. Initially, the Random Forest Regression algorithm is constructed to understand the impact of economic variables on the behavior of monthly average foreign currencies exchange rates. Then the forecast of macro-economic indicators for 12 months was performed using time series models. The predicted values received are placed in the random forest model in order to obtain the average monthly forecast of the Euro to Albanian Lek (ALL) exchange rate for the period July 2021 to June 2022. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=exchange%20rate" title="exchange rate">exchange rate</a>, <a href="https://publications.waset.org/abstracts/search?q=random%20forest" title=" random forest"> random forest</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20series" title=" time series"> time series</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=prediction" title=" prediction"> prediction</a> </p> <a href="https://publications.waset.org/abstracts/145158/forecasting-the-fluctuation-of-currency-exchange-rate-using-random-forest" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145158.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">104</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8971</span> Determination Optimum Strike Price of FX Option Call Spread with USD/IDR Volatility and Garman–Kohlhagen Model Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bangkit%20Adhi%20Nugraha">Bangkit Adhi Nugraha</a>, <a href="https://publications.waset.org/abstracts/search?q=Bambang%20Suripto"> Bambang Suripto </a> </p> <p class="card-text"><strong>Abstract:</strong></p> On September 2016 Bank Indonesia (BI) release regulation no.18/18/PBI/2016 that permit bank clients for using the FX option call spread USD/IDR. Basically, this product is a combination between clients buy FX call option (pay premium) and sell FX call option (receive premium) to protect against currency depreciation while also capping the potential upside with cheap premium cost. BI classifies this product as a structured product. The structured product is combination at least two financial instruments, either derivative or non-derivative instruments. The call spread is the first structured product against IDR permitted by BI since 2009 as response the demand increase from Indonesia firms on FX hedging through derivative for protecting market risk their foreign currency asset or liability. The composition of hedging products on Indonesian FX market increase from 35% on 2015 to 40% on 2016, the majority on swap product (FX forward, FX swap, cross currency swap). Swap is formulated by interest rate difference of the two currency pairs. The cost of swap product is 7% for USD/IDR with one year USD/IDR volatility 13%. That cost level makes swap products seem expensive for hedging buyers. Because call spread cost (around 1.5-3%) cheaper than swap, the most Indonesian firms are using NDF FX call spread USD/IDR on offshore with outstanding amount around 10 billion USD. The cheaper cost of call spread is the main advantage for hedging buyers. The problem arises because BI regulation requires the call spread buyer doing the dynamic hedging. That means, if call spread buyer choose strike price 1 and strike price 2 and volatility USD/IDR exchange rate surpass strike price 2, then the call spread buyer must buy another call spread with strike price 1’ (strike price 1’ = strike price 2) and strike price 2’ (strike price 2’ > strike price 1‘). It could make the premium cost of call spread doubled or even more and dismiss the purpose of hedging buyer to find the cheapest hedging cost. It is very crucial for the buyer to choose best optimum strike price before entering into the transaction. To help hedging buyer find the optimum strike price and avoid expensive multiple premium cost, we observe ten years 2005-2015 historical data of USD/IDR volatility to be compared with the price movement of the call spread USD/IDR using Garman–Kohlhagen Model (as a common formula on FX option pricing). We use statistical tools to analysis data correlation, understand nature of call spread price movement over ten years, and determine factors affecting price movement. We select some range of strike price and tenor and calculate the probability of dynamic hedging to occur and how much it’s cost. We found USD/IDR currency pairs is too uncertain and make dynamic hedging riskier and more expensive. We validated this result using one year data and shown small RMS. The study result could be used to understand nature of FX call spread and determine optimum strike price for hedging plan. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=FX%20call%20spread%20USD%2FIDR" title="FX call spread USD/IDR">FX call spread USD/IDR</a>, <a href="https://publications.waset.org/abstracts/search?q=USD%2FIDR%20volatility%20statistical%20analysis" title=" USD/IDR volatility statistical analysis"> USD/IDR volatility statistical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Garman%E2%80%93Kohlhagen%20Model%20on%20FX%20Option%20USD%2FIDR" title=" Garman–Kohlhagen Model on FX Option USD/IDR"> Garman–Kohlhagen Model on FX Option USD/IDR</a>, <a href="https://publications.waset.org/abstracts/search?q=Bank%20Indonesia%20Regulation%20no.18%2F18%2FPBI%2F2016" title=" Bank Indonesia Regulation no.18/18/PBI/2016"> Bank Indonesia Regulation no.18/18/PBI/2016</a> </p> <a href="https://publications.waset.org/abstracts/65033/determination-optimum-strike-price-of-fx-option-call-spread-with-usdidr-volatility-and-garman-kohlhagen-model-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65033.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">380</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8970</span> Masked Candlestick Model: A Pre-Trained Model for Trading Prediction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ling%20Qi">Ling Qi</a>, <a href="https://publications.waset.org/abstracts/search?q=Matloob%20Khushi"> Matloob Khushi</a>, <a href="https://publications.waset.org/abstracts/search?q=Josiah%20Poon"> Josiah Poon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper introduces a pre-trained Masked Candlestick Model (MCM) for trading time-series data. The pre-trained model is based on three core designs. First, we convert trading price data at each data point as a set of normalized elements and produce embeddings of each element. Second, we generate a masked sequence of such embedded elements as inputs for self-supervised learning. Third, we use the encoder mechanism from the transformer to train the inputs. The masked model learns the contextual relations among the sequence of embedded elements, which can aid downstream classification tasks. To evaluate the performance of the pre-trained model, we fine-tune MCM for three different downstream classification tasks to predict future price trends. The fine-tuned models achieved better accuracy rates for all three tasks than the baseline models. To better analyze the effectiveness of MCM, we test the same architecture for three currency pairs, namely EUR/GBP, AUD/USD, and EUR/JPY. The experimentation results demonstrate MCM’s effectiveness on all three currency pairs and indicate the MCM’s capability for signal extraction from trading data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=masked%20language%20model" title="masked language model">masked language model</a>, <a href="https://publications.waset.org/abstracts/search?q=transformer" title=" transformer"> transformer</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20series%20prediction" title=" time series prediction"> time series prediction</a>, <a href="https://publications.waset.org/abstracts/search?q=trading%20prediction" title=" trading prediction"> trading prediction</a>, <a href="https://publications.waset.org/abstracts/search?q=embedding" title=" embedding"> embedding</a>, <a href="https://publications.waset.org/abstracts/search?q=transfer%20learning" title=" transfer learning"> transfer learning</a>, <a href="https://publications.waset.org/abstracts/search?q=self-supervised%20learning" title=" self-supervised learning"> self-supervised learning</a> </p> <a href="https://publications.waset.org/abstracts/153348/masked-candlestick-model-a-pre-trained-model-for-trading-prediction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153348.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">128</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8969</span> Thai Perception on Litecoin Value</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Toby%20Gibbs">Toby Gibbs</a>, <a href="https://publications.waset.org/abstracts/search?q=Suwaree%20Yordchim"> Suwaree Yordchim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research analyzes factors affecting the success of Litecoin Value within Thailand and develops a guideline for self-reliance for effective business implementation. Samples in this study included 119 people through surveys. The results revealed four main factors affecting the success as follows: 1) Future Career training should be pursued in applied Litecoin development. 2) Didn't grasp the concept of a digital currency or see the benefit of a digital currency. 3) There is a great need to educate the next generation of learners on the benefits of Litecoin within the community. 4) A great majority didn't know what Litecoin was. The guideline for self-reliance planning consisted of 4 aspects: 1) Development planning: by arranging meet up groups to conduct further education on Litecoin and share solutions on adoption into every day usage. Local communities need to develop awareness of the usefulness of Litecoin and share the value of Litecoin among friends and family. 2) Computer Science and Business Management staff should develop skills to expand on the benefits of Litecoin within their departments. 3) Further research should be pursued on how Litecoin Value can improve business and tourism within Thailand. 4) Local communities should focus on developing Litecoin awareness by encouraging street vendors to accept Litecoin as another form of payment for services rendered. <p
