Hedging is a mitigated word used to lessen the impact of the utterance uttered by the speakers. Hedging could be either adverbs, adjectives, verbs and sometimes it may consist of clauses. It aims at finding out the extent to which speakers and participants of the discourse use hedging constructions during their conversations. The study also aims at finding out whether or not there are any significant differences in the types and functions of the frequency of hedging constructions employed by male and female. It is hypothesized that hedging constructions are frequent in English discourse more than any other languages due to its formality and that the frequency of the types and functions are influenced by the gender of the participants. To achieve the aims of the study, two types of procedures have been followed: theoretical and practical. The theoretical procedure consists of presenting a theoretical background of hedging topic which includes its definitions, etymology and theories. The practical procedure consists of selecting a sample of texts and analyzing them according to an adopted model. A number of conclusions will be drawn based on the findings of the study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hedging" title="hedging">hedging</a>, <a href="https://publications.waset.org/abstracts/search?q=pragmatics" title=" pragmatics"> pragmatics</a>, <a href="https://publications.waset.org/abstracts/search?q=politeness" title=" politeness"> politeness</a>, <a href="https://publications.waset.org/abstracts/search?q=theoretical" title=" theoretical "> theoretical </a> </p> <a href="https://publications.waset.org/abstracts/14661/pragmatic-discoursal-study-of-hedging-constructions-in-english-language" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14661.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">587</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">37</span> The Use of Hedging Devices in Studens’ Oral Presentation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siti%20Navila">Siti Navila</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hedging as a kind of pragmatic competence is an essential part in achieving the goal in communication, especially in academic discourse where the process of sharing knowledge among academic community takes place. Academic discourse demands an appropriateness and modesty of an author or speaker in stating arguments, to name but few, by considering the politeness, being cautious and tentative, and differentiating personal opinions and facts in which these aspects can be achieved through hedging. This study was conducted to find the hedging devices used by students as well as to analyze how they use them in their oral presentation. Some oral presentations from English Department students of the State University of Jakarta on their Academic Presentation course final test were recorded and explored formally and functionally. It was found that the most frequent hedging devices used by students were shields from all hedging devices that students commonly used when they showed suggestion, stated claims, showed opinion to provide possible but still valid answer, and offered the appropriate solution. The researcher suggests that hedging can be familiarized in learning, since potential conflicts that is likely to occur while delivering ideas in academic contexts such as disagreement, criticism, and personal judgment can be reduced with the use of hedging. It will also benefit students in achieving the academic competence with an ability to demonstrate their ideas appropriately and more acceptable in academic discourse. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=academic%20discourse" title="academic discourse">academic discourse</a>, <a href="https://publications.waset.org/abstracts/search?q=hedging" title=" hedging"> hedging</a>, <a href="https://publications.waset.org/abstracts/search?q=hedging%20devices" title=" hedging devices"> hedging devices</a>, <a href="https://publications.waset.org/abstracts/search?q=lexical%20hedges" title=" lexical hedges"> lexical hedges</a>, <a href="https://publications.waset.org/abstracts/search?q=Meyer%20classification" title=" Meyer classification"> Meyer classification</a> </p> <a href="https://publications.waset.org/abstracts/31732/the-use-of-hedging-devices-in-studens-oral-presentation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31732.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">460</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">36</span> Optimal Hedging of a Portfolio of European Options in an Extended Binomial Model under Proportional Transaction Costs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Norm%20Josephy">Norm Josephy</a>, <a href="https://publications.waset.org/abstracts/search?q=Lucy%20Kimball"> Lucy Kimball</a>, <a href="https://publications.waset.org/abstracts/search?q=Victoria%20Steblovskaya"> Victoria Steblovskaya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hedging of a portfolio of European options under proportional transaction costs is considered. Our discrete time financial market model extends the binomial market model with transaction costs to the case where the underlying stock price ratios are distributed over a bounded interval rather than over a two-point set. An optimal hedging strategy is chosen from a set of admissible non-self-financing hedging strategies. Our approach to optimal hedging of a portfolio of options is based on theoretical foundation that includes determination of a no-arbitrage option price interval as well as on properties of the non-self-financing strategies and their residuals. A computational algorithm for optimizing an investor relevant criterion over the set of admissible non-self-financing hedging strategies is developed. Applicability of our approach is demonstrated using both simulated data and real market data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=extended%20binomial%20model" title="extended binomial model">extended binomial model</a>, <a href="https://publications.waset.org/abstracts/search?q=non-self-financing%20hedging" title=" non-self-financing hedging"> non-self-financing hedging</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=proportional%20transaction%20costs" title=" proportional transaction costs"> proportional transaction costs</a> </p> <a href="https://publications.waset.org/abstracts/83333/optimal-hedging-of-a-portfolio-of-european-options-in-an-extended-binomial-model-under-proportional-transaction-costs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83333.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">252</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">35</span> Hedging and Corporate Governance: Lessons from the Financial Crisis </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rodrigo%20Zeidan">Rodrigo Zeidan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper identifies failures of decision making and corporate governance that allow non-financial companies around the world to develop hedging strategies that lead to hefty losses in the aftermath of the financial crisis. The sample is comprised of 346 companies from 10 international markets, of which 49 companies (and a subsample of 13 distressed companies) lose a combined US$18.9 billion. An event study shows that most companies that present losses in derivatives experience negative abnormal returns, including a number of companies in which the effect is persistent after a year. The results of a probit model indicate that the lack of a formal hedging policy, no monitoring to the CFOs, and considerations of hubris and remuneration contribute to the mismanagement of hedging policies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=risk%20management" title="risk management">risk management</a>, <a href="https://publications.waset.org/abstracts/search?q=hedging" title=" hedging"> hedging</a>, <a href="https://publications.waset.org/abstracts/search?q=derivatives" title=" derivatives"> derivatives</a>, <a href="https://publications.waset.org/abstracts/search?q=monitoring" title=" monitoring"> monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=corporate%20governance%20structure" title=" corporate governance structure"> corporate governance structure</a>, <a href="https://publications.waset.org/abstracts/search?q=event%20study" title=" event study"> event study</a>, <a href="https://publications.waset.org/abstracts/search?q=hubris" title=" hubris"> hubris</a> </p> <a href="https://publications.waset.org/abstracts/3438/hedging-and-corporate-governance-lessons-from-the-financial-crisis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3438.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">442</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">34</span> Exploring the Changing Foreign Policy of Singapore on China: New Ideas of Pragmatism and Hedging Strategy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yibo%20Shao">Yibo Shao</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiajie%20Liu"> Jiajie Liu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article uncovers the practice of pragmatism of Singaporean foreign policy by analyzing its foreign diplomatic behavior.

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">310</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">31</span> The Determinants of Corporate Hedging Strategy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ademola%20Ajibade">Ademola Ajibade</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Previous studies have explored several rationales for hedging strategies, but the evidence provided by these studies remains ambiguous. Using a hand-collected dataset of 2460 observations of non-financial firms in eight African countries covering 2013-2022, this paper investigates the determinants and extent of corporate hedge use. In particular, this paper focuses on the link between country-specific conditions and the corporate hedging behaviour of firms. To our knowledge, this represents the first African studies investigating the association between country-specific factors and corporate hedging policy. The evidence based on both univariate and multivariate reveal that country-level corruption and government quality are important indicators of the decisions and extent of hedge use among African firms. However, the connection between country-specific factors as a rationale for corporate hedge use is stronger for firms located in highly corrupt countries. This suggest that firms located in corrupt countries are more motivated to hedge due to the large exposure they face. In addition, we test the risk management theories and observe that CEOs educational qualification and experience shape corporate hedge behaviour. We implement a lagged variables in a panel data setting to address endogeneity concern and implement an interaction term between governance indices and firm-specific variables to test for robustness. Generally, our findings reveal that institutional factors shape risk management decisions and have a predictive power in explaining corporate hedging strategy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corporate%20hedging" title="corporate hedging">corporate hedging</a>, <a href="https://publications.waset.org/abstracts/search?q=governance%20quality" title=" governance quality"> governance quality</a>, <a href="https://publications.waset.org/abstracts/search?q=corruption" title=" corruption"> corruption</a>, <a href="https://publications.waset.org/abstracts/search?q=derivatives" title=" derivatives"> derivatives</a> </p> <a href="https://publications.waset.org/abstracts/164683/the-determinants-of-corporate-hedging-strategy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164683.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">92</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">30</span> Waad Bil Mourabaha Pricing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dchieche%20Amina">Dchieche Amina</a>, <a href="https://publications.waset.org/abstracts/search?q=Aboulaich%20Rajae"> Aboulaich Rajae</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, we will modelize Waad Bil Mourabaha contract.

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">378</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">28</span> Grand Paris Residential Real Estate as an Effective Hedge against Inflation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yasmine%20Essafi%20Zouari">Yasmine Essafi Zouari</a>, <a href="https://publications.waset.org/abstracts/search?q=Aya%20Nasreddine"> Aya Nasreddine</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Following a long inflationary period from the post-war era to the mid-1980s (+10.1% annually), France went through a moderate inflation period between 1986 and 2001 (+2.1% annually) and even lower inflation between 2002 and 2016 (+1.4% annually). In 2022, inflation in France increased rapidly and reached 4.5% over one year in March, according to INSEE estimates. Over a long period, even low inflation has an impact on portfolio value and households’ purchasing power. In such a context, inflation hedging should remain an important issue for investors. In particular, long-term investors, who are concerned with the protection of their wealth, seek to hold effective hedging assets. Considering a mixed-asset portfolio composed of housing assets (residential real estate in 150 Grand Paris communes) as well as financial assets, and using both correlation and regression analysis, results confirm the attribute of the direct housing investment as an inflation hedge especially particularly against its unexpected component. Further, cash and bonds were found to provide respectively a partial and an over hedge against unexpected inflation. Stocks act as a perverse hedge against unexpected inflation and provide no significant positive hedge against expected inflation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=direct%20housing" title="direct housing">direct housing</a>, <a href="https://publications.waset.org/abstracts/search?q=inflation" title=" inflation"> inflation</a>, <a href="https://publications.waset.org/abstracts/search?q=hedging%20ability" title=" hedging ability"> hedging ability</a>, <a href="https://publications.waset.org/abstracts/search?q=optimal%20portfolio" title=" optimal portfolio"> optimal portfolio</a>, <a href="https://publications.waset.org/abstracts/search?q=Grand%20Paris%20metropolis" title=" Grand Paris metropolis"> Grand Paris metropolis</a> </p> <a href="https://publications.waset.org/abstracts/150286/grand-paris-residential-real-estate-as-an-effective-hedge-against-inflation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150286.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">113</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">27</span> Regionalism or Ladder-Up: A Theoretical Perspective of Association of Southeast Asian Nations’ Reactions to Belt and Road Initiative</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yunqi%20Wang">Yunqi Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As a vital region to the Chinese Belt and Road Initiative (BRI), members of the Association of Southeast Asian Nations (ASEAN) have responded to the grand strategy differently. Some expressed fervent support, while others played the 'hedging' card between great powers. This paper explores the underlying rationale behind such complexity by proposing two theoretical explanations: a Regionalism Hypothesis, where countries respond with hedging, balancing, and bandwagoning behaviours in line with national interests and norm-based 'ASEAN-Way'; and a Ladder-up Hypothesis, where countries consider the initiative as an incentive to remove bottlenecks of climbing up the economic ladder in Rostow's stage of the growth model. By analysing reactions from Myanmar, Laos, Indonesia, and Singapore, two patterns are observed. On an empirical note, the more developed economies are more inclined to the Regionalist explanation. On a theoretical note, there has been a gradual convergence between the two explanations, given the impact of economic globalisation on ASEAN. This paper will contribute to the current theoretical vacancy in the study of ASEAN and BRI by capturing the particular norms shared by this regional entity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ASEAN" title="ASEAN">ASEAN</a>, <a href="https://publications.waset.org/abstracts/search?q=belt%20and%20road%20initiative" title=" belt and road initiative"> belt and road initiative</a>, <a href="https://publications.waset.org/abstracts/search?q=hedging" title=" hedging"> hedging</a>, <a href="https://publications.waset.org/abstracts/search?q=Rostow%27s%20stages%20of%20growth" title=" Rostow's stages of growth"> Rostow's stages of growth</a>, <a href="https://publications.waset.org/abstracts/search?q=regionalism" title=" regionalism"> regionalism</a> </p> <a href="https://publications.waset.org/abstracts/152049/regionalism-or-ladder-up-a-theoretical-perspective-of-association-of-southeast-asian-nations-reactions-to-belt-and-road-initiative" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152049.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">117</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">26</span> Managing Sunflower Price Risk from a South African Oil Crushing Company’s Perspective</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Mokatsanyane">Daniel Mokatsanyane</a>, <a href="https://publications.waset.org/abstracts/search?q=Johnny%20Jansen%20Van%20Rensburg"> Johnny Jansen Van Rensburg</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The integral role oil-crushing companies play in sunflower oil production is often overlooked to offer high-quality oil to refineries and end consumers. Sunflower oil crushing companies in South Africa are exposed to price fluctuations resulting from the local and international markets. Hedging instruments enable these companies to hedge themselves against unexpected prices spikes and to ensure sustained profitability. A crushing company is a necessary middleman, and as such, these companies have exposure to the purchasing and selling sides of sunflower. Sunflower oil crushing companies purchase sunflower seeds from farmers or agricultural companies that provide storage facilities. The purchasing price is determined by the supply and demand of sunflower seed, both national and international. When the price of sunflower seeds in South Africa is high but still below import parity, then the crush margins realised by these companies are reduced or even negative at times. There are three main products made by sunflower oil crushing companies, oil, meal, and shells. Profits are realised from selling three products, namely, sunflower oil, meal and shells. However, when selling sunflower oil to refineries, sunflower oil crushing companies needs to hedge themselves against a reduction in vegetable oil prices. Hedging oil prices is often done via futures and is subject to specific volume commitments before a hedge position can be taken in. Furthermore, South African oil-crushing companies hedge sunflower oil with international, Over-the-counter contracts as South Africa is a price taker of sunflower oil and not a price maker. As such, South Africa provides a fraction of the world’s sunflower oil supply and, therefore, has minimal influence on price changes. The advantage of hedging using futures ensures that the sunflower crushing company will know the profits they will realise, but the downside is that they can no longer benefit from a price increase. Alternative hedging instruments like options might pose a solution to the opportunity cost does not go missing and that profit margins are locked in at the best possible prices for the oil crushing company. This paper aims to investigate the possibility of employing options alongside futures to simulate different scenarios to determine if options can bridge the opportunity cost gap. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=derivatives" title="derivatives">derivatives</a>, <a href="https://publications.waset.org/abstracts/search?q=hedging" title=" hedging"> hedging</a>, <a href="https://publications.waset.org/abstracts/search?q=price%20risk" title=" price risk"> price risk</a>, <a href="https://publications.waset.org/abstracts/search?q=sunflower" title=" sunflower"> sunflower</a>, <a href="https://publications.waset.org/abstracts/search?q=sunflower%20oil" title=" sunflower oil"> sunflower oil</a>, <a href="https://publications.waset.org/abstracts/search?q=South%20Africa" title=" South Africa"> South Africa</a> </p> <a href="https://publications.waset.org/abstracts/142388/managing-sunflower-price-risk-from-a-south-african-oil-crushing-companys-perspective" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142388.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">165</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">25</span> Islamic Financial Engineering: An Overview</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahfoud%20Djebbar">Mahfoud Djebbar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The past two decades or so have witnessed phenomenal growth of the Islamic financial services industry.

At the same time, with the intensification of the Ukraine crisis, the United States and European countries have imposed severe economic sanctions on Russia to prevent and contain Russia's special military operations against Ukraine. The essence of the Ukraine crisis is a geopolitical conflict and competition between Russia and the United States. For a long time, the United States has always regarded Russia as a serious strategic crisis and challenge. Therefore, for the United States, the outbreak of the Ukraine crisis is an extremely important opportunity to condemn and stop Russia's actions from an international perspective. In this process, China plays a very special role. This special positioning is not only reflected in the long-term friendly relationship between China and Russia and mutual support and assistance on the international stage but also in the complex economic relationship and interdependence between China and the United States. Therefore, China has adopted a "hedging strategy" in dealing with the Ukrainian crisis, and the use of the hedging strategy not only plays a special role in safeguarding China's own security and interests but also because China can act as an intermediary to coordinate Russia and the United States to promote the resolution of the Ukrainian crisis in a peaceful manner. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ukraine%20crisis%20Russia-Ukraine%20conflict%20balanced%20strategy%20Sino-US%20competition" title="Ukraine crisis Russia-Ukraine conflict balanced strategy Sino-US competition">Ukraine crisis Russia-Ukraine conflict balanced strategy Sino-US competition</a> </p> <a href="https://publications.waset.org/abstracts/160912/chinas-hedging-strategy-in-response-to-the-russia-ukraine-conflict" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160912.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">83</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">23</span> Volatility Spillover and Hedging Effectiveness between Gold and Stock Markets: Evidence for BRICS Countries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Walid%20Chkili">Walid Chkili</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper investigates the dynamic relationship between gold and stock markets using data for BRICS counties.

Empirical results reveal that dynamic conditional correlations switch between positive and negative values over the period under study. This correlation is negative during the major financial crises suggesting that gold can act as a safe haven during the major stress period of stock markets.

Derivatives are complex instruments; their valuation, volatility implications, and real impact on the underlying assets' behaviour are not well understood. Little is documented empirically, with conflicting conclusions on how these instruments affect firm risk exposures. Given the growing interest in using derivatives in risk management and portfolio engineering, this study examines the practical impact of derivative usage on the underlying stock price exposure and systematic risk. The paper uses data from South African listed firms. The study employs GARCH models to understand the effect of derivative uses on conditional stock volatility. The GMM models are used to estimate the effect of derivatives use on stocks' systematic risk as measured by Beta and on the total risk of stocks as measured by the standard deviation of returns. The results provide evidence on whether derivatives use is instrumental in reducing stock returns' systematic and total risk. The results are subjected to numerous controls for robustness, including financial leverage, firm size, growth opportunities, and macroeconomic effects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=derivatives%20use" title="derivatives use">derivatives use</a>, <a href="https://publications.waset.org/abstracts/search?q=hedging" title=" hedging"> hedging</a>, <a href="https://publications.waset.org/abstracts/search?q=volatility" title=" volatility"> volatility</a>, <a href="https://publications.waset.org/abstracts/search?q=stock%20price%20exposure" title=" stock price exposure"> stock price exposure</a> </p> <a href="https://publications.waset.org/abstracts/156599/an-empirical-analysis-of-the-effects-of-corporate-derivatives-use-on-the-underlying-stock-price-exposure-south-african-evidence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156599.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">108</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">21</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">20</span> Climate Change, Agriculture and Food Security in Sub-Saharan Africa: What Effects and What Answers?</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdoulahad%20Allamine">Abdoulahad Allamine</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this study is to assess the impact of climate variability on agriculture and food security in 43 countries of sub-Saharan Africa. We use for this purpose the data from BADC bases, UNCTAD, and WDI FAOSTAT to estimate a VAR model on panel data. The sample is divided into three (03) agro-climatic zones, more explicitly the equatorial zone, the Sahel region and the semi-arid zone. This allows to highlight the differential impacts sustained by countries and appropriate responses to each group of countries. The results show that the sharp fluctuations in the volume of rainfall negatively affect agriculture and food security of countries in the equatorial zone, with heavy rainfall and high temperatures in the Sahel region. However, countries with low temperatures and low rainfall are the least affected. The hedging policies against the risks of climate variability must be more active in the first two groups of countries. On this basis and in general, we recommend integration of agricultural policies between countries is done to reduce the effects of climate variability on agriculture and food security. It would be logical to encourage regional and international closer collaboration on the development and dissemination of improved varieties, ecological intensification, and management of biotic and abiotic stresses facing these climate variability to sustainably increase food production. Small farmers also need training in agricultural risk hedging techniques related to climate variations; this requires an increase in state budgets allocated to agriculture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agro-climatic%20zones" title="agro-climatic zones">agro-climatic zones</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20variability" title=" climate variability"> climate variability</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20security" title=" food security"> food security</a>, <a href="https://publications.waset.org/abstracts/search?q=Sub-Saharan%20Africa" title=" Sub-Saharan Africa"> Sub-Saharan Africa</a>, <a href="https://publications.waset.org/abstracts/search?q=VAR%20on%20panel%20data" title=" VAR on panel data"> VAR on panel data</a> </p> <a href="https://publications.waset.org/abstracts/32553/climate-change-agriculture-and-food-security-in-sub-saharan-africa-what-effects-and-what-answers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32553.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">388</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">19</span> Method to Find a ε-Optimal Control of Stochastic Differential Equation Driven by a Brownian Motion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Francys%20Souza">Francys Souza</a>, <a href="https://publications.waset.org/abstracts/search?q=Alberto%20Ohashi"> Alberto Ohashi</a>, <a href="https://publications.waset.org/abstracts/search?q=Dorival%20Leao"> Dorival Leao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We present a general solution for finding the ε-optimal controls for non-Markovian stochastic systems as stochastic differential equations driven by Brownian motion, which is a problem recognized as a difficult solution. The contribution appears in the development of mathematical tools to deal with modeling and control of non-Markovian systems, whose applicability in different areas is well known. The methodology used consists to discretize the problem through a random discretization. In this way, we transform an infinite dimensional problem in a finite dimensional, thereafter we use measurable selection arguments, to find a control on an explicit form for the discretized problem. Then, we prove the control found for the discretized problem is a ε-optimal control for the original problem. Our theory provides a concrete description of a rather general class, among the principals, we can highlight financial problems such as portfolio control, hedging, super-hedging, pairs-trading and others. Therefore, our main contribution is the development of a tool to explicitly the ε-optimal control for non-Markovian stochastic systems. The pathwise analysis was made through a random discretization jointly with measurable selection arguments, has provided us with a structure to transform an infinite dimensional problem into a finite dimensional. The theory is applied to stochastic control problems based on path-dependent stochastic differential equations, where both drift and diffusion components are controlled. We are able to explicitly show optimal control with our method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20programming%20equation" title="dynamic programming equation">dynamic programming equation</a>, <a href="https://publications.waset.org/abstracts/search?q=optimal%20control" title=" optimal control"> optimal control</a>, <a href="https://publications.waset.org/abstracts/search?q=stochastic%20control" title=" stochastic control"> stochastic control</a>, <a href="https://publications.waset.org/abstracts/search?q=stochastic%20differential%20equation" title=" stochastic differential equation"> stochastic differential equation</a> </p> <a href="https://publications.waset.org/abstracts/94746/method-to-find-a-e-optimal-control-of-stochastic-differential-equation-driven-by-a-brownian-motion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94746.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">188</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">18</span> Modeling Salam Contract for Profit and Loss Sharing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dchieche%20Amina">Dchieche Amina</a>, <a href="https://publications.waset.org/abstracts/search?q=Aboulaich%20Rajae"> Aboulaich Rajae</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Profit and loss sharing suggests an equitable sharing of risks and profits between the parts involved in a financial transaction.

The problem is further exacerbated by commodities volatility caused by other commodity price fluctuations, hence the decision on hedging strategy has become both costly and useless. Thus, this paper is conducted to analysis the volatility spillover effect among major agriculture including corn, soybeans, wheat and rice, to help the commodity suppliers hedge their portfolios, and manage the risk and co-volatility of them. We provide a switching regime approach to analyzing the issue of volatility spillovers in different economic conditions, namely upturn and downturn economic. In particular, we investigate relationships and volatility transmissions between these commodities in different economic conditions. We purposed a Copula-based multivariate Markov Switching GARCH model with two regimes that depend on an economic conditions and perform simulation study to check the accuracy of our proposed model. In this study, the correlation term in the cross-hedge ratio is obtained from six copula families – two elliptical copulas (Gaussian and Student-t) and four Archimedean copulas (Clayton, Gumbel, Frank, and Joe). We use one-step maximum likelihood estimation techniques to estimate our models and compare the performance of these copula using Akaike information criterion (AIC) and Bayesian information criteria (BIC). In the application study of agriculture commodities, the weekly data used are conducted from 4 January 2005 to 1 September 2016, covering 612 observations. The empirical results indicate that the volatility spillover effects among cereal futures are different, as response of different economic condition. In addition, the results of hedge effectiveness will also suggest the optimal cross hedge strategies in different economic condition especially upturn and downturn economic. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agricultural%20commodity%20futures" title="agricultural commodity futures">agricultural commodity futures</a>, <a href="https://publications.waset.org/abstracts/search?q=cereal" title=" cereal"> cereal</a>, <a href="https://publications.waset.org/abstracts/search?q=cross-hedge" title=" cross-hedge"> cross-hedge</a>, <a href="https://publications.waset.org/abstracts/search?q=spillover%20effect" title=" spillover effect"> spillover effect</a>, <a href="https://publications.waset.org/abstracts/search?q=switching%20regime%20approach" title=" switching regime approach"> switching regime approach</a> </p> <a href="https://publications.waset.org/abstracts/58830/modelling-volatility-spillovers-and-cross-hedging-among-major-agricultural-commodity-futures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58830.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">202</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">16</span> A Financial Analysis of the Current State of IKEA: A Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Isabela%20Vieira">Isabela Vieira</a>, <a href="https://publications.waset.org/abstracts/search?q=Leonor%20Carvalho%20Garcez"> Leonor Carvalho Garcez</a>, <a href="https://publications.waset.org/abstracts/search?q=Adalmiro%20Pereira"> Adalmiro Pereira</a>, <a href="https://publications.waset.org/abstracts/search?q=T%C3%A2nia%20Teixeira"> Tânia Teixeira</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present work, we aim to analyse IKEA as a company, by focusing on its development, financial analysis and future benchmarks, as well as applying some of the knowledge learned in class, namely hedging and other financial risk mitigation solutions, to understand how IKEA navigates and protects itself from risk.

The main focus in determining whether there are similarities or differences between those financial products is the tracking error. The importance of understanding the similarities or differences between the gold ETFs, gold mutual funds and gold prices is derived from the fact that gold ETFs and gold mutual funds are used as substitutions for investors who are looking to profit from gold prices although they are short in capital. 10 hypotheses were tested. There are 3 types of tracking error used. Tracking error 1 and 3 gives results that differentiate between types of ETFs and mutual funds, hence yielding the answers in answering the hypotheses that were developed. However, tracking error 2 failed to give the answer that could shed light on the questions raised in this study.

On the other hand, emails have recently become one of the indispensable means of communication in educational settings. This research puts email communication at the core of the study and analyses it from a politeness perspective. More specifically, it endeavours to look closely at how the concept of (im)politeness is reflected through students’ emails. To this end, a corpus of Algerian supervisees’ email threads, exchanged with their Irish supervisors, was compiled. Leech’s model of politeness (2014) was selected as the main theoretical framework of this study, in addition to making reference to Brown and Levinson’s model (1987) as it is one of the most influential models in the area of pragmatic politeness. Further, some follow-up interviews are to be conducted with Algerian students to reinforce the results derived from the corpus. Initial findings suggest that Algerian Ph.D. students’ emails tend to include more politeness markers than impoliteness ones, they heavily make use of academic titles when addressing their supervisors (Dr. or Prof.), and they rely on hedging devices in order to sound polite. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=politeness" title="politeness">politeness</a>, <a href="https://publications.waset.org/abstracts/search?q=email%20communication" title=" email communication"> email communication</a>, <a href="https://publications.waset.org/abstracts/search?q=corpus%20pragmatics" title=" corpus pragmatics"> corpus pragmatics</a>, <a href="https://publications.waset.org/abstracts/search?q=Algerian%20PhD%20supervisees" title=" Algerian PhD supervisees"> Algerian PhD supervisees</a>, <a href="https://publications.waset.org/abstracts/search?q=Irish%20supervisors" title=" Irish supervisors"> Irish supervisors</a> </p> <a href="https://publications.waset.org/abstracts/176737/investigating-impoliteness-strategies-in-email-communication-the-case-algerian-phd-supervisees-and-irish-supervisors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176737.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">70</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">10</span> Risk Spillover Between Stock Indices and Real Estate Mixed Copula Modeling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hina%20Munir%20Abbasi">Hina Munir Abbasi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The current paper examines the relationship and diversification ability of Islamic stock indices /conventional stocks indices and Real Estate Investment Trust (REITs).To represent conditional dependency between stocks and REITs in a more realistic way, new modeling technique, time-varying copula with switching dependence is used.

Subcontracting is available as support to satisfy product demand; also overhaul maintenance can be conducted to reduce the effects of deterioration. The main objective of the research is to determine simultaneously the production, maintenance and subcontracting rate which minimize the total incurred cost. A stochastic dynamic programming model is developed and solved through a simulation-based approach composed of statistical analysis and optimization with the response surface methodology. The obtained results highlight the strong interactions between production, deterioration and quality which justify the development of an integrated model. A numerical example and a sensitivity analysis are presented to validate our results. <p class="card-text"><strong>Keywords:</strong> <a
