Through an in-depth reflection spanning multi-sided media markets, information disclosure policies, and the telecommunications sector, this thesis elucidates the intricate interplay between consumer behavior, firm strategies, and market outcomes. From the nuanced implications of multipurchasing behavior on firms’ differentiation strategies to the complex dynamics of decision-making transparency and the strategic responses of incumbents and new entrants in telecommunications, this work offers valuable insights for scholars and practitioners alike. By uncovering the underlying mechanisms driving market behavior and strategic decision-making, “Economics of digital markets’’ equips readers with the knowledge and tools to navigate and thrive in today’s rapidly evolving business landscape.</p> <p><strong>Read the Introduction by <a href="https://www.concurrences.com/en/auteur/Thibaud-Verge">Thibaud Vergé</a>, the Foreword by <a href="https://www.concurrences.com/fr/auteur/Marc-Bourreau">Marc Bourreau</a>, Browse the Table of Contents <a href="en/document/digitalmarkets_demo_v2" class="spip_in" type='application/pdf'>here</a>.</strong></p> <p>The book was awarded the 2023 <a href="https://www.concurrences.com/en/concurrences-ph-d-thesis-awards">Concurrences Ph.D. Award in Economics</a>.</p></div> </div> <aside> <div class="temoignages-wrapper"> <h2>Testimonials</h2> <div itemprop="aggregateRating" itemtype="https://schema.org/AggregateRating" itemscope hidden> <meta itemprop="reviewCount" content="3" /> <meta itemprop="ratingValue" content="~" /> </div> <div class="temoignages carousel slide has-indicators" data-ride="carousel" data-interval="10000" id="temoignages_120295" > <ol class="carousel-indicators"> <li data-target="#temoignages_120295" data-slide-to="0" class="active"></li> <li data-target="#temoignages_120295" data-slide-to="1"></li> <li data-target="#temoignages_120295" data-slide-to="2"></li> </ol> <ul class="liste-items liste-items-well carousel-inner"> <li class="item active"> <div class="entry temoignage hentry" itemprop="review" itemscope itemtype="http://schema.org/Review"> <div class="entry auteur" itemprop="author" itemscope itemtype="http://schema.org/Person"> <strong class="entry-title"> <a href="en/authors/marc-bourreau" itemprop="url"> <span class='logo-img-wrapper spip_logo' style="width:100px;"><span class="img" style="display:block;position:relative;height:0;width:100%;padding-bottom:100%;overflow:hidden;background:url(local/cache-vignettes/L200xH200/m_bourreau-54669.jpg?1720530393) no-repeat center;background-size:100%;"> </span></span> <span itemprop="name" class="nom">Marc Bourreau</span></a> </strong> <div class="entry-content"> <span class='organisation' itemprop="worksFor" itemtype="http://schema.org/Organization">Télécom Paris (Paris)</span> </div> <div class="entry-meta"> <span class="pays">France</span> <span class="articles"><em>2</em> contributions</span> <span class="visites"><em>999</em> visits</span> </div> </div> <blockquote class="crayon temoignage-texte-1249 entry-content" itemprop="reviewBody"><p>Dans cet ouvrage, Enrick Arnaud-Joufray aborde des questions importantes de concurrence et de régulation dans le secteur du numérique. Le premier chapitre montre qu’une fusion entre plateformes financées par la publicité peut augmenter la différenciation des services au bénéfice des consommateurs tout en augmentant les prix pour les publicitaires. Le deuxième chapitre met en évidence qu’une régulation des recommandations et des avis mis en avant par les plateformes peut être bénéfique pour les consommateurs. Enfin, le troisième chapitre montre que l’entrée d’un nouvel opérateur mobile affecte le comportement des opérateurs en place différemment s’ils fournissent l’accès à leur réseau au nouvel entrant. Ces travaux novateurs, à la fois théoriques et empiriques, contribuent à la compréhension des industries de réseau et du numérique. Ils apportent aussi de nouvelles perspectives sur les politiques publiques à mener dans ces secteurs.</p></blockquote> </div> </li> <li class="item"> <div class="entry temoignage hentry" itemprop="review" itemscope itemtype="http://schema.org/Review"> <div class="entry auteur" itemprop="author" itemscope itemtype="http://schema.org/Person"> <strong class="entry-title"> <a href="en/auteurs/bruno-jullien" itemprop="url"> <span class='logo-img-wrapper spip_logo' style="width:100px;"><span class="img" style="display:block;position:relative;height:0;width:100%;padding-bottom:100%;overflow:hidden;background:url(local/cache-vignettes/L200xH200/auton28955-2ff75.png?1711383075) no-repeat center;background-size:100%;"> </span></span> <span itemprop="name" class="nom">Bruno Jullien</span></a> </strong> <div class="entry-content"> <span class='organisation' itemprop="worksFor" itemtype="http://schema.org/Organization">Toulouse School of Economics</span> </div> <div class="entry-meta"> <span class="pays">France</span> <span class="articles"><em>1</em> contribution</span> <span class="visites"><em>158</em> visits</span> </div> </div> <blockquote class="crayon temoignage-texte-1247 entry-content" itemprop="reviewBody"><p>Cet ouvrage offre des perspectives nouvelles et originales sur la compétition entre plateformes ainsi que dans le domaine des télécommunications.

Le premier chapitre éclaire d’une façon originale les stratégies de différenciation des plateformes mais également les conséquences de leur fusion potentielle. Le chapitre 2 propose une analyse novatrice des impacts de la régulation de l’information diffusée en ligne, fournissant ainsi un cadre fructueux pour penser le contrôle des acteurs numériques. Le troisième chapitre étudie l’impact de l’entrée d’un nouvel opérateur de télécoms au Chili sur les stratégies des firmes en place et donc sur les consommateurs. Ces trois chapitres permettent de mieux comprendre les conséquences du pouvoir de marché dans l’économie numérique.
