Objectives and Key Themes

This dissertation aims to analyze the dynamics of the evolution of e-commerce, focusing on the role of online intermediaries and their impact on market equilibrium. It uses Groupon.com as a case study to extrapolate statistical evidence and examine intermediary behavior. The theoretical framework draws upon literature on internet economics, information intermediation, reputation systems, and two-sided platforms.

• The impact of the internet on traditional retail models and consumer behavior.
• The role and different types of online intermediaries (dealers, platforms, infomediaries, trusted third parties).
• The influence of reputation and trust in online markets.
• The dynamics of competition in intermediated markets, particularly in the context of group buying.
• The economic and strategic aspects of group-buying infomediaries like Groupon.

Chapter Summaries

Chap I. Internet Economics: This chapter explores the impact of the internet on the economy, examining theories on lower inflation and the impact of internet adoption as a cost-reducing technology. It highlights the role of online intermediaries (OIs) and their potential for monopolistic behavior due to increasing returns to scale and network effects. The chapter concludes by posing questions regarding how OIs exploit their functions and the perception of user costs and profits within the infomediary model.

Chap II. Information and reputation in intermediated product markets: This chapter analyzes the importance of information and reputation in intermediated markets. It examines models of consumer attention, competition among advertisers, and the role of infomediaries as information gatekeepers. The chapter further explores how intermediaries can act as certifiers of product quality and reputation, impacting consumer trust and firm behavior. The case of tour operators providing hotel ratings is used as an example.

Chap III. Markets with intermediated goods: This chapter categorizes the different roles of online intermediaries: dealers, platform operators, infomediaries, and trusted third parties. It examines models of intermediated trade, comparing it to decentralized markets and exploring when intermediation adds value. The chapter analyzes the behavior of intermediaries as dealers versus platform operators, and discusses double marginalization in vertical relationships, using the example of the debit card industry. Finally, it examines the economics of coupon businesses as a response to economic recession.

Chap. IV E-Tailing: The online shopping pandemic: This chapter investigates the relationship between e-tailing and traditional retailing, exploring whether they are complements or substitutes. It uses empirical data from Groupon Italy to analyze the success of group-buying infomediaries. The chapter delves into the Groupon business model, analyzing the strategic interactions between Groupon and its partners ("Partners"), and Groupon and its users. It examines the price negotiation game between Groupon and its partners, using a modified Bertrand model to analyze market power. The chapter also explores the price elasticity of demand for different product categories and the relationship between efficiency, profits, and consumer satisfaction within the Groupon model.
