Second, it identifies the smart (electricity) meter market as a multi-sided market and applies the insights found in the literature to better regulate a market-driven rollout of smart meters. Chapter 2 examines the determination of the merchant usage fee of a monopolistic unitary payment card network based on the characteristics of the downstream market. Merchants engage in Bertrand competition that allows for an observation of heterogeneous products. My coauthor and I find that the payment card network extracts a part of the economic rent that merchants obtain. The rent, and consequently the merchant usage fee, is increasing in the downstream market size, but decreasing in the price elasticity of consumer demand, as well as in the substitutability of products, and in the fraction of consumers who prefer card payments. Chapter 3 undertakes a similar analysis for Cournot competition among merchants. The merchant usage fee is decreasing in terms of the price elasticity of demand and has an inverse V relationship with regard to the f...
