This paper looks at the effects of different forms of wholesale and retail regulation on retail competition in fixed network telephony markets. We explicitly model two asymmetries between the incumbent operator and a group of homogenous entrants: (i) while the incumbent has zero marginal costs,...

This paper analyzes the pricing incentives facing the U.S. Postal Service due to the change from the Cost of Service Regulation practiced under the Postal Reform Act (PRA) to the Price Cap Regulation required by the Postal Accountability and Enhancement Act (PAEA).

This paper considers the effect of compatibility decisions on consumers and welfare in a setting where the platforms are asymmetric and consumers have to decide both which platform to join and which applications to buy that run on these platforms.

Bolt and Tieman (2008) suggested the prevalence of profit function non-concavity may account for the widespread use of skewed pricing by two-sided platform businesses. In both the Rochet-Tirole (2003) and Armstrong (2006) models, however, skewed pricing may simply reflect substantial differences...

This paper examines the celebrated “strength of weak ties” theory of Granovetter (1973). We examine two hypotheses implied by the theory: one, for any three players with two links present, the probability of a third link being present is increasing in the strength of the two ties, and two, the...

Power generation and transmission are complementary activities that must be coordinated to ensure an optimal use and development of the transmission network. This coordination is today more difficult in a liberalized system, because of unbundling and the freedom for investors to choose their...
