We investigate the effects of alternative open access regimes on market performance. In particular, by means of an economic laboratory experiment we compare the market outcomes under unregulated wholesale competition, under a price-fixing rule (where firms must maintain their wholesale price for...

We systematically investigate the relationship between the number of firms in a market and tacit collusion by means of a meta-analysis of the literature on oligopoly experiments as well as two of our own experiments with a total of 368 participants. We show that the degree of tacit collusion...

We conduct oligopoly competition experiments with differentiated goods in discrete and continuous time. Continuous time experiments allow for real-time, asynchronous strategic interaction and are therefore argued to be a more realistic mode of interaction, particularly in the context of...

Although the regulation of access to an essential upstream resource is a perennial issue for policymakers and industry stakeholders, a set of new issues arises when there is more than one vertically integrated access provider such that competition at the wholesale level may emerge in addition to...

Conventional wisdom attributes different economic outcomes of uniform pricing and price discrimination to the heterogeneity in market conditions or market participants, such as differences in demand elasticity or production costs. We offer a new explanation for the observed differences that...
