We analyse the impact of an entry threat at the downstream level on the ability of a pair of vertically integrated incumbents to collude. We present an original model of horizontal product differentiation on the final market and characterize the structures of this market for which an entry...

In this paper, we study an imperfect monitoring model of duopoly under similar settings as in Green and Porter (1984), but here firms do not know the demand parameters and learn about them over time though the price signals. We investigate how a deviation from rational expectations affects the...

In many cases, collusive agreements are formed by asymmetric firms and include only a subset of the firms active in the cartelized industry. This paper endogenizes the process of cartel formation in a numeric simulation model where firms differ in marginal costs and production technologies. The...

We study the pricing policy equilibria emerging in a partial collusion duopolistic framework where firms in the first stage of the game choose non-cooperatively whether to price discriminate or not, and from the second stage onward collude on prices.When the discount factor is particularly high...

In this paper, we assess the effects of the investigations carried by the Turkish Competition Board in 1997, 2002 and 2003 on the degree competition in the Turkish cement market. For this aim, we used proverbial Bresnahan-Lau framework with alternative definitions for the supply relation. Our...

This paper presents some of the most important microeconomic tools used in assessing antitrust and merger cases by the competition authorities. By explaining the way that microeconomic concepts like “market power”, “critical loss” or “price elasticity of demand” are used by the...

Tracking online user behavior is essential for targeted advertising and is at the heart of the business model of major online platforms. We analyze tracker-specific web browsing data to show how the prediction quality of consumer profiles varies with data size and scope. We find decreasing...

It is usually believed that higher competition, implying more active firms, benefits consumers. We show that this may not be the case in an industry with asymmetric cost firms. A rise in the number of more cost inefficient firms makes the consumers worse-off in the presence of a welfare...

Predatory pricing doctrine is currently a dead area of the law. To proceed beyond summary judgment, a plaintiff must prove the predation created a “dangerous probability” of supracompetitive pricing as the mechanism for recouping the losses “invested” in the predation. This requires...

This Article challenges the various jurisdictional theories that underpin the FCC’s net neutrality regulation. The assertion of jurisdiction by the FCC over any aspect of the Internet ecosystem has raised populist, congressional, and even judicial rhetoric to a crescendo and resulted in a...
