We study under what conditions mandatory price disclosure is pro- or anticompetitive. Using a theoretical search model with collusion and imperfectly informed consumers and producers, we characterise the circumstances under which increasing price transparency benefits consumers. We show that the...

Wettbewerbspolitisch stellt sich die Frage, ob im 5er-Oligopol mit Aral, Shell, Esso, Total und Jet Binnenwettbewerb fehlt und ob dieses Oligopol wirksam Außenseiterwettbewerb ausgesetzt ist. Nach neuartigen Daten für vier Metropolen aus 2014, die auf die Marktransparenzstelle zurückgehen,...

International openness enhances social interactions between citizens of different countries or regions and vice versa. Social exchanges, in turn, increase trade flows between countries and influence markets and prices. We analyze the increased mobility that follows from openness between two...

We re-consider the bilateral bargaining problem of a multi-product, manufacturer-retailer trading relationship. O'Brien and Shaffer (Rand JE 35:573-598, 2005) have shown that the unbundling of contracts leads to downward distorted production levels if seller power is strong, while otherwise the...

The purpose of this working paper is to bring a behavioral lens to the review and analysis of the competition literature on labour market power, monopsony, and oligopsony, the behavioral and more conventional labour market economics literatures that are relevant to labour market competition and...

Under network effects, we analyze when a firm with the largest market share of installed-base customers prefers incompatibility with smaller rivals that are themselves compatible. With incompatibility, consumers realize that intra-network competition makes the rivals' network more aggressive...

In electricity and other industries, it is increasingly common for a utility's upstream affiliate (i.e., an electric generation supplier) to be unregulated while its downstream affiliate (i.e., the local distribution company offering retail service) is subject to regulation. In these industries,...
