The paper studies indirect network effects in a market composed by two incompatible intermediaries that choose price (short-term issue) in addition to location (long-term issue). The paper first shows that (i) when the network externality is sufficiently weak, only maximum differentiation...

Industrial organization is mainly concerned with the behavior of large firms, especially when it comes to oligopoly theory. Experimental industrial organization therefore faces a problem: How can firms be brought into the laboratory? The main approach relies on framing: Call individuals firms!...

The authors study pure strategy Bertrand equilibria in a duopoly in which two firms produce a homogeneous good with convex cost functions, and they seek to maximize the weighted sum of their absolute and relative profits. They show that there exists a range of the equilibrium price in...

This paper discusses a simultaneous market entry game between two firms with different fixed costs. This case is a typical application of mixed strategy equilibria. Conventional wisdom would suggest that the low-cost firm is more likely to enter the market. This presumption is wrong. Instead,...

This paper demonstrates that the Bertrand paradox does not hold if cost functions are strictly convex. Instead, multiple equilibria exist which can be Pareto-ranked. The paper shows that the Pareto-dominant equilibrium may imply profus higher than in Cournot competition or may even sustain...

This paper investigates the implications for international markets of the existence of retailers/wholesalers with market power. Two main results are shown. First, in the presence of buyer power trade liberalization may lead to retail market concentration. Due to this concentration retail prices...

This paper reviews some of the economic experimental evidence on conformism. There is nothing to match the early psychology experiments where subjects were often swayed by the behaviour of others to an extraordinary degree, but there is plenty of evidence of conformism. This seems built-in to...

In 2011, price peaks in retail gasoline prices caused public outrage and attracted the attention of German regulatory agencies. After having examined the market, competition authorities concluded that tacit collusion existed but could not easily be prosecuted under the given competition law. In...

The author analyses delegation in homogenous duopoly under the assumption that the firm-managers compete in supply functions. In supply function equilibrium, managers' decisions are strategic complements. This reverses earlier findings in that the author finds that owners give managers...

Bilateral trade and capital flows have increased substantially between the United States and China yielding economic gains to both countries. However, these beneficial bilateral relations also bring about global environmental consequences including greenhouse gas emissions. We develop a...
