In this note, we introduce a new sufficient condition, called sign-quasiconcavity, on the existence of a pure equilibrium in two-person symmetric zerosum games, which generalizes both generalized ordinal potentials Monderer and Shapley, 1996 and quasiconcavity Duerschet al., 2012.

We illustrate an equivalence between the class of two-person symmetric games and the class of decision problems with a complete preference relation. Moreover, we show that a strategy is an optimal threat strategy Nash, 1953 in a two-person symmetric game if and only if it is a maximal element in...

In this paper we enrich the Brabander (1981) and Brander and Krugman (1983) model of reciprocal entry by placing it i a setting of two-sided asymetric information. Following the limit pricing methodology of Milgrom and Roberts (1982), we show that the limit price is affected by a firm''s desire...

We study experimentally how players learn to make decisions if they face many different (normal-form) games. Games are generated randomly from a uniform distribution in each of 100 rounds. We find that agents do extrapolate between games but learn to play strategically equivalent games in the...

In this paper, we compare experience-earnings profiles of employees with vocational and generaleducation background in Germany, the Netherlands and the United Kingdom, three countries withfundamentally different education systems. Using Mixed-Effects Linear Regression Models we showthat earnings...

In this paper, we combine elementary revealed preference principles and nonparametric estimation techniques in order to obtain nonparametric bounds on the distribution of the money metric utility over a population of heterogeneous households. The main benefit of our approach is that it is...

We record the existence of an availability heuristic that is reflected in disaster myopia of U.S. investors and exists prior to the attacks of 9/11. We argue that this is fueled by an aggregate experience hypothesis effect, resulting in a pronounced increase in the sensitivity of U.S. stock...

We study characterizations of implementable allocation rules when types are multi-dimensional, monetary transfers are allowed, and agents have quasi-linear preferences over outcomes and transfers. Every outcome is associated with a continuous valuation function that maps an agents type to his...

This paper quantifies the effect of reallocation dynamics on aggregate productivity developments in the banking sectors of Europe and the United States. We document an increase in productivity over the period 1995-2009, on the order of 11 in the US and 19 in Europe. At an annual frequency,...

This paper examines endogenous cartel formation in the presence of a competition authority. Competition policy makes the most inclusive stable cartels less inclusive. In particular, small firms that might have been cartel members in the absence of a competition authority are no longer members....
