In this note we take a first step towards the analysis of collusion in markets with spatial competition, focusing on the case of pure location choices. We find that collusion can only be profitable if a coalition contains more than half of all players. This result holds for location games played...

In this note we consider the preferences of a profit maximizing firm for international ownership in a world in which firms compete in an international Cournot oligopoly, and in which countries use strategic trade policy. We find that firms prefer national ownership and show that full...

We study the profitability and welfare effects of merger in a strategic trade policy environment. Merger changes the strategic trade policy equilibrium. We show that merger can be profitable and welfare enhancing here, even though it is not profitable in a laissez-faire economy. A key element is...

Competition in some product markets takes the form of a contest. If some firms cooperate in such markets, they must decide how to allocate effort on each of their products and whether to reduce the number of their products in the competition. We show how this decision depends on the convexity...

Consider a committee that in the past has made a promise not to confiscate the profits from a foreign investor. After the investment has taken place, there is a material benefit if the committee decides to default on the earlier promise. But there are also some small moral costs for those who...

Often information structures are such that while individual reputation building is impossible groups of agents would have the possibility of building up a reputation. We experimentally examine whether groups of sellers in markets that suffer from moral hazard are able to build up reputations...

We introduce a new model of aggregate information cascades where only one of two possible actions is observable to others. When called upon, agents (who decide in some random order that they do not know) are only informed about the total number of others who have chosen the observable action...

We test the no-trade theorem in a laboratory nancial market where subjects can trade an asset whose value is unknown. Subjects receive clues on the asset value and then set a bid and an ask at which they are willing to buy or to sell from the other participants. In treatments with no gains from...

We study experimentally a standard four-player Hotelling game, with a uniform density of consumers and inelastic demand. The pure strategy Nash equilibrium configuration consists of two firms located at one quarter of the ``linear city'', and the other two at three quarters. We do not observe...

This paper deals with the interplay between economic incentives and social norms in firms. We outline a simple model of team production and provide preliminary results on linear incentive schemes in the presence of a social norm that may cause multiple equilibria. The effect of the social norm...
