This paper studies oligopolistic firms’ exploitation of a renewable natural resource in a differential game. It is well known that finding Markov perfect equilibrium in differential games is extremely difficult except for games that are linear-quadratic. In this paper, we develop a...

In this paper, an infinitely-repeated Bertrand game is considered. The model has a two-tier relationship; two firms make a self-enforced collusive agreement and each firm writes a law-enforced contract to its privately-informed agent. The main finding is that in optimal collusion, interaction...

For an N players coordination games, Tanaka (2000) proved that the notion of N/2 stability defined by Schaffer (1988) is a necessary and sufficient condition for long run equilibrium in an evolutionary process with mutations (in the sense of Kandori, et. al. (1993)). We argue that the critical...

The paper studies equilibrium selection in supermodular games based on a class of perfect foresight dynamics, introduced by Matsui and Matsuyama (JET 1995) and further developed by Hofbauer and Sorger (JET 1999, IGTR 2002) and Oyama (JET 2002). A normal form game is played repeatedly in a large...

It is well known that in a two stage duopoly model of product choice with quadratic transportation cost, the firms locate at the extreme endpoints of the market. This paper examines this model in an infinite horizon setting where in the initial period the firms choose locations and in subsequent...

Specialist merchants and traders---agents who mediate the transfer of goods and services between producers and consumers---are central to the economic process, but there are few theoretical models in which the institution of intermediation is an endogenous part of an equilibrium. This paper...

This paper analyzes bidding behavior in a multi period multiple unit auction. While bidders are ex ante symmetric, the first period outcome translates the second period game to a game between asymmetric bidders. The first period outcome determines who will be a strong or a weak bidder in the...

Can advertising lead to a sustainable competitive advantage? To answer this question, we propose a dynamic model of advertising competition where firms repeatedly advertise, compete in the product market, and make entry as well as exit decisions. Within this dynamic framework, we study two...
