We introduce the notion of a stone age equilibrium to study societies in which property rights are absent, bilateral exchange is either coercive or voluntary, and relative strength governs power relations in coercive exchange. We stress the importance of free disposal of goods which allows for...

We analyze maximal cartel prices in infinitely-repeated oligopoly models under leniency where fines are linked to illegal gains, as often outlined in existing antitrust regulation, and detection probabilities depend on the degree of collusion. We introduce cartel culture that describes how...

Unique-lowest sealed-bid auctions are auctions in which participation is endogenous and the winning bid is the lowest bid among all unique bids. Such auctions admit very many Nash equilibria (NEs) in pure and mixed strategies. The two-bidders' auction is similar to the Hawk-Dove game, which...

We study a bargaining model with a disagreement game between offers and counteroffers. In order to characterize the set of its subgame perfect equilibrium payoffs, we provide a recursive technique that relies on the Pareto frontier of equilibrium payoffs. When players have different time...

For a general class of oligopoly models with price competition, we analyze the impact of ex-ante leniency programs in antitrust regulation on the endogenous maximal-sustainable cartel price. This impact depends upon industry characteristics including its cartel culture. Our analysis disentangles...

This contribution deals with the fundamental critique in Dinar et al. (1992, Theory and Decision 32) on the use of Game theory in water management: People are reluctant to monetary transfers unrelated to water prices and game theoretic solutions impose a computational burden. For the bilateral...

There has been a long debate on equilibrium characterization in the negotiation model when players have different time preferences. We show that players behave quite differently under different time preferences than under common time preferences. Conventional analysis in this literature relies...

Short-term contracts and exogenous productivity growth are introduced in a simple wage bargaining model. The equilibrium utilities corresponding to militant union behaviour are independent of the contract length. The wage dynamics are linear if strike is credible (low wage shares) and nonlinear...

We extend the standard evolutionary model of Kandori, Mailath, and Rob (1993) to incorporate time-varying aggregate and idiosyncratic shocks separately in coordination games. We show that both types of shocks have a different effect on the invariant distribution over the different equilibria of...

In this paper the behavior of producers in a social environment is considered from a more sociological point of view than is usually done in economics. The producers play Bertrand price competition against each other and change the action they played based upon the outcome of the game, according...
