This paper analyzes a stochastic model of evolution in normal form games. The long-run behavior of individuals in this model is investigated in the limit where mutation rates tend to zero, while the expected number of mutations, and hence population sizes, tend to infinity. It is shown that...

When people share risk in financial markets, intermediaries provide costly enforcement for most trades and, hence, are an integral part of financial markets' organization. We assess the degree of risk sharing that can be achieved through financial markets when enforcement is based on the threat...

In some games, the impact of higher-order uncertainty is very large, implying that present economic theories may be misleading as these theories assume common knowledge of the type structure after specifying the first or the second orders of beliefs. Focusing on normal-form games in which the...

This paper studies the strategic value of delegation in dynamic interactions, where principals provide managers with intertemporal incentives in order to obtain a competitive advantage. While direct management offers intertemporal commitment opportunities, the separation of ownership from...

A (pure) strategy in a repeated game is a mapping from histories, or, more generally, signals, to actions. We view the implementation of such a strategy as a computational procedure and attempt to capture in a formal model the following intuition: as the game proceeds, the amount of information...

Subgame Perfect Correlated Equilibria in Repeated Games by Pavlo Prokopovych and Lones Smith ABSTRACT This paper investigates discounted infinitely repeated games with observable actions extended with an extensive form correlation device. Such games capture situations of repeated interaction of...

Competitive agents extract in continuous time from a commons. Capital market access allows them to both save and borrow against their extraction stream. When the commons asset grows more quickly than the privately stored one, multiple equilibria are found for intermediate commons endowments. One...

Why would a political elite voluntarily dilute its political power by extending the voting franchise? This paper develops a dynamic recursive framework for studying voter enfranchisement. We specify a class of dynamic games in which political rights evolve over time. Each period, private...

This paper formulates a model of dynamic, endogenous reform of political institutions. Specifically, a class of dynamic political games (DPGs) is introduced in which institutional choice is both recursive and instrumental. It is recursive because future political institutions are decided under...

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...
