In repeated normal-form games, simple penal codes (Abreu 1986, 1988) permit an elegant characterization of the set of subgame-perfect outcomes. We show that the logic of simple penal codes fails in repeated extensive-form games. We provide two examples illustrating that a subgame-perfect outcome...

Do large investors increase the vulnerability of a country to speculative attacks in the foreign exchange markets? To address this issue, we build a model of currency crises where a single large investor and a continuum of small investors independently decide whether to attack a currency based...

We analyze incentives to develop entrepreneurial ideas for venture capitalists (VCs) and incumbent firms. If VCs are sufficiently better at judging an idea's value and if it is sufficiently more costly to patent low than high value ideas, VCs acquire valuable ideas, develop them beyond the level...

We investigate the outcome of bargaining when a player’s pay-off from agreement is risky. We find that a risk-averse player typically increases his equilibrium receipts when his pay-off is made risky. This is because the presence of risk makes individuals behave 'more patiently' in bargaining....

In this paper we characterize a situation in which non-calculative trust has to play a role in the decision to cooperate. We then analyse the given situation in game theoretical terms and distinguish those aspects of players’ decisions that are cooperative from those that may be interpreted as...

We experimentally examine the effects of flexible and fixed prices in markets for experience goods in which demand is driven by trust. With flexible prices, we observe low prices and high quality in competitive (oligopolistic) markets, and high prices coupled with low quality in non-competitive...

In an observational learning environment, rational agents with incomplete information may mimic the actions of their predecessors even when their own signal suggests the opposite. This herding behaviour may lead the society to an inefficient outcome if the signals of the early movers happen to...

We examine a model in which the public is unsure about the competence of a politician, and whether they are concerned about the long-term consequences of their decisions (statesman) or about the public’s opinion concerning their competence and preferences (populist). The main finding suggests...

We consider a network game with strategic complementarities where the individual reward or the strength of interactions is only partially known by the agents. Players receive different correlated signals and they make inferences about other players' information. We demonstrate that there exists...

We consider a frictional two-sided matching market in which one side uses public cheap-talk announcements so as to attract the other side. We show that if the first-price auction is adopted as the trading protocol, then cheap talk can be perfectly informative, and the resulting market outcome is...
