We here develop a model of pre-play communication that generalizes the cheap-talk approach by allowing players to have a lexicographic preference, second to the payoffs in the underlying game, for honesty. We formalize this by way of an honesty (or truth) correspondence between actions and...

Equilibrium paths in economies of overlapping generations depend on the frequency of trade. In a logarithmic example, determinacy obtains as the frequency of trades tends to infinity or trade occurs in continuous time. If time extends infinitely into the infinite past as well as into the...

Perfect information games have a particularly simple structure of equilibria in the associated normal form. For generic such games each of the finitely many connected components of Nash equilibria is contractible. For every perfect information game there is a unique connected and contractible...

We show that in long repeated games, or in infinitely repeated games with discount rate close to one, payoffs corresponding to evolutionary stable sets are asymptotically efficient, as intuition suggests. Actions played at the beginning of the game are used as messages that allow players to...

Common wisdom about the effects of gas market liberalization in the EU claims that the fragmentation of gas supply in the downstream market can raise the price of gas imports, as the bargaining power of European firms in the upstream market would be weakened. We consider such a claim from the...

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...

This paper analyzes the interplay between economic incentives and social norms in a public finance context. We assume that to live off one's own work is a social norm, and that the larger the population fraction adhering to this norm, the more intensely it is felt by the individual. It is shown...

How much and when should we limit economic and social activity to ensure that the health-care system is not overwhelmed during an epidemic? We study a setting where ICU resources are constrained while suppression is costly (e.g., limiting economic interaction). Providing a fully analytical...

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...

We analyze investment decisions when information is costly, with and without delegation to an agent. We use a rational-inattention model and compare it with a canonical signal-extraction model. We identify three "investment conditions". In "sour" conditions, no information is acquired and no...
