When agents face no aggregate risk, there is … of idiosyncratic and aggregate risk. In the case of exponential (isoelastic) utility, cooperation depends positively on …

The relationship between trust and risk is a topic of enduring interest. Although there are substantial differences … in the widely-used "trust game" actually measure trust, or instead reveal more about risk attitudes.

Early results of evolutionary game theory showed that the risk dominant equilibrium is uniquely selected in the long … nonbest response is state-dependent. This paper shows that the unique selection of the risk dominant equilibrium is robust … exists a minimum population size beyond which the risk dominant equilibrium is uniquely selected.

Can the risk of losses upon premature liquidation produce bank runs? We show how a unique run equilibrium driven by … asset liquidity risk arises even under minimal fundamental risk. To study the role of illiquidity we introduce realistic … not available in a run, asset liquidity risk has a concave effect on run incentives, quite unlike fundamental risk. Runs …
