Within the context of games on networks S. Goyal (Goyal (2007), pg. 39) posed the following problem. Under any arbitrary but fixed topology, does there exist at least one pure Nash equilibrium that exhibits a positive relation between the cardinality of a player's set of neighbors and its...

This paper aims to study the impact of costly and private information acquisition in global games with applications in financial crisis (e.g. bank runs, currency crisis). While exogenous asymmetric information has been shown to select a unique equilibrium, we show that the endogenous costly...

We study a contracting problem in continuous-time where the principal hires an agent to conduct an R&D project for which progress towards success is binary. Under general concave payoffs, we explicitly derive the optimal dynamic incentive con- tract. In the first best scenario where incentives...
