Policy makers have developed different forms of policy intervention for stopping,

I present a political-economic theory to explain bailouts for failing firms in the
presence of non-voters (foreigners). The governing politician uses the bailout as
a tool to sway voters to maximize re-election chances. Bailouts partially leak to

We study financial markets in which both rational and overconfident agents coexist and make endogenous information acquisition decisions. We demonstrate the following irrelevance result: when a positive fraction of rational agents (endogenously) decides to become informed in equilibrium, prices are...

We study a novel class of noisy rational expectations equilibria in markets with large number of agents. We show that, as long as noise (liquidity traders, endowment shocks) increases with the number of agents in the economy, the limiting competitive...

This paper considers an optimal contracting problem between an informed risk-averse agent and a principal, when the agent needs to perform multiple tasks, and the principal is active, namely she can influence some aspect of the agency relationship on top...

We develop a benchmark model to study the equilibrium consequences of indexing in a standard rational expectations setting. Individuals incur costs to participate in financial markets, and these costs are lower for individuals who restrict themselves to indexing. A decline...
