This paper uses the framework of an OLG economy with three-period lived agents in which a durable good serves as collateral for loans, to study the effect of an unanticipated income shock when the economy is in a steady state equilibrium. We focus on the consequence of default on loans when the...

This paper studies a general equilibrium model with two groups of agents, investors (shareholders) and managers of firms, in which managerial effort is not observable and influences the probabilities of firms' outcomes. Shareholders of each firm offer the manager an incentive contract which...

This paper studies qualitative properties of an optimal contract in a multi-agent setting in which agents are subject to a common shock. We derive a necessary and sufficient condition for the optimal reward of an agent producing an output level y to be a decreasing (increasing) function of the...

Stock market price/earnings ratios should be influenced by demography. Since demography is predictable, stock returns should be as well. We provide a simple stochastic OLG model with a cyclical structure which generates cyclical P/E ratios. We calibrate the model to roughly fit the cyclical...

This paper presents a simple model of banking equilibrium in which unconventional monetary policy serves as a tool to enhance the safety of the banking system. Every economy has two intrinsic characteristics: a "natural" debt-equity ratio which depends on the endowments of the infinitely risk...

This paper studies a simple OLG model with production under the assumption that capital investment is completely irreversible: installed capital cannot be transformed back into consumption good nor transferred from one firm to another. Since firms cannot be dismantled at each generational change...
