We study the effects of a social security reform in a large overlapping generations model where markets are incomplete and households face uninsurable idiosyncratic income shocks. We depart from the previous literature by assuming that, because of lack of commitment in the credit market, the...

Many recent papers in macroeconomics have studied the implications of models with household heterogeneity and incomplete financial markets under the assumption that households own the stock of physical capital and undertake the intertemporal investment decisions. In these models, production...

We study the effect of borrowing limits on welfare in several versions of exchange and production economies. There is a "quantity" effect of a larger borrowing limit which is beneficial for liquidity constrained agents, but essentially irrelevant otherwise. There is also a ``price effect" which...

This paper analyzes the welfare costs of business cycles when workers face uninsurable idiosyncratic labor income risk. In accordance with the previous literature, this paper decomposes labor income risk into an aggregate and an idiosyncratic component, but in contrast to the previous...

Although equilibrium allocations in models with incomplete markets are generally not Pareto-efficient, it is often argued that quantitative welfare losses from missing assets are small when time horizons are long and shocks are transitory. In this paper, we use a computational analysis to show...

This paper augments the neoclassical growth model to study the macroeconomic effects of uninsured idiosyncratic investment, or capital-income, risk. Under standard assumptions for preferences and technologies, individual policy rules are linear in individual wealth, ensuring that the equilibrium...

I study the asset pricing implications and the efficiency of a tractable dynamic stochastic general equilibrium model with heterogeneous agents and incomplete markets along the lines of Krebs [Krebs, T., 2003. Human Capital Risk and Economic Growth. Quarterly Journal of Economics 118(2),...

In this paper, we study the quantitative implications of a real business cycle model where the firm is the capital owner, households are heterogeneous, and markets are incomplete due to restricted asset trade. Since, under these assumptions, the usual firm objective is no longer well defined,...

In a Bewley model with endogenous price volatility, home ownership and mobility across locations and jobs, we assess the contribution of financial constraints, housing illiquidities and house price risk to home ownership over the life cycle. The model can explain the rise in home ownership and...

This paper studies the effects of financial policy in a model with heterogeneous agents, incomplete markets and portfolio restrictions. For an economy calibrated to replicate key aspects of the US wealth distribution, we find that the quantitative effects of financial policy are relatively...
