We consider an economy where individuals face uninsurable risks to their human capital accumulation, and study the problem of determining the optimal level of linear taxes on capital and labor income together with the optimal path of the debt level. We show both analytically and numerically that...

We consider an economy where individuals face uninsurable risks to their human capital accumulation, and analyze the optimal level of linear taxes on capital and labor income together with the optimal path of government debt. We show that in the presence of such risks it is beneficial to tax...

How should capital and labor be taxed when individuals' labor income is subject to unin- surable idiosyncratic risks? To address this question, we develop a tractable infinite horizon model with incomplete markets and consider a dynamic optimal taxation problem with linear taxes on the wage and...

At a competitive equilibrium of an incomplete-markets economy agents’ marginal valuations for the tradable assets are equalized ex-ante. We characterize the finest partition of the state space conditional on which this equality holds for any economy. This leads naturally to a necessary and...

A substantial literature addresses the negative eect on welfare of the release of information in a competitive market economy. We show that the value of information in this setting is typically positive if asset markets are suciently incomplete. More specically, for any competitive equilibrium...

This paper develops a general equilibrium, continuous time model where portfolio constraints generate mispricing between redundant securities. Constrained consumption-portfolio optimization techniques are adapted to incorporate redundant, possibly mispriced, securities. We demonstrate the...

This paper examines aggregate savings in a general equilibrium model where infinitely lived households face volatile (and possibly uncertain) income paths, hold a risk-free asset, and face a borrowing constraint. I first show that the equilibrium capital stock in an economy without uncertainty,...

I construct and analyse an example of an economy with production and money under conditions of uncertainty, assymetric information, and an incomplete asset market. For alternative scenarios, which differ in the information available to consumers and firms, I compute the equilibrium prices and...

This introduces the symposium on general equilibrium.
