Researchers on variance bounds tests of stock price volatility recognized early that risk aversion can increase the volatility of prices implied by the present-value model. This finding suggests that specifying risk neutrality may induce a bias toward rejecting the present-value model insofar as...

We introduce a form of boundedly-rational expectations into a standard asset-pricing model of the exchange rate, where cross-country interest rate differentials are governed by Taylor-type rules. We postulate that agents augment a lagged-information random walk forecast with a term that relates...

We examine the quantitative implications of government fiscal policy in a discrete-time one-sector growth model with a productive externality that generates social increasing returns to scale. Starting from a laissez-faire economy that exhibits an indeterminate steady state (a sink), we show...

This paper develops a general-equilibrium model of skill-biased technological change that approximates the observed shifts in the shares of wage and non-wage income going to the top decile of U.S. households since 1980. Under realistic assumptions, we find that all agents can benefit from the...

The simplest tests of capital market efficiency are tests of the fair game model: conditional expected returns less the interest rate are equal to zero. The fair game model is thought to obtain only when markets are perfectly liquid. We show that this conjecture is false. In a model of the...
