This paper examines the quantitative relationship between the elasticity of capital-labor substitution and the conditions needed for equilibrium indeterminacy (and belief-driven fluctuations) in a one-sector neoclassical growth model. Our analysis employs a “normalized” version of the CES...

This paper develops a stochastic endogenous growth model that exhibits “excess volatility” of equity prices because speculative agents overreact to observed technology shocks. When making forecasts about the future, speculative agents behave like rational agents with very low risk aversion....

We investigate the behavior of the equilibrium price-rent ratio for housing in a standard asset pricing model. We allow for time-varying risk aversion (via external habit formation) and time-varying persistence and volatility in the stochastic process for rent growth, consistent with U.S. data...

Engel (2005) derives a theoretical variance inequality involving the change in equilibrium stock prices Var ( p) : Assuming that stock prices are "cum-dividend" and that investors are risk neutral, he shows that Var ( p) must be greater than or equal to the variance of the "perfect foresight"...

This paper investigates how concentrated ownership of capital influences the pricing of risky assets in a production economy. The model is designed to approximate the skewed distribution of wealth and income in U.S. data. I show that concentrated ownership significantly magnifies the equity risk...

We show that the steady-state optimal tax on capital income can be negative, positive, or zero in a neoclassical growth model that allows for imperfectly competitive product markets. The sign of the optimal tax rate depends crucially on (1) the degree of monopoly power, (2) the extent to which...
