This paper analyzes the expected life-time utility and the hedging demands in a Lucas (1978) economy, in which the dividend drift term is unknown and mean-reverting. An expression for the individual investor’s expected life-time utility in equilibrium is derived, and his hedging demand is...

This paper investigates the extent to which differences in information costs can explain the equity home bias puzzle. In a model where information costs are higher for the Foreign asset than for the Home asset, I show that, if cost functions are convex and the assets have identical return...

This paper studies the pricing of IPOs in a tractable model in which an investment bank faces some investors with superior information. We show how this can lead to underpricing and we make a number of empirical predictions.

We show that a simple equilibrium model with uncertain growth is able to simultaneously generate patterns in implied volatility and risk aversion that are similar to the ones observed in the data.

We analyze how a benevolent, privately-informed government agency would optimally release information about the economy's growth rate when the agents hold heterogeneous beliefs. We model two types of agents: "trusting" and "distrustful." The former has a prior that is identical to that of the...

This paper analyzes the expected life-time utility and the hedging demands in an exchange only, representative agent general equilibrium under incomplete information. We derive an expression for the investor’s expected life-time utility, and analyze his hedging demands for intertemporal...

Three types of agents acting on different information sets are considered: fully informed agents, insiders, and outsiders. Differences in information quality are shown to affect the properties of their optimal portfolios. For an outsider, the share of wealth invested in the stock is decreasing...

This paper analyzes the term structure of interest rates in an exchangeonly Lucas (1978) economy where consumers learn about a stochastic growth rate through observations of the endowment process and an external public signal. We show that there is a premium for noisy external public information...

This paper analyzes the expected life-time utility and the hedging demands in an exchange only, representative agent general equilibrium under incomplete information. We derive an expression for the investor's expected life-time utility, and analyze his hedging demands for intertemporal changes...

We show in a theoretical model that the expected excess return on any asset depends on its covariance not only with the market portfolio, but also with changes in the representative agent’s estimate. In the empirical specification, this ”estimation factor” is based on realized growth in...
