We show that, when allowing for general distributions of dividend growth in a Lucas economy with multiple "trees," idiosyncratic volatility will affect expected returns in ways that are not captured by the log linear approximation. We derive an exact expression for the risk premia for general...

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...

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...

We explore the relation between institutional quality, trust and stock-market participation. In our theoretical model, agents update their beliefs in a Bayesian manner based on observations on frauds and choose whether to invest in the stock market. The corresponding empirical model shows that...

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. In addition, the model produces an implied pricing kernel that is increasing for particular levels...

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. We test our model using GMM and compare it to the CAPM. The results suggest that adding an...

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, we show that - if cost functions are convex and the assets have identical return...

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 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

This paper analyzes the term structure of interest rates in an exchange-only Lucas (Econometrica 46:1429–1445, <CitationRef CitationID="CR32">1978</CitationRef>) economy where consumers learn about a stochastic growth rate through observations of the endowment process and an external public signal. We allow for deluded consumers, who...</citationref>
