Traditional asset pricing models predict that covariance between prices of different assets should be lower than what we observe in the data. This model generates this high covariance within a rational expectations framework by introducing markets for information about asset payoffs.(...)

In a model with housing collateral, the ratio of housing wealth to total wealth shifts the conditional distribution of asset prices and consumption growth. A decrease in house prices reduces the collateral value of housing, increases household exposure to idiosyncratic risk, and increases the...

We investigate a consumption-based present value relation that is a function of future dividend growth. Using data on aggregate consumption and measures of the dividend payments from aggregate wealth, we show that changing forecasts of dividend growth are an important feature of the post-war...

We provide the impact on asset prices of search-and-bargaining frictions in over-the-counter markets. Under natural conditions, prices are lower and illiquidity discounts higher when counterparties are harder to find, when sellers have less bargaining power, when the fraction of qualified owners...

Time-variation in the degree of risk-sharing induced by changes in the value of housing collateral sheds new light on the consumption correlation puzzle.(...)

Emerging equity markets witness occasional surges in the price level (frenzies) and increases in cross-market price dispersion (herds), accompanied by a flood of media coverage. Complementarity in information acquisition can explain these anomalies.(...)

As risk aversion approaches infinity, the portfolio of an investor with utility over consumption at time T is shown to converge to the portfolio consisting entirely of a bond maturing at time T. Previous work on bond allocation requires a specific model for equities, the term structure, and the...

There is an ongoing debate in the literature about the apparent weak or negative relation between risk (conditional variance) and return (expected returns) in the aggregate stock market. We develop and estimate an empirical model based on the ICAPM to investigate this relation.(...)

This paper proposes a habit formation model that explains the failure of the expectations hypothesis documented by Campbell and Shiller (1991) and Fama and Bliss (1987).(...)

We study the impact on asset prices of illiquidity associated with search and bargaining in an economy in which agents can trade only when they find each other. Marketmakers' prices are higher and bid-ask spreads are lower if investors can find each other more easily. (...)
