Movements in the prices of different assets are likely to directly influence one another. This paper identifies the contemporaneous interactions between asset prices in U.S. financial markets by relying on the heteroskedasticity in their movements. In particular, we estimate a "structural-form...

This paper constructs a simple dynamic asset pricing model which incorporates recent evidence on the influence of immediate emotions on risk preferences. Investors derive direct utility from both consumption and financial wealth and, consistent with the happiness maintenance feature documented...

I study a labor market in which identical workers search on- and off-the-job and heterogeneous firms employ using either posted wages or wage contracts contingent on outside options. Firm level costs for contingent contracts generate a separating equilibrium in which less productive firms post...

We identify the relative importance of changes in the conditional variance of fundamentals (which we call "uncertainty") and changes in risk aversion ("risk" for short) in the determination of the term structure, equity prices, and risk premiums. Theoretically, we introduce persistent...

In this note we delineate conditions under which continuous time stochastic processes can be identified from discrete data. The identification problem is approached in a novel way. The distribution of the observed stochastic process is expressed as the underlying true distribution, f,...

Estimating the response of asset prices to changes in monetary policy is complicated by the endogeneity of policy decisions and the fact that both interest rates and asset prices react to numerous other variables. This paper develops a new estimator that is based on the heteroskedasticity that...

We investigate the effects of U.S. monetary policy on asset prices using a high-frequency event-study analysis. We test whether these effects are adequately captured by a single factor--changes in the federal funds rate target-and find that they are not. Instead, we find that two factors are...
