Institutional investors usually employ mean-variance analysis to determine optimal portfolio weights. Almost immediately upon implementation, however, the portfolio's weights become sub-optimal as changes in asset prices cause the portfolio to drift away from the optimal targets. In an idealized...

We study the comovement among stock prices and among exchange rates in a three-good three-country Center-Periphery dynamic equilibrium model in which the Center's agents face portfolio constraints.We characterize equilibrium in closed form for a broad class of portfolio constraints, solving for...

The paper presents a framework for analyzing the degree of financial transmission between money, bond and equity markets and exchange rates within and between the United States and the euro area. We find that asset prices react strongest to other domestic asset price shocks, and that there are...

This paper measures the effects of the risks associated with the war in Iraq on various U.S. financial variables using a heteroskedasticity-based estimation technique. The results indicate that increases in what we call the quot;war riskquot; factor caused declines in Treasury yields and equity...

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...

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...

Movements in the stock market can have a significant impact on the macroeconomy and are therefore likely to be an important factor in the determination of monetary policy. However, little is known about the magnitude of the Federal Reserve's reaction to the stock market. One reason is that it is...

We study the implications of introducing demand shocks and trade in goods into an otherwise standard international asset pricing model. Trade in goods gives rise to an additional channel of international propagationmdash;through the terms of trademdash;absent in traditional single-good models....
