We study housing and debt in a quantitative general equilibrium model. In the cross-section, the model matches the wealth distribution, the age profiles of homeownership and mortgage debt, and the frequency of housing adjustment. In the time-series, the model matches the procyclicality and...

We study empirical mean-variance optimization when the portfolio weights are restricted to be direct functions of underlying stock characteristics such as value and momentum. The closed-form solution to the portfolio weights estimator shows that the portfolio problem in this case reduces to a...

The expansion in financial sector "safe" assets, largely in the form of structured products from the U.S. and the Caribbean, in the lead-up to the global financial crisis has by now been fairly well documented. Using a unique dataset derived from security-level data on U.S. portfolio holdings of...

Do more active hedge fund managers generate higher returns than their less active peers? We attempt to answer this question. Using Kalman Filter techniques, we estimate the risk exposure dynamics of a large sample of live and dead equity long-short hedge funds. These estimates are then used to...

I study long-short portfolio strategies formed on seven different stock characteristics representing various measures of past returns, value, and size. Each individual characteristic results in a profitable portfolio strategy, but these single-characteristic strategies are all dominated by a...

In this paper I explore the role of portfolio diversification in explaining the distribution of foreign investment across countries. I capture the portfolio diversification motive by a measure of country-specific riskiness, “covariance risk,” which I construct as how countries' growth rates...

We analyze how interest rates affect cross-border portfolio investments. Data on U.S. bond holdings by foreign investors from 31 countries for the period 2003 - 2016 and a large variety in movements in interest rates in these countries provide for a unique way to analyze shifts in investment...

The risk-taking effects of low interest rates, now prevailing in many advanced countries, "search-for-yield," can be hard to analyze due to both a paucity of data and challenges in identification. Unique, security-level data on portfolio investment into the United States allow us to overcome...

How does sovereign risk affect investors' behavior? We answer this question using a novel database that combines sovereign default probabilities for 27 developed and emerging markets with monthly data on the portfolios of individual bond mutual funds. We first show that changes in yields do not...
