An important question in international finance is to what extent stock return volatility is influenced by country location, industry affiliation, and global factors. This Paper develops a new methodology to measure these effects, in which portfolios mimicking ‘pure’ country and industry...

This paper presents new stylized facts on the distribution of the home bias at the fund level. We find (i) a large heterogeneity in the degree of home bias across mutual funds; (ii) a positive correlation between the size of funds and home bias; and (iii) a positive correlation between the size...

Our objective in this paper is to examine whether one can use option-implied information to improve mean-variance portfolio selection with a large number of stocks, and to document which aspects of option-implied information are most useful for improving the out-of-sample performance of...

How to evaluate a fund manager’s skill is a central question in empirical finance. Prior literature has defined skill as an ability to either pick stocks or time the market, at all times. We propose a new definition of skill as a general cognitive ability used in different ways at different...

We show that international consumption risk sharing is significantly improved by capital flows, especially portfolio investment. Concomitantly, we show that poor institutions hamper risk sharing, but to an extent that decreases with openness. In particular, risk sharing is prevalent even among...

Using a new dataset on capital account openness, we investigate why equity return correlations changed over the last century. Based on a new, long-run dataset on capital account regulations in a group of 16 countries over the period 1890-2001, we show that correlations increase as financial...
