This research addresses whether geographic diversification provides benefits over industry diversification. In the absence of constraints, no empirical evidence is found to support the argument that country diversification is superior. With short-selling constraints, however, the geographic...

Using a database of more than 180,000 private companies from 2000 to 2009, we find that the benefits of holding more cash vary substantially with a firm's size and the conditions it faces. Cash holdings matter most for small firms: When there are negative shocks to industry or macroeconomic...

Technology choice allows for substitution of production across states of nature and depends on state dependent risk aversion.

We study portfolio choice with multiple stocks and capital gain taxation assuming that capital losses can only offset current or future realized capital gains. We show through backtesting, using empirical distributions, that optimal equity holdings over an extended period are significantly lower...
