with Ross Levine, Sergio L. Schmukler: w20336
Which firms issue equity and debt in domestic and international markets and what happens to their assets, sales, and number of employees? To answer these questions, we assemble a new dataset on firm-level capital raising activity during 1991-2011, which we match with firm attributes for 45,527 listed firms from 51 economies during 2003-2011.

The number of holdings in stocks and countries from a given region declines as the investment scope of funds broadens. This restrictive investment practice has costs. A mean-variance strategy shows unexploited gains from further international diversification. Mutual funds investing globally could achieve better risk-adjusted returns by broadening their asset allocation, including stocks held by more specialized funds within the same mutual fund family (company). This investment pattern is not explained ...
