The empirical challenge is that observing domestic and foreign cash historically has not been possible using publicly available data sources. While some firms recently have voluntarily disclosed their foreign cash position (Harford, Wang, and Zhang 2017), this selectively released data is limited in both scope and length. The Bureau of Economic Analysis (BEA) conducts a mandatory survey of U.S. multinational companies that generates the data that is needed to address this short coming. From this survey, we are able to measure the amount of cash and marketable securities that firms are holding in each foreign subsidiary. Combining this with the disclosure of their total cash and marketable securities position (from Compustat), we are able to calculate how much cash is held domestically.
