In this paper, we provide one of the first large sample comparisons of cash policies in public and private US firms. We first show that on average private firms hold less than half as much cash as public firms do. The higher cash holdings of public firms are partially caused by the fact that public firms add more to their cash reserves in a given year, even controlling for a number of spending and savings factors, than do similar private firms. At the same time, however, we find that among firms with excess cash holdings, public firms spend more of it than do private firms. Thus, public firm managers are more aggressive in both accumulating and spending cash reserves. Finally, consistent with the presence of financing frictions, we find that private firms’ cash-to-cash flow sensitivity is higher than that of public firms. Overall, our evidence supports both the agency conflicts and the financing frictions views of corporate cash policy.

Using a sample of Chinese family firms from 2000 to 2007, we investigate whether the political connection of the family firms will help them to reduce the frictions they face in external financing in a relationship-based economy. We find that political connectedness of family firms could reduce their investment-cash flow sensitivity. More interestingly, this political connectedness effect exists only in financially constrained family firms. However, from governance dimension, we cannot find any significant variation of the political connection effect on the sensitivity of investment to cash flow. We argue that these evidences are consistent with the firm’s underinvestment arising from the asymmetric information problems, and are inconsistent with the firm’s overinvestment arising from the free-cash-flow problems.
