Firms facing significant business risks have incentives to mitigate the costs of these risks by adjusting their capital structures. This paper investigates this link by analyzing the exposures of multinational firms to political risk. The evidence indicates that returns on investment in politically risky countries are more volatile than returns elsewhere. Multinational firms reduce their leverage in response to these political risks: a one standard deviation increase in foreign political risk is associated with 3.5% reduced leverage. The effect of foreign political risks on leverage is most pronounced for firms in industries whose returns are most susceptible to political influence.

This paper analyzes the determinants of partial ownership of the foreign affiliates of U.S. multinational firms and, in particular, the marked decline in the use of joint ventures over the last 20 years. The evidence indicates that whole ownership is most common when firms coordinate integrated production activities across different locations, transfer technology, and benefit from worldwide tax planning. Because operations and ownership levels are jointly determined, it is helpful to use the liberalization of ownership restrictions by host countries and the imposition of joint venture tax penalties in the U.S. Tax Reform Act of 1986 as instruments for ownership levels to identify these effects. Firms responded to these regulatory and tax changes by using wholly owned affiliates instead of joint ventures and expanding intrafirm trade and technology transfer. The implied complementarity of whole ownership and intrafirm trade suggests that the reduced costs of engaging in integrated global operations contributed substantially to the sharply declining propensity of American firms to organize their foreign operations as joint ventures over the last two decades. Estimates imply that as much as one-fifth to three-fifths of the decline in the use of joint ventures by multinational firms is attributable to the increased importance of intrafirm transactions. The forces of globalization appear to have diminished, rather than accelerated, the use of shared ownership.

US corporations hold significant amounts of cash on their balance sheets. This paper develops and tests the hypothesis that the magnitude of US multinational cash holdings are, in part, a consequence of the tax costs associated with repatriating foreign income. Consistent with this hypothesis, firms facing higher repatriation taxes hold higher levels of cash, hold this cash abroad, and hold this cash in affiliates that trigger high tax costs when repatriating earnings. In addition, less financially constrained firms and those that are more technology intensive exhibit a higher sensitivity of affiliate cash holdings to repatriation tax burdens.
