The authors investigate whether integration with global markets affects the financing choices of firms from East Asia and Latin America. Using firm-level data for the 1980s and 1990s, they study how leverage ratios, the structure of debt maturity, and sources of financing change when economies are liberalized and when firms gain access to international equity and bond markets. The evidence shows that integration with world financial markets has uneven effects. On the one hand, debt maturity for the average firm shortens when countries undertake financial liberalization. On the other hand, domestic firms that actually participate in international markets, get better financing opportunities, and extend their debt maturity. Moreover, firms in economies with deeper domestic financial systems are affected less by financial liberalization. Finally, they show that leverage ratios increase during times of crisis. In an appendix, they analyze the previously unstudied case of Argentina, which experienced sharp financial liberalization, and was hit hard by all recent global crises.
