The capital structure of a company is the proportion of its assets financed with other people's money, also defined as the proportion of its capitalization financed by long-term debt. Too little debt often means foregoing the tax, monitoring, and other advantages of debt, a less expensive form of capital compared to equity.

Trade-offs like these become more complicated when companies have operations and debt in many countries. Aggarwal has been writing about this topic for many years, and has demonstrated that average levels of debt used by companies differ in various countries in Asia, Europe, and Latin America. Additionally, he has been able to show that this average proportion of corporate debt varies across national borders depending on a number of factors including the level of disclosure timeliness, institutional trading activities, and enforcement of anti-insider trading laws.
