A large body of literature has found that in countries with weak institutions firms are able to obtain less external financing, resulting in lower growth. Indeed, even simple cross-country comparisons of firm financing patterns can be quite revealing. In a paper co-authored with Thorsten Beck and Vojislav Maksimovic, this is exactly what we do. Using data from the World Bank’s Enterprise Surveys dataset (WBES) for 48 countries, we investigate what proportion of firm investment is financed externally, and, of this external finance, how much of it comes from different sources, such as bank and equity finance, leasing, supplier credit, development banks, and informal sources such as money lenders.
In our sample of firms, on average just over 40 percent of firm investment is externally financed. Breaking external financing down into its parts, about 19 percent of all financing comes from commercial banks and 3 percent from development banks. Another 7 percent is provided by suppliers and 6 percent through equity investment. Leasing is another 3 percent, and less than 2 percent comes from informal sources. More recent enterprise survey data for an expanded sample of countries and firms also suggest similar patterns (Figure 1).
