This paper describes a new cross-country database on the importance of small and medium enterprises (SMEs). This database is unique in that it presents consistent and comparable information on the contribution of the SME sector to total employment and GDP across different countries. The dataset improves on existing publicly available datasets on several grounds. First, it extends coverage to a broader set of developing and industrial economies. Second, it provides information on the contribution of the SME sector using a uniform definition of SMEs across different countries, allowing for consistent cross-country comparisons. Third, while we follow the traditional definition of the SME sector as being part of the formal sector, the new database also includes the size of the SME sector relative to the informal sector. This paper describes the sources and the construction of the different indicators, presents descriptive statistics, and explores correlations with other socioeconomic variables. This paper--a product of Finance, Development Research Group--is part of a larger effort in the group to study SME-related issues.

A New Database

Small and Medium Enterprises Across the Globe

"While substantial research finds that financial development boosts overall economic growth, we study whether financial development disproportionately raises the incomes of the poor and alleviates poverty. Using a broad cross-country sample, we distinguish among competing theoretical predictions about the impact of financial development on changes in income distribution and poverty alleviation. We find that financial development reduces income inequality by disproportionately boosting the incomes of the poor. Countries with better-developed financial intermediaries experience faster declines in measures of both poverty and income inequality. These results are robust to controlling for other country characteristics and potential reverse causality"--National Bureau of Economic Research web site.
