The dynamics of micro and small enterprises in developing countries

The number of people engaged in micro and small enterprises increases as a result of new enterprises being started and through an expansion of existing activities. As a partial offset to these increases, employment declines when existing businesses cease operations. This article draws on recent survey work to examine the magnitude and determinants of enterprise births, closures and expansions. It explores the ways in which these different sources of change are influenced by the state of the macroeconomy, and examines policy and project implications.
