Micro and small enterprises (MSEs) have been recognised as a major contemporary source of employment and income in a growing number of developing countries. Yet, relatively little is known about the characteristics and patterns of change in these enterprises. This volume examines the dynamics of MSEs in the development process. Drawing on a set of surveys conducted in 12 countries in Africa and Latin America the authors map the patterns of change in MSEs in the developing world. Subjects covered include: significance of new start and closure rates of MSEs; factors involved in expansion rates and growth patterns of MSEs; and the role of gender in MSEs revolution. The text also develops a four-fold characterization of MSEs, from which follows a reflection in the problems faced by and the diverse needs of MSEs. The authors conclude by drawing important lessons for donors and implementing agencies, based on the need to tailor policy to the varying contributions to development and needs of different MSEs. In its presentation of real-life examples and its suggestions for improving development assistance efforts, this volume should be welcome by students and researchers in development eco
