This book examines key determinants of private sector development in West Africa, putting special emphasis on governments cardinal role in fostering and supporting entrepreneurship. Favorable macroeconomic conditions are identified and it is shown that adequate policies that contribute to economic diversification and industrialization are likely to expand the investment base of the economy. The book also examines new business concepts and regional integration initiatives meant to enhance West Africas private sector and analyzes the role of finance in promoting development of private firms and the extent to which corruption impedes economic growth. All chapters are highly relevant to West Africas current policy challenges and therefore inform the regions ongoing policy formulation. The empirical evidence supporting the policy recommendations is based on both qualitative field observations and advanced quantitative estimation techniques.Introduction.- Part I: Macroeconomic Policy and Private Sector.- Part II: Sectoral Policy and Private Sector.- Part III: Determinants of Private Sector Development.Diery Seck is Director of the Center for Research on Political Economy (CREPOL), based in Dakar, Senegal.
