This book attempts to address these issues from an economic perspective. Combining knowledge and field experience, it develops an analysis of institutional changes and organizational transformations based on the experience of the public procurement reforms carried out in sub-Saharan Africa. This highlights the economic significance of procurement and the formidable obstacles that institutional changes face. Using an original dataset, it explores the gap between the expectations and what has been achieved. It develops a framework that intends to capture the complex interaction between the different components of reform and aims to provide useful insights for researchers and policy makers.
