Differences in management quality are an important contributor to productivity differences across countries. A key question is how to best improve poor management in developing countries. This paper tests two different approaches to improving management in Colombian auto parts firms. The first...

Small trading activities are a prevalent form of self-employment in developing countries, but their integration into supply value chains is not efficient, especially when it comes to perishable produce. This study tests a novel approach to improve their efficiency by reducing the time and cost...
