How important are entrepreneurship and management practices in economic development? What measures are effective to support economic development in the global south? Questions like these are in the research focus of David McKenzie, our speaker in the IVWL Research Seminar Economic Behavior and Governance on June 23, 2021. The talk will present findings of a randomized experiment that compares effects of training and consulting for small enterprises to those of supporting these firms in the outsourcing of tasks and the insourcing of competences. The experiment shows the relevance of overcoming the "boundary of the entrepreneur" for firm performance.
