This course intends to introduce the students to the diversity of organizational arrangements in modern market economies. In a certain sense it can be viewed as a deep remodeling of the traditional microeconomic perspective. Problems of coordination and incentives as well as the trade-off among alternative modes of organization will be at the core of the analysis. Insights on problems of innovation will also be on the agenda. Although the course requires a basic understanding of the fundamental tools of economics, the orientation is not technical but rather focuses on issues at stake. The goal is to provide students with a coherent vision of the diverse organizational arrangements that structure economic activities of production and exchange in an increasingly globalized environment.
