Applications of institutional analysis to the explanation of economic performance come in many flavors. Some economists have made use of an economics-oriented flavor in treating culture as one component of that analysis. Steven Heydemann uses a more political flavor of institutional analysis to argue that two of these economists, Douglass North and Avner Greif, have overly simplified and homogenized the concept of culture and the way in which it affects economic performance. He goes on to identify several instances in both the economic history and contemporary experience of the Middle East where he claims that such oversimplification has led to shortcomings in the analysis. This paper suggests that while some of Heydemann's claims have merit, several others are exaggerated.
