To be successful, reform strategies must be informed by a sound understanding of the diversity of European capitalism and the institutional structures that drive these differences. A common reform approach is to identify a country that appears to be performing well in a particular institutional dimension and to promote this institution in other countries. This kind of best-practice-approach ignores the fact that each country has developed its unique bundle of institutions, which complement each other. Reform strategies that ignore such institutional complementarities risk doing more harm than good. This challenge may explain, for example, why European imitation of policies aimed at stimulating venture capital has been unsuccessful e. Institutions are complementary if the presence or efficiency of one institution increases the returns from or efficiency of the other.
