Does the presence of institutional hybridization invariably lead to lower rates of economic growth? The absence of tight complementarities between the different spheres of the economy makes it harder for companies to secure market-based or strategic- inspired modes of coordination. I investigate this issue with the case of France - an institutionally hybrid economy whose relative economic performance has declined in the last decade. I highlight that the prominence of state intervention in the first four postwar decades lessened the weaknesses of institutional hybridization. Nonetheless, state dirigisme did not eliminate the shortcomings associated with a hybrid model. If anything, state intervention in France significantly contributed to stifle the development of institutional capacities of actors, most notably labour organisations, which are crucial in coordinated market economies
