Researchers in CEPR's research project on `Comparative Experience of Economic Growth in Postwar Europe' took part in a Country Studies Workshop, held in Madrid on 16/17 October and organized by Nicholas Crafts, Professor of Economic History at the University of Warwick and Research Fellow in CEPR's Human Resources programme, and Leandro Prados de la Escosura, Professor of Economics at Universidad Carlos III, Madrid. Participants focused on the implications for individual country studies of theoretical advances in identifying the key components of growth, the application of `new growth theory' to reinterpret post-war European experience, the contributions of catch-up and convergence to growth differentials, the relationship of growth with European integration, and the effects of specific institutions and policies on technology transfer and factor accumulation. They also considered recent statistical work on the growth of total factor productivity and intensity, comparative productivity relative to the US, R&D and human capital formation, subsidies, taxes and tariffs, industrial relations, capital markets and the external sector.
