Originally published in 1988, this study focusses on international economic integration in relation to the passenger car industry and market in the West-European car-making countries, Germany, France, Italy, Sweden and the UK in the second half of the 20^th Century when the revival of protectionism was a key feature of the international trading system. The book illustrates the interaction between international integration, market structure and firm conduct and the political sphere at the national as well as the supranational level. Unlike previous analyses of international integration, this book concentrates on a single industry over a significant period.
