Stages of Diversification: France, 1836-1938: "A large literature has documented an association between economic growth and export diversification...:
...We study this question in France between 1836 and 1938. The period witnessed the onset of modern economic growth and sharp changes in the level of international competition. We use a new long term database on French foreign trade at a high level of disaggregation. At the dawn of the first Globalization, France appears to have specialized along Ricardian lines, exporting a handful of textile products in large quantities. There is a decrease in specialization from 1860 to World War I along the lines of modern studies. Changes in trade costs along with economic growth help explain the evolution of France’s comparative advantage. The decline of export concentration is associated with a chronic deficit in the balance of trade during the Belle Époque and the major part of the interwar period particularly after 1927.
