The serious threat of the underdeveloped areas of the Common Market, particularly southern Italy and certain regions of France, to European unity is considered and constructive means to alleviate this danger are presented. A careful analysis is made of the regional economies of the underdeveloped areas. In each case the forms of cooperation developing between these governments and the institutions of the European Economic Community are drawn, and an assessment is made of the jeopardy to the areas if proper action is not taken. Originally published in 1965. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
