During the 1950's, Fiat, one of Italy's most important manufacturing companies, grew at enormous speed. Two factors helped the car maker achieve this impressive performance: For one, a set of import barriers virtually denied foreign producers access to the Italian market until the founding of the European Economic Community (EEC). Moreover, Fiat managed to remain at the cutting edge of car manufacturing technology, enabling it to expand production, foreign sales and profits. Combining a reliance on trade barriers with technological change as well as an aggressive export strategy, Vittorio Valletta, Fiat's post-World War II general manager, bet on serving the more dynamic foreign markets from modern plants built with the help of Marshall Plan funds. From this basis he later sold into a growing domestic market, where Fiat was without serious competition.
