EU and non EU Export performance of Italian firms. Is there an industrial district effect

Geographical agglomeration of productive units is expected to affect positively cooperation in "multiple winners" games in which costs from increased neighbour competition are not too high. Small-medium firm export activity is a typical game with these features. Economies of scale in the provision of export services and informal face-to\uad face exchanges of information about export markets may in fact facilitate participation to export activity without threatening potential profits due to productive capacity constraints and the large scale of the market. The current paper carries an empirical test and finds that geographical agglomeration of small-medium firms in a delimited area significantly affects their export intensity and their probability of becoming exporters. The effect is stronger far exports towards non EU markets and is negatively related to firm size. The significance of geographical agglomeration persists in spite of all controls included in the estimate which show how the dependent variable is also (positively) affected by export subsidies, formal export cooperation among firms, size and age. Paper results suggest that geographical agglomeration, by shifting firms from domestic to foreign markets, may then be - if technological benefits from more competition are relatively higher on foreign markets - an important engine for endogenous growth in a downsized system, such as Italy, with a strong specialisation in Traditional and Specialised sectors
