The paper is in collaboration with Alessia Amighini and Marinella Leone.

It investigates the evolution of specialization patterns for the Italian provinces over the period 1995-2005 by analysing the dynamics of the sectoral distribution in the Balassa index of revealed comparative advantages. The results show that underlying a relatively stable distribution of national comparative advantages over time, there are wide variations in local performance: only a few provinces demonstrate any stability in their specialization over the last decade, with the majority showing decreased specialization. We find a higher average degree of persistence for provinces with districts, but no systematic differences between provinces with or without industrial districts. District provinces show wide variation, with a few concentrating on their past comparative strengths, but many diversifying.
