Do Geographic Concentration and Vertically Related Variety Foster Firm Productivity? Micro‐Evidence from Italy

Abstract: Using a large unbalanced panel dataset of more than 12,000 Italian manufacturing firms for the period 1999-2007, this paper investigates the role of geographic concentration and related variety on firms' total factor productivity (TFP). The main idea is that diversification-captured by a measure of vertically related variety-promotes firm innovativeness and, consequently, productivity, but when the technology has been consolidated, firms join specialized clusters that enhance efficiency. Our results suggest th… Show more

“…A region specializing in a particular composition of complementary sectors will experience higher growth rates than a region specializing in sectors that do not complement each other (Frenken et al, 2007) [36]. According to this view, which is in line with findings provided by Boschma et al (2012), Greunz (2003), Boschma et al (2015), and Cainelli et al (2016), firms and start-ups will or should agglomerate in regions where technological proximity between the firms is high [42][43][44][45]. Frenken et al (2007) studied the role of industrial diversification more closely by analysing whether related or unrelated diversification of industries is rewarding for regional stability and growth [36].…”

“…Hence, a positive coefficient of the cash flow variable means that firms are facing difficulties in raising external capitals, and the higher is the marginal effect of cash flow on investments, the more firms are affected by credit rationing. 2 Localization externalities are captured by an index of geographic concentration of industries measured as follows (CAINELLI et al, 2015):…”

“…However, data on Italian local labour markets are not available for the entire period analysed. Moreover, since provinces have policy powers concerning territorial planning, they may represent an appropriate territorial level to characterize firms' business environment (CAINELLI et al, 2015). 4.…”

“…AIDA, which has recently been used in an increasing number of empirical studies (e.g. Reganati and Sica, ; Colombo and Stanca, ; Ferragina et al ., ; Cainelli et al ., ), collects the annual accounts of Italian enterprises and contains information on a wide set of economic and financial variables, such as sales, costs and number of employees, value‐added, fixed tangible assets, R&D, start‐up year, sector of activity as well as ownership status. In order to study the spillover effects of foreign‐owned enterprises on domestically owned firms, we have identified all Italian firms whose Global Ultimate owner is foreign…”
