Industrial classifications offer arguably poor schemes for classifying innovative activity. Moreover, a single measure incorporating technological relatedness between the inherent classes, captures the neglected issue of Jacobs (1969) and Marshall (1920), that the degree of relatedness of...

In this paper we exploit new data on US inventors in Organic Chemistry, Pharmaceuticals, and Biotechnology to revisit the JTH test of the localization of knowledge spillovers (Jaffe, Trajtenberg, and Henderson; 1993). We find that inventors who patent across different companies contribute...

We analyse inter-regional research collaboration as measured by scientific publications and patents with multiple addresses, covering 1316 NUTS3 regions in 29 European countries. The estimates of gravity equations show the effects of geographical and institutional distance on research...

This paper examines whether location in strong industrial clusters translates into a higher probability of innovating. A firm-level analysis of the UK and Italy is performed. Innovative activities of firms (European patent data for 1988-98) are related to regional employment, other...

This paper investigates e-commerce strategies when in addition to the price, firms can control the size of the market area. Due to the shape of the commercial costs (e.g. costs of the e-commerce activity) the following results emerge: 1) if the average costs of commercial are decreasing in the...

The standard two-country model of international trade with monopolistic competition predicts a more-than-proportional relationship between a country’s share of world production of a good and its share of world demand for that same good, a result known as the ‘home market effect’. We first...

University-industry knowledge transfer is nowadays a very fashionable research subject, both in economics, and in management and policy studies. "Distance" between the two realms of academic and industrial research has been increasingly called in to explain the extent at which the academic...

A well-grounded empirical and theoretical literature shows that local production systems can benefit from external economies generated by a shared ‘industrial atmosphere’. Many scholars would agree that in contexts as industrial districts, clusters and local systems, economic actions are...

The paper investigates the diversified patterns of outsourcing in the Lombardy region and relates them to the probability of introducing product and process innovation. Based on a large firm-level survey, we show that outsourcing processes are strongly regionally embedded and that offshoring is...

Several scholars have tried to focus on growth accounting of specific examples of General Purpose Technologies (GPTs). But, what are the factors that might make a General Purpose Technology succeed or fail once the invention has been "triggered"? This paper is a preliminary answer to this...
