develop an endogenous growth model to study the long run consequences of offshoring with firm heterogeneity and incomplete contracts. In so doing, we model offshoring as the geographical fragmentation of a firm’s production chain between a home upstream division and a foreign downstream one....

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...

Home country effects of domestic firms investing abroad have been a highly debated issue. Overall, the results of a number of empirical studies seem not to support the fear that MNEs are exporting domestic production and/or jobs; however the issue should be examined more deeply. In particular,...

This paper estimates the diffusion and obsolescence of technological knowledge by technological field, country and type of institutions that generates it. We use two comparable samples of patents and patent citations from the NBER U.S. Patent Citations Dataset (based on patents from the US...

This paper aims at analyzing the characteristics and the determinants of innovation in the mobile communication service industry, by emphasising in particular the role of demand. In a Shumpeterian spirit, we argue that competition in this sector crucially depends upon innovation, and that, given...

Academic inventors are university scientists who appear as designated inventors of patents whose assignee may be either a business company, their own academic institution, or a governmental administration. The paper analyses their relationships entertained with co?inventors, who may be either...

In this paper, we assess the extent of offshoring in the Italian manufacturing industries, and we study how this phenomenon is affecting the skill composition of employment. Measuring offshoring using the import-use matrices of input-output tables, firstly we estimate the impact of offshoring on...

The rise of Fast Ethernet as the dominant standard for high speed connection in the Local Area Network industry is chosen to analyse the relevance of increasing returns and network externalities in determining the speed of standard diffusion. Although it was not the first standard to emerge,...

This paper models the formation of R&D networks in an industry where firms are technologically heterogenous, extending previous work by Goyal and Moraga (2001). While remaining competitors in the market side, firms share their R&D efforts on a pairwise base, to an extent that depends on their...

The geography of innovation traditionally concentrates on localised knowledge spillovers, yet neglects collaboration networks as a means to access knowledge outside the region. Using publication and patent data for 1316 regions in the EU27 plus Norway and Switzerland, we find that both localised...
