Although open source software has recently attracted a relevant body of economic literature, a formal treatment of the process of com- petition with its proprietary counterpart is still missing. Starting from an epidemic model of innovation di?usion, we try to ?ll this gap. We propose a model...

Although FDI have been at the forefront of economic debate since a long time, economists have not yet developed a unified framework for their investigation. In this paper, we put forward the idea that an essential point to analyze FDI concerns their underpinning motives. Motives are at the core...

The paper analyzes how (production and financial) inter-firm networks can affect firms' default probabilities and observed default rates: an issue the recent crisis has brought to the front of the debate. A simple theoretical model of shock transfer is built up to investigate some stylized facts...

The paper aims at investigating the role that one country's position in the international trade network has in attracting knowledge and technology flows to it. By referring to "indirect" Research and Development (R&D) spillovers, we argue that not only is this position responsible for the number...

In a much cited paper, Wolfgang Keller (Are international R&D spillovers trade-related? Analyzing spillovers among randomly matched trade partners, European Economic Review, 48, 1469-1481, 1998) claims that international R&D spillovers are global and trade-unrelated. In following works, Keller...

The paper analyzes how the structure of interaction networks affects the diffusion patterns and market shares of different products in case of local network externalities and imperfect information. The diffusion of the different products/technologies in the market is modelled as the result of...

The paper investigates the effect of spatial agglomeration on firm exit. In particular, the role of specialization and local variety in production is addressed. The extent to which industrial clusters can be actually retained industrial districts is also considered. Empirical evidence is...

We investigate how the country’s absorptive capacity and relative backwardness affect the impact of international R&D spillovers on domestic Total Factor Productivity (TFP). To account for nonlinearities, we adopt a Panel Smooth Transition Regression (PSTR) approach, where the country’s...

The paper assesses the impact of Organizational Capital (OC) on firm perfor- mance for a sample of European firms. OC is proxied by capitalizing an income statement item (SGA expenses). A rationale for this methodology is provided. Results are robust and show the strong effect of OC on firm...
