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 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...

The paper analyzes the impact of localization, urbanization and competition on firm-level TFP, using a large sample of Italian firm-level data from 1999 to 2007. In particular, the paper explores the nonlinearities of such effects, accounting for the possible presence of critical masses and/or...

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...

This paper investigates the drivers of the environmental innovations (EI) introduced by firms in local production systems (LPS). The role of firm network relationships, agglomeration economies and internationalization strategies is analysed for a sample of 555 firms in the Emilia-Romagna region,...

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...

Following Coe and Helpman (International R&D Spillovers, EER, 39, 859-887, 1995), the literature on the trade-related channels of international knowledge flows has flourished. Departing from Coe and Helpman's tenets on the proportionality of trade and productivity spillovers and thus relaxing...

Recent developments in the new international trade theory stressed the relationship between firm heterogeneity and internationalization performance. The key prediction of these models is that firms with different levels of productivity - the main source of firm heterogeneity - will generally...
