Technological innovation has always been considered a major stimulus for economic growth. High-speed internet access via broadband infrastructure has undergone rapid development since the end of the 1990s, thanks to the deployment of both fixed and mobile technologies. The present study investigates the impact of fixed broadband diffusion as a technological determinant of economic growth on the basis of a panel of 23 OECD countries over 15 years (1996–2010). The time horizon chosen is suitable for verification of the causal effect on growth of the transition from traditional copper to partially fibre networks. Through implementation of a dynamic panel by using the generalized method of moments (GMM) combined with an instrumental variable (IV) two-stage approach, we found a positive correlation between broadband diffusion and economic growth, even after controlling for countries initial endowment of information and communication technologies (ICT) and for the years of economic crisis. Our main finding provides evidence, through a continuous time interpretation of our estimations, of a quantitatively relevant relationship between broadband diffusion and economic dynamics in the short, medium and long runs. Our findings may be useful to policy makers in that they permit forecasting of the benefits of further transition from broadband to ultra-wide broadband networks.

This paper investigates the evolution of competition policy decisions in the US and, particularly, in the EU, concerning mandatory access to an essential facility held by a dominant firm. Based on some recent and controversial EU antitrust decisions, we outline a comprehensive test for identifying an essential facility and consequently imposing a mandatory access obligation on dominant firms. © 2007 by bepress

The presence of exogenous global shocks due to the 2007/2008 economic and financial crisis and the current global pandemic crisis are deeply hampering economic operators' overall ability to access credit. Small and medium‐sized enterprises and start‐ups are most severely affected by credit rationing. This paper investigates whether access to bank loans in the early stage of a start‐up's lifecycle is a predictor of a firm's default in a time of economic crisis. We ground our analysis on a firm‐level longitudinal data set of Italian new capital companies born from 2004 to 2006. Implementing a discrete‐time proportional hazard model we study their likelihood of default up to 2014 after controlling for a consistent number of other firms, industry and innovation related characteristics. The main findings confirm that access to bank loans significantly enhances the resilience of Italian start‐ups. By taking into consideration the sectoral degree of innovation where firms operate, we also find that bank financing still exerts a positive influence on firm survival in both less and more innovative industries. However, there is evidence of a stronger positive influence on of long‐term debt on the survival of firms operating in low‐ and medium‐low innovative industries.
