In 2003 we investigated the level of adoption of e-business by manufacturing firms in Europe, identifying four strategies and analyzing them in terms of contingent factors and supply chain integration mechanisms. In this paper we replicate those analyses using the new release of the...

This paper investigates the dynamics of a sample of 131 Science-Based Entrepreneurial Firms (SBEFs), selected out of 500 innovative SMEs that went public in Europe in the period 1995- 2003. We found that the market for the control of these firms was active, with most of our sample firms being...

This paper investigates the efficiency of Italian hospitals during the period 1998–2007 and consider the impact of some DRG distortions like uocoding, cream skimming and readmission. We apply both a stochastic frontier approach and a multilevel model. We show that readmissions are the most...

In this paper we study the efficiency of European airports by applying a DEA model to 57 airports. The sample covers 95% of all the airports with a traffic of at least 5 millions passengers (yearly). We find that largest airports (with more than 10 millions passengers) are more efficient, while...

This paper considers bootstrapping nonstationary panel factor mod- els when possible time dependence is present in the factors dynamics. The analysis does not assume any speci.c DGP, and a sieve bootstrap algorithm is proposed to approximate the autocorrelation structure of the processes...

We develop a dynamic duopoly, where .rms have to take into account a technological externality, that reduces over time their innovation costs, and an inter-.rm spillover, that lowers only the second comer.s R&D cost. This spillover exerts its e¤ect after a disclosure lag. We identify three...

We consider the issue of cross-sectional aggregation in nonstationary and heterogeneous panels where each unit cointegrates. We derive asymptotic properties of the aggregate estimate, and necessary and su¢ cient conditions for cointegration to hold in the aggregate relationship. We then analyze...

In this paper, we study the history of Telecom Italia, the sixth biggest world telecommunication company for turnover, to evaluate how changes in control affected minority protection. Telecom Italia was privatized in 1997 and it has been the target of two takeovers in 1999 by Olivetti and 2001...

Companies obtain significant benefits and resources from university affiliations. Building on recent contributions in the fields of organizational theory and signaling theory, we argue that such relationships redresses investors’ concerns over the legitimacy of firms and acts as an...

This paper focuses on the assumptions of infinite-horizon forecasting in the field of firm valuation. The estimate of long-run continuing values is based on the hypothesis that companies should have reached the steady-state at the end of the period of explicit forecasts, i.e. due to competition...
