The aim of this paper is to highlight empirically some important worldwide differences in the impact of privatization of the fixed-line telecommunications operator on network expansion, tariffs, and efficiency during the 1985-2007 period for a large panel of countries. Our work suggests that the...

This paper has two related objectives. First, it seeks to identify the key determinants of some policies that have been at the heart of the reforms of the telecommunications industry in developing countries, namely, liberalization, privatization, and the (re)structuring of regulation. Second, it...

The main goal of this study is to demonstrate the existence of a significant empirical link between infrastructure and financial sectors reforms the effects of which are reflected in infrastructure sectors performance. This paper reports on the findings of an exploration of this issue for the...

This paper develops a simple model in which a regulated (upstream) transporter provides capacity to a marketer competing in output with an incumbent in the (downstream) gas commodity market. The equilibrium outcome of the firms' interaction in the downstream market is explicitly taken into...

Motivated by recent policy events experienced by the European natural gas industry, this paper develops a simple model for analyzing the interaction between gas release and capacity investment programs as tools to improve the performance of imperfectly competitive markets. We consider a regional...

TThis paper seeks to assess the extent to which a country’s overall level of development and that of its financial sector, in particular, are factors that attract private capital into infrastructure projects. The authors investigate these effects in a 1990–2007 dataset on the power sector in...

This paper explores empirically the link between stocks returns Value-at-Risk (VaR) and the state of financial markets across various holding horizons. The econometric analysis is based on a self-exciting threshold autoregression setup. Using quarterly French and US data from 1970Q4 to 2012Q4,...

This paper develops a theory of sequential investments in cybersecurity in which the software vendor can invest ex ante and ex post. The regulator can use safety standards and liability rules as means of increasing security. A standard is a minimum level of safety, and a liability rule states...

This paper studies a dynamic two-sided market in which consumers face switching costs between competing products. I first show that, in a symmetric equilibrium, switching costs lower the first-period price if network externalities are strong. By contrast, switching costs soften price competition...
