This paper estimates the non-linear impact of ICT network on motorway contribution to total factor productivity. Using dynamic panel data of OECD member countries, the paper finds that there exists a critical mass of broadband penetration rate which has the property that if this threshold level...

Theory and evidence on the effects of public investment on growth and productivity are reviewed. It is concluded that, on average, public capital has positive impacts on output and private investment, partly offset by the effects of the taxation needed to finance it. A possible future shortfall...

Most studies of the effects of transport infrastructure on the performance of individual firms have focused on marginal expansions of the rail or highway network over time. In this paper, we study the short-run effects of a large discrete shock in the quality of transport infrastructure, viz....

This study constructs a microdata set of about 143,000 firms to estimate the monetary costs of infrastructure disruptions in 137 low- and middle-income countries, representing 78 percent of the world population and 80 percent of the GDP of low- and -middle-income countries. Specifically, this...

This paper proposes a simultaneous-equation approach to the estimation of the contribution of transport infrastructure accumulation to regional growth. We model explicitly the political-economy process driving infrastructure investments; in doing so, we eliminate a potential source of bias in...
