Governments should increasingly be able to rely on the private sector for help supporting (and financing) the transport sector - especially infrastructure support services for which there is heavy demand - but first they must improve their regulatory tools and sort out the institutional mess...

The authors review the evidence on the state of infrastructure in the developing world, emphasizing the investment needs and the emerging policy issues. While their assessment is seriously constrained by data gaps, they provide useful insights on the main challenges ahead, emphasizing that, in...

The authors provide empirical evidence on the impact that private participation in infrastructure has had on key macroeconomic variables in a sample of 21 Latin American countries from 1985-98. Specifically, they look at the effects on GDP per capita, current public expenditures, public...

In infrastructure, the possibility of a positive relationship between operators'profitability and the degree of concentration is a major political issue in view of the wide diversity of feelings about the potential role of the private sector. This is particularly important in view of (i) the...

The most effective regulators in developing countriesare following remarkably similar approaches. The main common element across"best practice"countries is the use of relatively simple quantitative models of operators'behavior and constraints to measure the impact of regulatory decisions on some...

The authors analyze the determinants of the efficiency levels reached by twenty one African water utilities. They assess efficiency through the estimation of a production frontier for the sector in Africa. The efficiency estimates confirm much of the common perceptions from partial productivity...
