The authors construct a regulation model in which renegotiation occurs due to the imperfect enforcement of concession contracts. This enables the authors to provide theoretical predictions for the impact on the probability of renegotiation of a concession, regulatory institutions, institutional...

This paper investigates the effects of political (mis)alignment on public service delivery when mandates are shared between state and local governments. We analyze sewage treatment policies in the state of São Paulo, Brazil. Relying on difference-in-differences estimations, we establish a...

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...

Almost a decade after Argentina began privatizing its railways, resolution of conflicts between regulators, users, and operators continues to take longer, and to be more difficult, than expected. The authors contend that many of these conflicts arose because there are no rules for interactions...

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...

Economists often characterize the regulation of monopolies as a"game"(between the regulator and the service provider) in which the two players do not share the same information. The regulator is assumed to have poorer information than the service provider about the scope of future efficiency...

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...

It is commonly argued that when the benefits of an infrastructure service are mostly local and there is little scope for economies of scale - as in urban transit, road maintenance, water supply, and solid waste management - decentralization is the most effective way to deliver service. Those...
