In many countries, well-meant ad hoc tax incentives proliferate over time, creating an opaque corporate tax structure and many unanticipated tax loopholes. Tax authorities in several countries have considered and sometimes introduced minimum corporate taxes. Liability under such a tax is...

The authors assess the macroeconomic and distributional effects of the privatization that Argentina began in 1989 in gas, electricity, telecommunications, and water and sanitation. Using a computable general equilibrium model, they track the effects of the changes observed between 1993, the...

The link between economic growth, and better provision of infrastructure services may be unproven, but it is clear that reforms to make infrastructure services more competitive (where possible), and to provide strong, and independent economic regulation of natural monopolies, do create an...

The main purpose of this paper is to describe the evolution of the financing structure of regulated privatized utilities and transport companies. To do so, the authors rely on a sample of 121 utilities distributed over 16 countries, and 23 transport infrastructure operators and 23 transport...

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...

This paper presents a basic assessment of the financial performance of infrastructure service operators in developing countries. It relies on a new database of 120 companies put together to track the evolution of the cost of capital, the cost of equity and the return to equity for electricity,...

In reviewing contracts, establishing price limits, or arbitrating conflicts, regulatory agencies and policy advisors face significant information asymmetry in determining the appropriate allowed rate of return, or discount rate. The information gap is especially important in determining 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...

Twenty years ago, as the United Kingdom was getting ready to launch the privatization of its public services, Professor Littlechild developed and operationalized the concept of price caps as a regulatory regime to control for residual monopoly conditions in those services. Ten years later, Latin...

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...
