Thirst For Reform Private Sector Participation In Providing Mexico City S Water Supply

In the early 1990s Mexico City's Federal District (the D.F.) initiated a series of service contracts with four operators in the private sector, each to be implemented in three stages over ten years. The idea was to introduce competitive pressures and to find out if a "gradualist" aaproach would reduce social and political opposition to private sector involvement and would allow the government to address pricing problems and strengthen regulatory arrangements.

August 2001 In the early 1990s Mexico City's Federal District (the D.F.) initiated a series of service contracts with four operators in the private sector--each to be implemented in three stages over ten years. The idea was to introduce competitive pressures and to find out if a "gradualist" approach would reduce social and political opposition to private sector involvement and would allow the government to address pricing problems and strengthen regulatory arrangements. The case in Mexico City offered an opportunity to observe the advantages and disadvantages of gradualist reform. Unfortunately Haggarty, Brook, and Zuluaga find that the long-term nature of an incremental approach does not match well with the generally shorter-term horizons of elected politicians. Difficult decisions in implementation are left to later years, which pushes potentially unpopular actions onto the shoulders of future administrations, while allowing the current government to claim credit for instituting reform. The reform planned--and implemented--was not designed to tackle the city's most serious water problems, including overconsumption and waste. And reform did little to change residential consumers' incentives to conserve water. Overexploitation of the aquifer has been a problem since at least the 1930s. Mexico City is built on a series of drained lakebeds, and the land is soft and prone to settling, or subsiding, as the aquifer is depleted. Several areas of the city center have sunk by over two meters in the past decade alone. And by virtue of its location and elevation, the city's alternative water sources are expensive. The need for change is stark, but the power to undertake reform to tackle broad problems of resource management in the city and surrounding areas lies outside the jurisdiction of the D.F. with the federal government. Such external funding of major supply projects weakens the incentives for conservation. Reform reduced the increasing rate of overexploitation of the aquifer, but partly by simply failing to meet demand. Reform to provide more equitable and sustainable water delivery must focus on improving the efficiency of operations, on substantially reforming the way water resources are priced and allocated, and on the design, management, and pricing of wastewater services. Federal subsidies for new production must be reduced, prices for system operators and consumers must rise, and more must be invested in the treatment and storage of wastewater--all of which requires strong political leadership. This paper--a product of Regulation and Competition Policy, Development Research Group--is part of a larger effort in the group to analyze institutional issues in regulated infrastructure. The study was funded by the Bank's Research Support Budget under the research project "Institutions, Politics, and Contracts: Private Sector Participation in Urban Water Supply" (RPO 681-87).

This comprehensive review of Mexican regulatory policy outlines progress made by Mexico since the 1999 review conducted by the OECD, and makes recommendations for further reforms aimed at promoting investment and boosting productivity and ...

This 2003 edition of OECD's periodic review of Mexico's economy includes special features on structural reform and migration.

Results from a two-step simulation that uses a computable general equilibrium model and detailed consumption and income household data suggests that trade liberalization benefits people in the poorest deciles more than those in the richer ones.

Firms entering and exiting a market contribute almost as much to employment changes as firms continuing in a market. As much effort should be made to understanding sensitivity to wage changes in entering and exiting firms as to understanding wage elasticities in continuing firms.

Electricity, natural gas, telecommunications, railways, and water supply, are often vertically and horizontally integrated state monopolies. This results in weak services, especially in developing and transition economies, and for poor people. Common problems include low productivity, high costs, bad quality, insufficient revenue, and investment shortfalls. Many countries over the past two decades have restructured, privatized and regulated their infrastructure. This report identifies the challenges involved in this massive policy redirection. It also assesses the outcomes of these changes, as well as their distributional consequences for poor households and other disadvantaged groups. It recommends directions for future reforms and research to improve infrastructure performance, identifying pricing policies that strike a balance between economic efficiency and social equity, suggesting rules governing access to bottleneck infrastructure facilities, and proposing ways to increase poor people's access to these crucial services.

The promotion of liberalized and deregulated markets by bilateral and multilateral aid donors, and by global institutions such as the WTO, has led to significant attention being paid to competition and regulatory reforms in developing economies. The process of reform involves the transfer and diffusion of market models derived from practice and theory in developed countries. However, in developing countries, regulation needs to do more than simply promote competitiveness and consumer interests: it also needs to ensure that the market nurtures development. By rigorously examining the numerous impacts of regulation, this book will help to fill a significant gap in the literature on economic and social development. The book, now available in paperback, draws together contributions from leading experts across a range of disciplines including economics, law, politics and governance, public management and business management. The authors begin with an extensive overview of the issues of regulation and competition in developing countries, and carefully illustrate the important themes and concepts involved. Using a variety of country and sector case studies, they move on to focus on the problems of applicability and adaptation that are experienced in the process of transferring best practice policy models from developed to developing countries. The book presents a clear agenda for further empirical research and is notable for its rigorous exploration of the links between theory and practice. Although there is substantial interest in competition and regulation, as yet there has been relatively little investigation of these issues in developing economies. This book redresses the balance and will be a valuable resource for researchers, academics, teachers and students interested in development economics and development studies. It will also be of great relevance for practitioners and policymakers working in the fields of competition policy and regulatory reform.
