Biography
Caroline van den Berg is working as a Lead Water Economist in the World Bank’s Global Water Practice, focusing mostly on the economics of water supply, wastewater, sanitation and irrigation water services.  She has extensive experience in the preparation and implementation of investment and development policy operations, and in applied research projects – with a work experience that extends over more than 40 countries in Africa, Asia, Europe, Latin America and the Middle East.   She works on cost-benefit analysis, financial analysis, monitoring and evaluation, benchmarking of utilities, regulation and pricing, energy efficiency in water projects and public finance mostly in relation to the water sector.  She has published regularly in academic journals.  Prior to joining the World Bank, she was a research economist, financial analyst and project economist in the private sector. She earned her M.A. in macroeconomics from the Erasmus University Rotterdam in the Netherlands and a Ph.D. in spatial sciences from the University of Groningen (The Netherlands).

    How "Natural" are Natural Monopolies in the Water Supply and Sewerage Sector? Case Studies from Developing and Transition Economies
    (World Bank, Washington, DC, 2007-02) Nauges, Céline; van den Berg, Caroline
    Using data from the International Benchmarking NETwork database, the authors estimate measures of density and scale economies in the water industry in four countries (Brazil, Colombia, Moldova, and Vietnam) that differ substantially in economic development, piped water and sewerage coverage, and characteristics of the utilities operating in the different countries. They find evidence of economies of scale in Colombia, Moldova, and Vietnam, implying the existence of a natural monopoly. In Brazil the authors cannot reject the 0 hypothesis of constant returns to scale. They also find evidence of economies of customer density in Moldova and Vietnam. The results of this study show that the cost structure of the water and wastewater sector varies significantly between countries and within countries, and over time, which has implications for how to regulate the sector.

    Water Concessions : Who Wins, Who Loses, and What To Do About It
    (World Bank, Washington, DC, 2000-10) van den Berg, Caroline
    This note, based on the World Bank's Private Participation in Infrastructure (PPI) project database, reviews trends in infrastructure projects with private participation in low-income countries. Four main conclusions arise. Surprisingly, the proportion of countries with at least one project - eighty one percent - is higher among low-income, than middle-income countries. As in middle-income countries, most investment has been in telecommunications, or energy projects. However, in low-income countries, well over half the projects are greenfield. And the scale of private participation in low-income countries, lags far behind that in middle-income countries.

    Guidance Note : Public Expenditure Review from the Perspective of the Water and Sanitation Sector
    (World Bank, Washington, DC, 2012-06) Manghee, Seema; van den Berg, Caroline
    The objective of this guidance note: public expenditure review from the perspective of the water supply and sanitation sector is to provide World Bank staff with a body of knowledge and good practice guidelines to help them evaluate the allocation of public resources to water and sanitation services in a consistent manner and to increase their knowledge of public expenditure issues in the sector. This guidance note discusses the challenges that are specific to public expenditure management in water and sanitation and the difficulties often involved in identifying sector expenditures. The challenges particular to this sector stem from three factors. First, countries define water and sanitation differently (e.g., drainage may or may not be included, rural services may be considered separately). Second, responsibilities for water and sanitation policy are often divided horizontally across government ministries and agencies, vertically between national and local governments and functionally among the public, private, and non-governmental sectors. Third, the roles of these multiple actors may be unclear or overlapping.

    Unpackaging Demand for Water Service Quality : Evidence from Conjoint Surveys in Sri Lanka
    (World Bank, Washington, DC, 2006-01) Yang, Jui-Chen; Pattanayak, Subhrendu K.; Jonson, F. Reed; Mansfield, Carol; van den Berg, Caroline; Jones, Kelly
    In the early 2000s, the Government of Sri Lanka considered engaging private sector operators to manage water and sewerage services in two separate service areas: one in the town of Negombo (north of Colombo), and one stretching along the coastal strip (south from Colombo) from the towns of Kalutara to Galle. Since then, the government has abandoned the idea of setting up a public-private partnership in these two areas. This paper is part of a series of investigations to determine how these pilot private sector transactions (forming part of the overall water sector reform strategy) could be designed in such a manner that they would benefit the poor. The authors describe the results of a conjoint survey evaluating the factors that drive customer demand for alternative water supply and sanitation services in Sri Lanka. They show how conjoint surveys can be used to unpackage household demand for attributes of urban services and improve the design of infrastructure policies. They present conjoint surveys as a tool for field experiments and a source of valuable empirical data. In the study of three coastal towns in southwestern Sri Lanka the conjoint survey allows the authors to compare household preferences for four water supply attributes-price, quantity, safety, and reliability. They examine subpopulations of different income levels to determine if demand is heterogeneous. The case study suggests that households care about service quality (not just price). In general, the authors find that households have diverse preferences in terms of quantity, safety, and service options, but not with regard to hours of supply. In particular, they find that the poor have lower ability to trade off income for services, a finding that has significant equity implications in terms of allocating scarce public services and achieving universal water access.
