Previous studies have found that contingent valuation (CV) respondents who are given overnight to reflect on a CV scenario have 30 - 40% lower average willingness-to-pay (WTP) than respondents who are interviewed in a single session. This “time to think” (TTT) effect could explain much of...

We examine risk preferences in an urban setting in a low-income developing country with non- student subjects by adapting the experimental approach of Holt and Laury (2002). We conducted 22 group experiments (n= 404) and used in-kind payoffs. The average midpoint of the CRRA intervals among...

Since 1999 a multilateral effort termed the Nile Basin Initiative has been underway among the Nile riparians to explore opportunities for maximizing the benefits of the river's waters through cooperative development and management of the basin. However, to date there has been virtually no...

Nation-states rarely go to war over water, but it is equally rare that water conflicts in an international river basin are resolved through cooperation among the riparian countries that use the shared resources. Gains from cooperation will mean little to individual riparians unless the required...

This paper reports the main findings from a multi-country research project designed to develop a better understanding of the performance of community-managed rural water supply systems in developing countries. Data was collected from households, village water committees, focus groups of village...

This paper summarizes highlights in the history of the ex-ante economic analysis of large dams. We argue that six key developments are especially important: 1) adding systems analysis; 2) incorporating multiple objectives; 3) introducing environmental and social gains and losses; 4) recognizing...

In Addis Ababa, an increasing block tariff has been used to calculate households' monthly bills for electricity and water services. This study estimates the magnitudes of the combined water and electricity subsidies received by households with private connections to the electricity grid and...

It is often argued that the true benefits of water resource development in international river basins are undermined by a lack of consideration of interdependence in water resource planning. Yet it has not been adequately recognized in the water resources planning literature that overestimation...

This paper summarizes the results of the Ganges Strategic Basin Assessment (SBA), a 3-year, multi-disciplinary effort undertaken by a World Bank team in cooperation with several leading regional research institutions in South Asia. It begins to fill a crucial knowledge gap, providing an initial...
