Introducing private sector participation (PSP) into the water and sewerage sectors in developing countries is difficult and controversial. Empirical studies on its effects are scant and generally inconclusive. Case studies tend to find improvements in the sector following privatization, but they...

This paper uses a new dataset, "WATSAN," of private sector participation (PSP) projects for water and sanitation in developing countries to examine the determinants of the number of projects signed for each country between 1990 and 2004. The new dataset improves on existing sources, in...

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...

Physical height is an important economic variable reflecting health and human capital. Puzzlingly, however, differences in average height across developing countries are not well explained by differences in wealth. In particular, children in India are shorter, on average, than children in Africa...

In public-private partnership transactions in the water sector, one of the alleged concerns is that there is little market competition at the auction stage. This paper casts light on a tradeoff between the competition effect at the auction level and potential economies of scale in service...

The authors review the applications of noncooperative bargaining theory to water related issues-which fall in the category of formal models of negotiation. They aim to identify the conditions under which agreements are likely to emerge and their characteristics, to support policymakers in...

Given the relatively small segment of the population that faces genuine affordability problems in Latin America, there appears to be a promising case for using targeted subsidies to reconcile the cost recovery objective with social protection concerns. Social tariff schemes of various kinds are...

The objective of this paper is to explore the impact of Uruguay's privatization and subsequent nationalization of water services on network access and water quality. The results suggest that although the early privatization of water services had little impact on access to the sanitation network,...

Despite efforts to mandate and finance local governments' provision of environmental sanitation services, outcomes remain poor in the villages surveyed in the four South Indian states. The analysis indicates some key issues that appear to hinder improvements in sanitation. Local politicians tend...

Early life health and net nutrition shape childhood and adult cognitive skills and human capital. In poor countries -- and especially in South Asia -- widespread open defecation without making use of a toilet or latrine is an important source of childhood disease. This paper studies the effects...
