Unpackaging Demand for Water Service Quality : Evidence from Conjoint Surveys in Sri Lanka

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...

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. 2012-06-22T16:40:22Z 2012-06-22T16:40:22Z 2006-01 http://documents.worldbank.org/curated/en/2006/01/6530297/unpackaging-demand-water-service-quality-evidence-conjoint-surveys-sri-lanka http://hdl.handle.net/10986/8799 English Policy Research Working Paper; No. 3817 CC BY 3.0 IGO http://creativecommons.org/licenses/by/3.0/igo/ World Bank World Bank, Washington, DC Publications & Research :: Policy Research Working Paper Publications & Research
