Joseph Cook joined the Evans School faculty in 2007.  His research focuses on the intersection of environmental and development economics, particularly around issues of water supply and water resources.  His work is often grounded in non-market valuation and field research, having led ten household surveys in six countries.  

Cook's dissertation work examined the policy and economics of vaccines against cholera and typhoid, two water-borne diseases still prevalent in many countries.  Cook and his co-authors combined household demand data with epidemiological estimates of the cholera vaccine’s “herd immunity” to estimate the optimal Pigouvian subsidy, the first such estimate for vaccines.  More recent work has examined issues of access to water supply in rural Africa.  This includes a three-year panel study in Ethiopia on household time savings from improved water supply and a study in Kenya examining water source choices as well as the coping costs of poor supply.  His expertise also includes water resource economics issues in the United States.  This includes studies on the use of “social norms” in municipal water conservation, and non-monetary preferences of irrigators towards water markets (sales and leases of water rights).  He has a long-standing interest in Washington State water resource issues, and served on a team that was commissioned by the State Legislature to examine the benefits and costs of the multi-billion dollar Integrated Plan for the Yakima River Basin.  Methodologically, his training in non-market valuation, particularly stated preference techniques, has led to several publications on the role of giving respondents overnight to think about a valuation scenario.  Cook and colleagues find that this simple technique, though expensive in the field, lowers average willingness-to-pay by a substantial 30-40%.  

His research has been published in the Journal of the Association of Environmental and Resource Economists,the Journal of Policy Analysis and Management, Environmental and Resource Economics, Economic Inquiry, World Development, Water Resources Research and Environment and Development Economics. 

He is affiliated with the Benefit-Cost Analysis Center at the Evans School and the Center for Studies in Demography and Ecology (CSDE) at UW.  He served as a Resource Person for six years for the capacity-building program at theCenter for Environmental Economics and Policy in Africa (CEEPA), based in Pretoria, South Africa.  He is also a Research Associate with the Kenya center of the Environment for Development initiative.  He has done consulting work for the Asian Development Bank (on Nepal’s Melamchi water supply project), the International Vaccine Institute, the Hopi Tribe, Global Water Challenge, and Orange County (NC).

Cook received a Ph.D. and MS in environmental management and policy from the University of North Carolina, Chapel Hill in 2007. He also received a BS in natural resources from Cornell University in 1996.  In between, Cook worked for an environmental consulting firm and as an RA at Resources for the Future, an environmental economics research institute in Washington, DC.
