“…Unfortunately, there are considerable empirical uncertainties surrounding the reliability and accuracy of CV survey results in developing countries (Whittington, 2002). Furthermore, there are reasons to believe that preference anomalies are likely to be at least as important in developing countries as in developed countries, due to the lack of familiarity with both real and hypothetical 23 Specific examples include the valuation of water quality and sanitation improvements (Whittington al., 1988, 1990, Altaf et al, 1993Singh et al, 1993), biodiversity and recreation (Sattout et al, 2007;Navrud andMungatana, 1994 andMoran, 1994), health (Cahn et al, 2006;Cropper et al 2004 andWhittington et al, 2003) and forestry (;Shyansundar et al 1995;Mekonnen, 2000 andKöhlin, 2000).…”

This study examines the welfare effects of community plantations in Ethiopia via Contingent Valuation. Both single-bounded and double-bounded survey methods were considered, and, with respect to double-bounded methods, the potential for anomalous response behaviour was also taken into account. The results generally confirm that there are statistically significant welfare benefits to be derived from community forestry; however, the range of the estimated benefits is large. After controlling for anomalous response behaviour, the range of estimated benefits narrows, and our preferred estimates place the welfare gain between Ethiopian Birr (ETB) 20.14 and 30.41 per household, which is much lower than the estimated benefits without controlling for anomalous preference responses.

“…These techniques have been widely applied in the environmental field for goods that are not sold in a marketplace (see Hanemann 1994 andCarson 2000 for an introduction to this literature, and Whittington 2002 for applications in developing countries). They have also been used in the health field for goods or services that are not widely available, including vaccines (Canh et al 2006;Cropper et al 2004;Suraratdecha et al 2005;Whittington et al 2002Whittington et al , 2003.…”

We examine the effect of giving respondents time to think about their stated choices (SC) in a survey of cholera and typhoid vaccine preferences in Hue, Vietnam. Because neither vaccine is widely available in Vietnam, we used the SC approach (a stated preference technique) and gave half of our respondents overnight to think about their choices to make the hypothetical valuation scenario as similar to a real-life choice situation as possible. Respondents who were given extra time made fewer choices that violated internal validity tests of utility theory, and had lower average willingness to pay (WTP), confirming a result found in similar studies in the contingent valuation literature.

“…Stated preference studies have been routinely used in environmental economics for nonmarketed goods or services (see Venkatachalam, 2004, for a useful literature review of the method and its strengths and weaknesses) and have more recently been used for vaccines that are either locally unavailable, for example, a cholera vaccine in Kolkata (see Canh et al, 2006;Cook et al, 2007;Lucas et al, 2007;Islam et al, 2008;Kim et al, 2008;Whittington et al, 2008), or have not yet been invented (for example, an HIV/AIDS vaccine- Whittington, Pinheiro, & Cropper, 2003;Cropper et al, 2004;Suraratdecha et al, 2005).…”

Although it is well known that vaccines against many infectious diseases confer positive economic externalities via indirect protection, analysts have typically ignored possible herd protection effects in policy analyses of vaccination programs. Despite a growing literature on the economic theory of vaccine externalities and several innovative mathematical modeling approaches, there have been almost no empirical applications. The first objective of the paper is to develop a transparent, accessible economic framework for assessing the private and social economic benefits of vaccination. We also describe how stated preference studies (for example, contingent valuation and choice modeling) can be useful sources of economic data for this analytic framework. We demonstrate socially optimal policies using a graphical approach, starting with a standard textbook depiction of Pigouvian subsidies applied to herd protection from vaccination programs. We also describe nonstandard depictions that highlight some counterintuitive implications of herd protection that we feel are not commonly understood in the applied policy literature. We illustrate the approach using economic and epidemiological data from two neighborhoods in Kolkata, India. We use recently published epidemiological data on the indirect effects of cholera vaccination in Matlab, Bangladesh (Ali et al., 2005) for fitting a simple mathematical model of how protection changes with vaccine coverage. We use new data on costs and private demand for cholera vaccines in Kolkata, India, and approximate the optimal Pigouvian subsidy. We find that if the optimal subsidy is unknown, selling vaccines at full marginal cost may, under some circumstances, be a preferable second-best option to providing them for free.
