“…Although subject to criticisms regarding reliability and validity across the literature, CVM has emerged as a valid tool in estimating the benefits/costs of non-market goods, particularly for direct use values (Arrow et al, 1993;Carson, 2000;Boyle, 2003) which is the case in this instance. If an individual, such as a farmer, has exclusive entitlement or property rights over a good, and is being asked to give up that entitlement in terms of exclusivity of use, then the correct measure within a contingent valuation framework is WTA (Carson et al, 2001).…”

In the European Union, mitigation measures to abate diffuse pollution from agricultural land are implemented under the direction of the EU Nitrates and Water Framework Directives. As these measures are implemented in national policies, a review process will look at the efficacy of the measures with a view to recommending further measures as necessary and following scientific and stakeholder consultation. Riparian buffer zones, beyond those zones used as mandatory set back distances for fertiliser and organic manure spreading, have been used as filters in some countries to attenuate nutrient rich runoff and may be proposed as supplementary measures elsewhere. Notwithstanding the ongoing research on the physio-chemical efficiency of riparian buffer zones, this study examined the willingness of farmers to adopt such features on agricultural land. The sample size was 247 farmers in 12 catchments (approximately 4-12km 2 ) in the Republic of Ireland. The survey was based on a proposal to install a 10 metre deep riparian buffer zone on a five year scheme and the analysis was based on principal components analysis, contingent valuation methodology and a Generalized Tobit Interval model. Results from this analysis indicated that famers' willingness to supply a riparian buffer zone depended on a mix of economic, attitudinal and farm structural factors. A total of 53% of the sample indicated a negative preference for provision. Principle constraints to adoption include interference with production, nuisance effects and loss of production in small field systems. Of those willing to engage with supply, the mean willingness to accept based cost of provision for a 10 metre riparian buffer zone was estimated to be €1513 ha -1 per annum equivalent to €1.51 per linear metre of riparian area.

“…Contingent valuation (CV) is a survey-based methodology for eliciting values people place on goods, services and amenities (Boyle, 2003). This methodology, initially proposed by Ciriacy-Wantrup (1947) and applied first by Davis (1963), asks people to directly value goods for which markets do not exist, and for which, demand is unobservable.…”

“…There can be no anchoring biases using this format. Nevertheless, theoretically, open-ended responses are not considered incentive compatible (Boyle, 2003). Moreover, they suffer from potentially large nonresponse rates, protest answers, zero bids and outliers which may all lead to unreliable responses (Mitchell and Carson, 1989).…”

The value of mortality risk reductions in Delhi, India

Road accidents kill nearly 1.2 million people each year worldwide, two-thirds of whom live in developing countries. Traffic crashes may indeed become the third leading cause of death in developing countries by the year 2020 (Murray and Lopez, 1996). For governments in developing countries to make informed decisions about investments in traffic safety, it is imperative that the benefits of road traffic improvements be monetized and compared with costs. This, however, requires estimates of the value of reductions in risk of death.The goal of the dissertation is to provide estimates of the value of mortality risk reductions in a traffic safety context in Delhi, India. To estimate the value of road safety improvements in Delhi requires understanding the nature of developing country traffic risks. Methods of valuing traffic fatalities used in high-income countries based on seatbelt use or purchase of safer cars are not applicable here.In my survey I asked 1200 commuters what they would pay to reduce their own risk of dying as a (a) pedestrian, (b) driver of a two-wheeler, and (c) commuter, regardless of travel mode. These scenarios mirror the bulk of fatal accidents in Delhi. I find that mean WTP for mortality risk reduction increases with the size of risk reduction, as predicted by economic theory.WTP for a given risk change increases with income and education. The estimation results broadly confirm the Bayesian updating assumption, in that WTP increases with baseline exposure to risk, measured by commute time, whether the respondent travels as part of his job and whether he drives a two-wheeler. Mean WTP is three times larger for a respondent who drives a two-wheeler and travels on the job than for one who does not.The results of my survey indicate that the VSL is individuated, i.e., it varies across groups of potential beneficiaries of traffic safety programs (two-wheeler drivers, persons with bachelors degree, etc.). For the most highly exposed individuals-the VSL is about $150,000 (PPP, 2005

“…Cameron et al (2002) find that OE formats tend to produce more conservative WTP estimates than DC. In this research, I use OE, and apply the Tobit model (Boyle, 2003), which doesn't al-low negative values and accommodates a probability spike at zero ($0). I also use a referendum question and analyze those values using a Logit model (see below).…”

“…Arrow et al (1993) recommend DC, while Boyle (2003) states that OE might have an advantage over other formats as it avoids bid anchoring. DC more closely approximates a market, as consumers are given prices, rather than asked to determine them, and OE questions might be more challenging for some respondents, which could result in non-response or underestimation of WTP (Loomis & White, 1996).…”

Abstract. Traditional gravity fed irrigation systems in Hispano communities in New Mexico, USA, are referred to as acequias. Water scarcity is currently motivating negotiations between acequias and municipalities over sharing agreements. Research on willingness to pay to protect and maintain acequias is still scarce. These valuation data could be helpful to improve the quality of water resources decision making and therefore rural development strategies in this region, which is relatively poor compared to the US average.Data from an open-ended CVM survey are used to examine WTP for a program designed to strengthen and perpetuate irrigation and culture on the acequias of El Río de las Gallinas, in rural northeastern New Mexico. Results indicate that the community supports the program in general, with higher levels of support among rural residents and Anglos.
