| Observed and unobserved characteristics of an individual are often used by researchers to explain choices over the provision of environmental goods. One means for identifying what is typically an unobserved characteristic, such as an attitude, is through some data reduction technique, such as factor analysis. However, the resultant variable represents the true attitude with measurement error, and hence, when included into a non-linear choice model, introduces bias in the model. There are well established methods to overcome this issue, which are seldom implemented. In an application to preferences over two water source alternatives for Perth in Western Australia, we use structural equation modeling within a discrete choice model to determine whether... |

| Traditional applications of benefit-cost analysis make use of what we refer to as the "damage function and discounting" (or DFD) approach. This approach is well-suited to the analysis of projects for which the principal benefits and costs occur within the next thirty to forty years, say. However, for projects with significant intergenerational consequences--i.e., impacts that do not arise for hundreds of years or more--the DFD approach becomes almost intractable. We propose an alternative conception of benefit-cost analysis for intergenerational decision-making--the mock referendum--that is: (i) arguably more consistent with the tenets of modern welfare economics; (ii) more amenable to the analysis of long-term projects or policies; and (iii) consistent... |

| This paper analyzes the effect that potential future availability of information has on willingness to pay in a contingent market characterized by uncertainty and irreversibility. In particular, I test whether the effect is consistent with the predictions of Zhao and Kling's (forthcoming) theory of commitment cost. The analysis is performed using the results of a contingent valuation study designed to estimate the degree to which local residents value improved water quality in Clear Lake, a spring-fed, glacial lake located in north-central Iowa. The results show that willingness to pay is highly sensitive to the potential for future learning. Offering survey respondents the opportunity to delay their purchasing decision until more information is available... |

| Estimates of the economic benefits of intervention strategies to make food safer from specific pathogens for different durations of protection are not available. We estimated consumers' willingness to pay for a hypothetical vaccine that would deliver a 1-year, 5- years, 10-years, or lifetime protection against Salmonella, E. coli, or Listeria. We used logit and Tobit models to estimate the economic benefits of food safety measures against these major foodborne pathogens. Based on FoodNet 2002 population survey data, consumers were willing to pay for protection against foodborne pathogens. They were willing to pay more for longer protection and for protection against E. coli compared to Salmonella or Listeria. However, they were less willing to pay if... |

| Frankincense from Boswellia papyrifera forest (BPF) is a traded non timber forest product (NTFP) used in pharmaceutical, food, cosmetic and chemical industries. However, the resource in northeastern Africa is under continuous degradation and requires conservation measures. Data from a discrete choice contingent valuation study are used to assess the factors influencing rural households’ willingness to pay (WTP) and willingness to contribute labor (WTCL) for BPF conservation in Ethiopia. The standard probit, bivariate probit and interval data models were used for modeling respondents’ WTP and WTCL. We found household income as the most important factor affecting WTP whereas number of household labor is the most important factor affecting WTCL. Mean lower... |

| Nitrates in drinking water, which may come from nitrogen fertilizers applied to crops, are a potential health risk. This report evaluates the potential benefits of reducing human exposure to nitrates in the drinking water supply. In a survey, respondents were asked a series of questions about their willingness to pay for a hypothetical water filter, which would reduce their risk of nitrate exposure. If nitrates in the respondent's drinking water were to exceed the EPA minimum safety standard, they would be willing to pay $45 to $60, per household, per month, to reduce nitrates in their drinking water to the minimum safety standard. There are 2.9 million households in the four regions studied (White River area of Indiana, Central Nebraska, Lower... |
