TLDR
In this paper, the potential benefits of reducing human exposure to nitrates in the drinking water supply were evaluated and a survey was conducted with 2.9 million households in four regions studied (White River area of Indiana, Central Nebraska, Lower Susquehanna, and Mid-Columbia Basin in Washington).Abstract:
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 Susquehanna, and Mid-Columbia Basin in Washington). If all households potentially at risk were protected from excessive nitrates in drinking water the estimated benefits would be $350 million.read more

External Costs of Agricultural Production in the United States
Erin M. Tegtmeier,Michael Duffy +1 more
TL;DR: In this article, the authors estimate external costs of agricultural production in the United States in the areas of natural resources, wildlife and ecosystem biodiversity and human health, and they call for a restructuring of agricultural policy that shifts production towards methods that lessen external impacts.

Measuring Consumer Benefits of Food Safety Risk Reductions
TL;DR: This paper explored three valuation techniques that place a monetary value on food safety risk reductions, and presented a case study for each: a contingent valuation survey on pesticide residues, an experimental auction market for a chicken sandwich with reduced risk of Salmonella, and a cost-ofillness analysis for seven foodborne pathogens.

TL;DR: In this paper, the authors quantified the benefits of CRP lands for reducing flood damages, improving water quality and air quality, and contributing to greenhouse gas mitigation in the Indian Creek watershed in Iowa.

Valuation of groundwater quality using a contingent valuation‐damage function approach
TL;DR: Using contingent valuation, the authors estimates a damage function for nitrate (NO3-N) exposures based on actual water test results of individual wells, as measured by willingness to pay for protecting individual well supplies within a 10 mg/L NO3N health standard, are estimated to be a concave function of exposure levels, rising rapidly at low to moderate exposures and then leveling off.

Determining socially optimal rates of nitrogen fertilizer application
TL;DR: In this paper, the authors estimate spatially-explicit socially optimal N fertilizer application rates for corn in Minnesota that account for uncertainty, both in valuation techniques and model parameters, and find that socially optimal rates of nitrogen application are between 0 and 161 kg/ha−1.

Statistical Efficiency of Double-Bounded Dichotomous Choice Contingent Valuation
TL;DR: In this paper, a double-bounded dichotomous choice contingent valuation survey was proposed to improve the statistical efficiency of conventional dichotomy-choice contingent valuation surveys by asking each respondent a second question which depends on the response to the first question.

A satisfactory benefit cost indicator from contingent valuation
John P. Hoehn,Alan Randall +1 more
TL;DR: This article used standard economic concepts to develop a model of individual behavior when subject to the constraints of the contingent valuation choice context, which yields refutable consequences consistent with previously reported empirical findings, including some that have been thought to be anomalous.

The Evolution of a More Rigorous Approach to Benefit Transfer: Benefit Function Transfer
TL;DR: In this article, the authors developed a fairly rigorous approach that involves application of travel cost demand equations and contingent valuation benefit functions from existing sites to the new site to account for the spatial market of a new site (i.e., its differing own price, substitute prices and population distribution).

Optimal Bid Selection for Dichotomous Choice Contingent Valuation Surveys
TL;DR: This paper developed a model for optimal survey design for the dichotomous choice contingent valuation method that finds the bid amounts as well as the sample sizes corresponding to each bid using an iterative procedure to select the survey design that minimizes the mean square error of the welfare measure.
