In a survey of UK consumers, we elicited their willingness to accept (WTA) a discount for GM foods and willingness to pay (WTP) a premium for non-GM foods in order to assess their valuation on the non-GM characteristic in food products. Mean WTA is found to exceed mean WTP, suggesting the...

In a survey of UK consumers, we elicited their willingness-to-accept (WTA) a discount for GM foods and willingness-to-pay (WTP) a premium for non-GM foods in order to assess their valuation of the non-GM characteristic in food products. Mean WTA exceeds mean WTP, a finding that suggests the...

This paper reports results from a U.S. national telephone survey on genetically modified foods. The objectives of this paper are to determine the effect of "indifference" response on the estimate of willingness to pay and to test the assumption of common marginal utility of income among respondents.

This study estimates the willingness to pay (WTP) of Loja’s households to protect two micro-basins that supply over 40 percent of potable water to the city. Results indicate that households have an average WTP of $5.80 per month, which corresponds to a 25 percent increase in the self-reported...

Choice of payment vehicle (PV) is important to contingent-valuation practitioners. They are often left using scenarios that may elicit bias responses; for example hypothetical gate fees in open access areas. Utility bills may avoid bias, but introduce a scaling problem. A survey of north-Florida...

This study assesses the economic impact of the Electronic Trade Platform MarketMaker on agricultural producers. Results obtained using contingent valuation techniques indicate that producers are willing to pay $47.02 annually for the services they receive from the platform. Producers’...

This article examines the preferences revealed by three non-hypothetical experiments. We found that WTP estimates from the choice experiment are the highest, followed by that of contingent valuation methods, and then experimental auctions. Our results also suggest that the discrepancies among...

This study evaluated the impact of the South Carolina (SC) agricultural promotion campaign after its first season. Analysis of the survey data revealed that consumer demand for state grown produce has increased by 3.4% which could result in an increase in producer surplus of $2.9 million. Since...

A nationwide survey was conducted to estimate welfare associated with a proposed large-scale wetland restoration project in coastal Louisiana. Both binary- and multinomial-choice survey instruments were administered via Knowledge Networks, with the latter used to estimate willingness to pay for...
