A Comparison of Approaches to Mitigate Hypothetical Bias AgEcon
Champ, Patricia A.; Moore, Rebecca; Bishop, Richard C..
We compare two approaches to mitigating hypothetical bias. The study design includes three treatments: an actual payment treatment, a contingent valuation (CV) treatment with a follow-up certainty question, and a CV treatment with a cheap talk script. Our results suggest that both the follow-up certainty treatment and the cheap talk treatment produce willingness-to-pay (WTP) estimates consistent with the actual payment treatment. However, the follow-up certainty treatment provides response distributions at all offer amounts that are statistically similar to the actual payment treatment, while the cheap talk treatment provides similar responses only at some offer amounts. Furthermore, the cheap talk treatment is effective only for inexperienced individuals....

Accounting for Respondent Uncertainty to Improve Willingness-to-Pay Estimates AgEcon
Moore, Rebecca; Bishop, Richard C.; Provencher, Bill; Champ, Patricia A..
In this paper we develop an econometric model of willingness to pay that integrates data on respondent uncertainty regarding their own willingness to pay. The integration is utility consistent and does not involve calibrating the contingent responses to actual payment data, and so the approach can “stand alone”. In an application to a valuation study related to whooping crane restoration, we find that this model generates a statistically lower expected WTP than the standard CV model. Moreover, the WTP function estimated with this model is not statistically different from that estimated using actual payment data, suggesting that when properly analyzed using data on respondent uncertainty, contingent valuation decisions can simulate actual payment decisions....

ESTIMATING POST-HARVEST BENEFITS FROM INCREASES IN COMMERCIAL FISH CATCHES WITH IMPLICATIONS FOR REMEDIATION OF IMPINGEMENT AND ENTRAINMENT LOSSES AT POWER PLANTS AgEcon
Bishop, Richard C.; Holt, Matthew T..
A variety of regulations may affect commercial fish catches. We take here as a case in point steps to reduce losses of aquatic organisms due to impingement and entrainment (I&E) at power plants. Methods to evaluate the benefits of such measures are needed for benefit-cost analysis. We use a new approach to estimating ex vessel demand by Holt and Bishop (2002) to address the portion of the benefits that occur post-harvest, that is, down the marketing chain after fishermen sell their catches. The model deals with the dockside prices and quantities for six major commercial species harvested from the U.S. Great Lakes. We use the model to explore the potential magnitude of post-harvest benefits for Great Lakes fisheries. We then turn to a possible approach...

EVIDENCE ON THE ACCURACY OF EXPENDITURES REPORTED IN RECREATIONAL SURVEYS AgEcon
Champ, Patricia A.; Bishop, Richard C..
This article discusses the results of four experiments to test the accuracy of recreational expenditures reported in survey relative to expenditures reported in dairies. We found few situations in which the reported expenditures in the surveys and diaries differ significantly. In general, we conclude that individuals are able to accurately report recreational expenditures in ex post mail surveys. Given the wide usage of survey expenditure data by economists, we find this results encouraging.

Experience, Expectations and Hindsight: Evidence of a Cognitive Wedge in Stated Preference Retrospectives AgEcon
Bennett, Michael; Provencher, Bill; Bishop, Richard C..
This paper combines fishing trip decisions - made before observing trip outcomes - with responses to set of double-bounded dichotomous choice CV questions regarding the outcome of the trip, to explore cognitive elements of choice and their implications for decision modeling and welfare analysis. Extending the approach taken by McConnell et al. (1999), wherein the unobserved component of random utility is linked between the trip decision and the retrospective trip evaluation, we decompose the unobserved component into linked and independent elements, and make the linked component a function of cognitive factors hypothesized as affecting differences between the RP and SP responses. Results suggest that a significant "wedge" exists between the closely related...

HYPOTHETICAL BIAS: THE MITIGATING EFFECTS OF CERTAINTY QUESTIONS AND CHEAP TALK AgEcon
Champ, Patricia A.; Moore, Rebecca; Bishop, Richard C..
This paper reports on an investigation of hypothetical bias and approaches to identifying and mitigating the bias. The split sample design includes an actual donation treatment, a contingent donation treatment with a follow-up certainty question and a contingent donation treatment with cheap talk. Studies comparing contingent values to actual payments consistently find that respondents report higher willingness to pay in a hypothetical payment situation relative to an actual payment situation. While the existence of hypothetical bias has been confirmed in such studies, less attention has been focused on the nature and causes of hypothetical bias. Previous research (Champ et al. 1997, Champ and Bishop 2001) suggests that a small and potentially...

ISSUES IN THE DEVELOPMENT OF AN ESTIMABLE DYNAMIC MODEL OF RECREATION BEHAVIOR AgEcon
Provencher, Bill; Bishop, Richard C..
Static travel cost models have been only partially successful in modeling the sequential aspects of a recreation decision like the decision to fish. In this paper we describe a dynamic structural model of the decision to visit a recreation site. The model is best described as a dynamic multinomial logit model. By virtue of its dynamic nature, the model avoids the problem of the independence of irrelevant alternatives that afflicts static multinomial logit models. Welfare effects of changes in site quality are easily calculated via dynamic programming.

Prior Information, General Information, and Specific Information in the Contingent Valuation of Environmental Risks: The Case of Nitrates in Groundwater AgEcon
Poe, Gregory L.; Bishop, Richard C..
Information, or lack thereof, is an important input in value formation and the distribution of contingent values. Although most conceptualizations of the contingent valuation process stress that information provision should be 'adequate,' very little empirical research has been devoted to assessing the effects of different information flows on contingent values and to establishing a standard of information adequacy for contingent valuation studies. The need for such research is particularly cogent for valuing the benefits of reducing environmental risks, a non-market good which is increasingly being valued with the contingent valuation method. Using nitrates in groundwater as a case study, this paper evaluates and compares health risk perceptions and the...

SENSITIVITY TO SCOPE: EVIDENCE FROM A CVM STUDY OF WETLANDS AgEcon
Mullarkey, Daniel J.; Bishop, Richard C..
Wetlands valuation is a situation in which CVM studies might be expected to fail scope tests. This paper reports results from a split-sample CVM study of Wisconsin wetlands. The survey employed a multiple-bounded, polychotomous-choice format, and compared WTP distributions using the method of convolutions. The survey demonstrated sensitivity to scope.

THE ECONOMIC EFFECTS IN 2002 OF CHRONIC WASTING DISEASE (CWD) IN WISCONSIN AgEcon
Bishop, Richard C..
Wisconsin's 600,000 deer hunters will bear the brunt of the economic losses from chronic wasting disease (CWD) in the Wisconsin deer herd. Though studies have not been done to pinpoint a precise value, preliminary estimates place the losses to deer hunters at between $70 million and $100 million this fall. CWD will also cause deer hunters to spend less on their sport this year than they have in the past. However, the impacts of reduced hunter spending on the Wisconsin economy should not be too large. Losses to the deer hunting economy will be counterbalanced as resident hunters spend their money elsewhere in the economy. Some spending by nonresident hunters will be lost, but deer hunting is a very small part of the tourist economy. Nevertheless, some...

The Economic Effects of Chronic Wasting Disease (CWD) in Wisconsin AgEcon
Bishop, Richard C..
Wisconsin's 600,000 deer hunters will bear the brunt of the economic losses from chronic wasting disease (CWD) in the Wisconsin deer herd. Though studies have not been done to pinpoint these losses, under plausible assumptions, they could have amounted to between $58 million and $83 million in 2002. I would anticipate somewhat smaller losses in 2003, perhaps between $30 million and $53 million. CWD can also be expected to cause deer hunters to spend less on their sport than they have in the past. However, the impacts of reduced hunter spending on the Wisconsin economy should not be too large. Losses to the deer hunting economy will be counterbalanced as resident hunters who reduce expenditures spend their money elsewhere in the economy. Some spending by...

VALIDATING CONTINGENT VALUATION WITH SURVEYS OF EXPERTS AgEcon
Boyle, Kevin J.; Welsh, Michael P.; Bishop, Richard C.; Baumgartner, Robert M..
Contingent-valuation estimates for white-water boating passengers are compared with Likert ratings by river guides. The approach involves asking whether passengers and their guides ordinally rank alternative flows the same. The National Oceanic and Atmospheric Administration's Contingent Valuation Panel (1993) suggested "one might want to compare its (contingent-valuation's) outcome with that provided by a panel of experts." River guides constitute a counterfactual panel of "experts." For commercial trips, optimum flows are 34,000 cfs and 31,000 cfs for passengers and guides, and the comparable figures for private trips are 28,000 cfs and 29,000 cfs. In the NOAA Panel framework, passengers can evaluate the consequences of various river flows and...

Valuing a Spatially Diverse Non-Market Good: The Benefits of Reduced Non-Point Source Pollution in Green Bay, WI AgEcon
Moore, Rebecca; Bishop, Richard C.; Provencher, Bill.
This article presents an empirical approach to correcting for spatial interactions in stated preference data when valuing large-scale, spatially variable environmental improvements. This approach is presented in the context of a contingent valuation study estimating the benefits of reduced non-point source pollution in Green Bay, Wisconsin. The significant spatial variation of water clarity conditions in this large water body was captured using satellite-derived GIS data. This article focuses on two significant challenges: first, ensuring respondents are adequately informed of how the proposed change will impact their individual utility stream; second, dealing with the spatial effects within the estimation model. The GIS water clarity data were used to...

Valuing a Spatially Variable Environmental Resource: Reducing Non-Point Source Pollution in Green Bay, WI AgEcon
Moore, Rebecca; Provencher, Bill; Bishop, Richard C..
This article investigates the value of reducing non-point source pollution in Green Bay, WI. Using stated preference methods, we find the lower bound on the benefits of reducing runoff enough to universally increase water clarity by four feet is greater than $9 million annually. Using a unique survey design, we show that because current water clarity in Green Bay is spatially variable, the value that a household places on this universal improvement depends on the distance of the household’s residence from the Bay and on the particular geospatial location of the residence. This has important implications for estimating aggregate benefits.
