Última On the use of honesty priming task to mitigate hypothetical bias in choice AgEcon de Magistris, Tiziana; Gracia, Azucena; Nayga, Rodolfo M., Jr.. We test whether the use of an honesty priming task from the social psychology literature can help mitigate hypothetical bias in stated preference choice experiments (CE). Using a between-sample design, we conducted experiments with five treatments: (1) hypothetical CE without cognitive task, (2) hypothetical CE with cheap talk script, (3) hypothetical CE with neutral priming task, (4) hypothetical CE with honesty priming task, and (5) non-hypothetical CE. Results generally suggest that marginal willingness to pay estimates from treatment 4 where subjects are given honesty priming task before the choice experiment are not statistically different from marginal valuations from treatment 5 where subjects are in a non-hypothetical choice experiment.

Ano: 2012 URL: http://purl.umn.edu/123639 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....

Ano: 2009 URL: http://purl.umn.edu/55867 Comparing choice models of river health improvement for the Goulburn River AgEcon Kragt, Marit Ellen; Bennett, Jeffrey W.; Lloyd, Chris; Dumsday, Robert G.. The extent of the benefits of improved river health remain uncertain. Quantifying these benefits is useful in prioritising policy investments. This study uses the Choice Modelling technique to estimate the value that households attach to attributes of improved river health. Data from a choice modelling survey supported by DSE Victoria are employed to elicit household preferences in a case study of the Goulburn River. Results from conditional and nested logit model specifications indicate that respondents hold positive values for higher levels of fish and bird populations and for increasing riverside vegetation. The standard Hausman test for Independence-from-Irrelevant-Alternatives (IIA) assumptions violations is found to give inconsistent results. The...

Ano: 2007 URL: http://purl.umn.edu/10359 Revisiting Cheap Talk with New Evidence from a Field Experiment AgEcon Silva, Andres; Nayga, Rodolfo M., Jr.; Campbell, Benjamin L.; Park, John L.. We assess the reduction of hypothetical bias in consumers’ willingness to pay (WTP) for products by applying a generic, short, and neutral cheap talk script in a retail setting. Using an open-ended elicitation mechanism with non-hypothetical, hypothetical, and hypothetical with cheap talk treatments, our results indicate that the hypothetical WTP values are higher than the nonhypothetical values, but the hypothetical with cheap talk values are not significantly different from non-hypothetical estimates.

Ano: 2011 URL: http://purl.umn.edu/117168 Willingness to pay for wetland improvement in Vietnam's Mekong River Delta AgEcon Do, Thang Nam; Bennett, Jeffrey W.. A lack of information on economic values, especially non-market values, has contributed to wetland degradation in the Mekong River Delta. To fill this information gap, this study uses choice modelling to estimate biodiversity values of Tram Chim National Park in Vietnam. It is found that Vietnamese respondents are willing to pay for the wetland conservation. However, the willingness to pay estimates differ among sub-populations and are reduced by the use of a cheap talk script. Some issues of applying choice modelling, including questionnaire designs and survey methods are discussed in the context of a developing country.

Ano: 2007 URL: http://purl.umn.edu/10431 Are Consumers in Developing Countries Willing-to-Pay More for Micronutrient-Dense Biofortified Foods? Evidence from a Field Experiment in Uganda AgEcon Chowdhury, Shyamal K.; Meenakshi, J.V.; Tomlins, Keith; Owori, Constance. Vitamin A deficiency is a major health problem in Africa and in many other developing countries. Biofortified staple crops that are high in pro vitamins A and adapted to local growing environment have the potential to reduce the prevalence of vitamin A deficiency. One such example is the orange-fleshed sweetpotato. However because of its distinctive orange color, which is in contrast to the white varieties that are typically consumed in Africa, it is important to assess whether consumers will accept it. It is this question that this paper attempts to address, using a choice experiment with the real product to quantify the magnitude of the premium or discount in consumers’ willingness to pay that may be associated with it. In addition, it also considers...
