Última Valoración económica del rescate del río San Bernardino, Texcoco, Estado de México como belleza natural y recurso hídrico. Colegio de Postgraduados Acuayte Valdés, María del Consuelo. El río San Bernardino presenta un estado completo de contaminación y como consecuencia de la ausencia de agua, el cauce sirve para descargar aguas residuales no tratadas y el depósito de sólidos que se presentan en amontonamiento de basura, llantas, automóviles desvalijados, escombro que como resultado se tiene una pérdida del ecosistema y un foco de infección, siendo esto un problema a la salud de la sociedad. Por tal motivo se realiza una Valorización económica del rescate del río San Bernardino, Texcoco; Estado de México como belleza natural y recurso hídrico, mediante el método de valoración contingente, que estima expresiones de valor por parte de los habitantes entrevistados de las comunidades del río San Bernardino mediante encuestas, el modelo...

Ano: 2011 URL: http://hdl.handle.net/10521/533 Experimental Economics and the Environment: Eliciting Values for Controversial Goods AgEcon Shogren, Jason F.; Parkhurst, Gregory M.; Hudson, Darren. We illustrate the experimental method by examining bidding behavior for controversial goods, i.e., goods in which bidders have positive and negative values. Our results suggest that bidding behavior differs across auction type. Bidders with positive induced values bid sincerely in a WTP auction. Bidders bid conservatively, however, in the WTA auction, foregoing profitable opportunities. Informing bidders of their optimal strategy serves to attenuate bidding discrepancies but does not eliminate them. Treating the WTP and WTA auctions as equivalent given positive and negative values could lead one to overstate the costs relative to the benefits of the controversial good.

Ano: 2010 URL: http://purl.umn.edu/90824 Incentives to Supply Enhanced Ecosystem Services from Cropland AgEcon Jolejole, Christina B.; Swinton, Scott M.; Lupi, Frank. This paper examines the willingness of farmers to participate in hypothetical programs that would pay them to adopt cropping practices that enhance provision of ecosystem services from agriculture. A survey of 3,000 Michigan corn and soybean farmers elicited willingness to adopt four sets of cropping practices that reflected increasing levels of environmental stewardship. Acreage enrollments in the programs were modeled using hurdle models. The acreage that farmers would be willing to enroll depends chiefly on farm size and the perception of environmental improvements from the practices. For farms over 500 acres, the payment offered was also a significant inducement to acreage enrollment in all systems examined. This paper advances the literature on...

Ano: 2009 URL: http://purl.umn.edu/49356 THE WTP/WTA DISPARITY: HAVE WE BEEN OBSERVING DYNAMIC VALUES BUT INTERPRETING THEM AS STATIC? AgEcon Kling, Catherine L.; List, John A.; Zhao, Jinhua. This study advances, and experimentally tests, a new explanation for the disparity between willingness to pay (WTP) and willingness to accept (WTA)-a dynamic neoclassical theory based on the presence of commitment costs. While to date neoclassical models have not explained the observed data patterns well, we find that the commitment cost theory is able to explain adequately the causes and severity of the WTP/WTA value disparity. In particular, using data gathered from an actual marketplace, even the most stringent of our theoretical conjectures-cases where WTP values are predicted to exceed WTA values-oftentimes are met.

The study examines the factors the factors that influence Fort Valley State University students’ willing to purchase transgenic meat. Results show that respondents who said they read labels when shopping were more likely to purchase transgenic meat. Results also suggest that respondents who trust scientists to tell them the truth about transgenic meat were more likely to purchase transgenic meat. Respondents who identified themselves as sophomores, however, were less likely to consume transgenic meat.

Ano: 2010 URL: http://purl.umn.edu/56766 Buying Time: Real and Hypothetical Offers AgEcon Smith, V. Kerry; Mansfield, Carol. This paper provides the results of a field test of contingent valuation estimates within a willingness to accept framework. Using dichotomous choice questions in telephone mail-telephone interviews, we compare responses to real and hypothetical offers to survey respondents for the opportunity to spend time in a second set of interviews on an undisclosed topic. Five hundred and forty people were randomly split between the real and hypothetical treatments. Our findings indicate no significant differences between people's choices with real and hypothetical offers. Choice models indicate the size of the offer and income were significant determinants of respondents' decisions, and these models were not significantly different between real and hypothetical offers.

Ano: 2011 URL: http://purl.umn.edu/103673 The Effect of Uncertainty on Contingent Valuation Estimates: A Comparison AgEcon Shaikh, Sabina L.; Sun, Lili; van Kooten, G. Cornelis. We examine the impact of uncertainty on contingent valuation responses using (1) a survey of Canadian landowners about willingness to accept compensation for converting cropland to forestry and (2) a survey of Swedish residents about willingness to pay for forest conservation. Five approaches from the literature for incorporating respondent uncertainty are used and compared to the traditional RUM model with assumed certainty. The results indicate that incorporating uncertainty has the potential to increase fit, but could introduce additional variance. While some methods for uncertainty are an improvement over traditional approaches, we caution against systematic judgments about the effect of uncertainty on contingent valuation responses.
