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... |

Non-use values (i.e. economic values assigned by individuals to ecosystem goods and services unrelated to current or future uses) provide one of the most compelling incentives for the preservation of ecosystems and biodiversity. Assessing the non-use values of non-users is relatively straightforward using stated preference methods, but the standard approaches for estimating non-use values of users (stated decomposition) have substantial shortcomings which undermine the robustness of their results. In this paper, we propose a pragmatic interpretation of non-use values to derive estimates that capture their main dimensions, based on the identification of a willingness to pay for ecosystem protection beyond one's expected life. We empirically test our... |

The objective of this study is to analyze consumer behaviour in relation to functional foods by a direct survey. To this end, the proposal is an analysis of the reasons for choosing to consume this type of food or not, accompanied by a supplementary investigation, mostly to assess the relationship between consumption patterns and willingness to pay (WTP) for the most common categories of functional foods, such as milk fortified with CLA (conjugated linoleic acid). Our research shows that a proportion of the population is unaware of the existence of functional foods and their properties. Moreover, it shows that when the concept of functional foods is explained to consumers, this creates a greater willingness to pay for such food, which is strongly linked to... |

We evaluate the impact of different information sequences on participants’ hypothetical willingness to pay (WTP) for food produced using nanotechnology. In three treatment groups, information on the health, societal, or environmental impact linked to nanotechnology was revealed in different sequences: an imposed order, a chosen order, and a chosen order after a discussion among participants. Results show that information choice is important. While in the imposed order, the first information revealed has no effect on WTP, the information chosen first has a strong impact. Discussion has no further impact. Health information was a priority and significantly decreased WTP, while societal and environmental information did not significantly influence WTP. |

Hypothetical bias is a persistent problem in stated preference studies. We propose and test a method for reducing hypothetical bias based on the cognitive dissonance literature in social psychology. A central element of this literature is that people prefer not to take inconsistent stands and will change their attitudes and behavior to make them consistent. We find that participants in a stated preference willingness-to-pay study, when told that a nonhypothetical study of similar goods would follow, state significantly lower willingness to pay than participants not so informed. In other words, participants adjust their stated willingness to pay to avoid cognitive dissonance from taking inconsistent stands on their willingness to pay for the good being... |

The recent food crises in Europe have raised public concerns about the quality and safety of food. The growing concern among the consumers towards food safety issues has increased the demand for quality attributes. Most quality properties of food products can be considered as credence characteristics, quality of which cannot be inferred before the purchase, and sometimes not even after the purchase. The aim of this study is to evaluate, both qualitatively and quantitatively, the value of new information about and the information systems set for credence characteristics of beef. Economics of information is the theoretical framework. The quantitative approach focuses to measure the ex ante value of credence characteristics, and the method of contingent... |

Several times during the last decade consumers have been warned about different incidents concerning food safety, like, salmonella in eggs, cheese and poultry, and pesticides residues in tomatoes. The problem of food safety is still to be a largely latent concern for consumers. The main research goal of this paper is to investigate consumers' risk attitudes and risk perceptions concerning milk safety and to estimate their willingness to pay for extra-safe milk. The data was collected in the Netherlands using a mail survey. 211 usable questionnaires (26%) were returned. Results show that, in general, consumers are not concerned about the safety of milk. However, the results of consumers' perceptions of the "riskiness of milk contamination" for vulnerable... |
