This article presents a case study of development of a Payments for Ecosystem Services (PES) program related to drinking water in the city of Copán Ruinas, Honduras. (Text in Spanish)

The methodology used for the design and the implementation of this program is based on an integrated and adaptive management approach. It includes the following elements: general diagnostic, definition of objectives, analysis of enabling conditions, technical design, implementation and evaluation.

Just how important social context is for voluntary contributions is investigated in a natural field experiment, where subjects made either actual or hypothetical contributions to a national park in Costa Rica.

This study found that both anonymity and information about others’ donations influenced contributions, implying that validity testing of stated preference methods needs to include comparisons of hypothetical and actual behavior for given social contexts.

In a natural field experiment, the authors quantified the importance of anonymity, reciprocity, and conformity through the provision of social reference levels in order to explain voluntary contributions. In the study setting, the effects of the various treatments were small, suggesting that the self-image as an honorable person, irrespective of other people’s opinions, could be an important explanation of contribution behavior. The experiment overall showed no clear evidence that current practice by charitable organizations is inefficient.

The purpose of this paper is to test the absolute as well as the relative importance of these three reasons for non-selfish behavior. This is done by conducting a natural field experiment on voluntary contributions to a national park in Costa Rica.

The yellow floating heart is a water weed causing nuisance problems in Swedish watercourses. An economic analysis of this is required where various management options are considered.

In a split sample design, we examine how the number of choice sets, design of the first choice set (starting point), and the choice of attribute levels in the cost attribute affect the precision in the elicited preferences in otherwise completely identical choice experiment surveys.

Using a choice experiment survey, the marginal willingness to pay (WTP) among Swedish households for reductions in power outages is estimated.

We investigate the importance of the social context for people’s voluntary contributions to a national park in Costa Rica, using a natural field experiment.

Although conventional economic theory proposes that only the absolute levels of income and consumption matter for people’s utility, there is much evidence that relative concerns are often important.

This study employed a choice experiment (CE) to ascertain consumer preferences and willingness to pay (WTP) for non-market food product quality attributes. Data were obtained from a large mail survey and estimated with a random parameter logit model.
