In this paper, we investigate how different levels of entrance fees affect donations for a public good, a natural park. To explore this issue, we conducted a stated preference study focusing on visitors’ preferences for donating money to raise funds for a protected area in Costa Rica given...

Using a natural field experiment in a recreational site, a public good almost fully dependent on voluntary donations, we explored the crowding-out effect of gift rewards. First, we investigated whether receiving a map in appreciation of a donation crowded out prosocial behavior and found no...

This paper presents an institutional analysis of the underlying factors affecting the performance of drinking-water community organizations in rural areas of Costa Rica. These organizations provide water to more than 60 percent of the total rural population. There is, however, a great disparity...

Tourism associated with beaches, protected areas, and other natural resources often has serious environmental impacts. The problem is especially acute in developing countries, where nature-based tourism is increasingly important and environmental regulation is typically weak. Eco-certification...

The risk of losing income and productive means due to adverse weather can differ significantly among farmers sharing a productive landscape and is, of course, hard to estimate or even “guesstimate” empirically. Moreover, the costs associated with investments in adaptation to climate are...

Choice experiments, a stated preference valuation method, are proposed as a tool to assign monetary values to environmental externalities during the ex-ante stages of environmental impact assessment. This case study looks at the impacts of the Costa Rican Institute of Electricity’s Toro 3...

We conducted a field experiment in a protected area to explore the effects of conformity to a social reference versus a comparable, but imposed, suggested donation. As observed before, we see visitors conforming to the changing social reference. On the other hand, the treatment in which we...

We looked at risk and ambiguity attitudes among Ethiopian peasants in one of the poorest regions of the world and compared their attitudes to a standard Western university student sample elicited by the same decision task. Strong risk aversion and ambiguity aversion were found with the Ethiopian...

We investigated attitudes toward positionality among rural farmers in northern Ethiopia, using a tailored two-part survey experiment. On average, we found positional concerns neither in income per se, nor in income from aid projects among the farmers. These results support the claim that...
