We conduct a social dilemma experiment in which real-world leaders can punish group members as a third party. Despite facing an identical environment, leaders are found to take remarkably different punishment approaches. The different leader types revealed experimentally explain the relative...

A popular environmental policy is to pay forest owners for avoiding deforestation on their land. This is an example of "payments for ecosystem services" (PES). This paper shows that liquidity constraints can limit the effectiveness of PES programs. If an individual would have cut down trees to...

Little is known about land cover change in mixed agroforestry systems, which often supply valuable ecological services. We use a spatial regression model to analyze clearing in El Salvador’s shade coffee–growing regions during the 1990s. Our findings buttress previous research suggesting the...

Economic policies that boost profits from agroforesty, thereby creating financial incentives for land managers to favor these systems over less environmentally friendly land uses, could, in theory, have ancillary environmental benefits. This paper analyzes primary and secondary data to determine...

This paper investigates the opportunities for reducing the pressure of urban centers on rural forest areas, using a dataset of 350 urban households in Tigrai in northern Ethiopia. We applied an almost-ideal demand system to fuels. Because the same fuels were not always used by households, the...

Managed forest ecosystems—agroforestry systems in which crops such as coffee and bananas are planted side-by-side with woody perennials—are being touted as a means of safeguarding forests along with the ecological services they provide. Yet we know little about the determinants of land cover...

More than three-quarters of Mexico’s coffee is grown on small plots shaded by the existing forest. Because they preserve forest cover, shade coffee farms provide vital ecological services including harboring biodiversity and preventing soil erosion. Unfortunately, tree cover in Mexico’s...

Households in rural India are highly dependent on firewood as their main source of energy, partly because non-biofuels tend to be expensive. The prevailing view is therefore that, when faced with shortages of firewood in the village commons, such households, and especially the women in them,...
