Wetlands are among the most important natural resources on earth, as sources of biological, cultural and economic diversity. Conservation and management of wetlands have been identified as priority tasks for action in international conventions and regional policies, but extensive wetland area...

This paper constitutes a component of a larger research project. The larger project attempts to address two issues in international relations - one substantive and theoretical, the second epistemological and ontological. The first issue, which will be the focus of this paper, considers the...

We calculate the equilibrium fraction of cooperators in a population in which payoffs accrue from playing a single-shot prisoner's dilemma game. Individuals who are hardwired as cooperators or defectors are randomly matched into pairs, and cooperators are able to perfectly find out the type of a...

Why do some countries establish their own national eco-labeling programs and some do not? In this paper, we provide both theoretical arguments and empirical evidence suggesting that the answer to this question can shed new light on three questions that have taken center-stage in the trade and...

Failure to accumulate human capital is one of the pressing problems of developing countries. Lacking human capital formation bears consequences on an economy wide level, since education contributes to labor productivity. We examine the impact of increased school enrollment with regard to...

Biofuels production has experienced rapid growth worldwide as one of several strategies to promote green energy economies. Indeed, climate change mitigation and energy security have been frequent rationales behind biofuel policies, but biofuels production could generate negative impacts, such as...

Do transgenic crops cause agrobiodiversity erosion? We hypothesize that they increase productivity and reduce production risk and may therefore reduce farmer demand for on-farm varietal diversity, especially when only a few transgenic varieties are available. We also hypothesize that varietal...

We relate to others in two important ways: we care about others, and we care about how we fare in comparison to others. In some contexts, these two forms of relatedness interact. Caring about others can conveniently be labeled altruism. Caring about how we fare in comparison with others who fare...

We investigate the impact of smallholder vegetable commercialization through the export and domestic market channels on household income and assets in Kenya. We use a survey panel dataset, which allows us to control for unobserved heterogeneity across households, and show that the...
