| In this paper we consider different strategies for implementing a payment for environmental services (PES) program to mitigate deforestation in Mexican common property forests (ejidos). We begin by discussing the policy context within which PES programs find themselves, highlighting other possible interventions to help preserve environmental amenities in Mexico. We then discuss some basic principles of environmental payment schemes, formalizing these into three that we simulate: payment of the opportunity cost for forests at risks; payment for environmental benefits provided by forests at risk; a flat payment scheme with a cap on allowable hectares, similar to the type of program often applied in developing countries; and a program of opportunity cost... |

| In this paper we present a continuous time optimal control analysis of resistance buildup in agricultural chemicals when the supplier is a monopolist. We compare the monopolistic, competitive and socially optimal solutions after establishing the stability of each equilibrium. The central finding is that with a monopolistic supplier, resistance buildup is lower than socially optimal. This directly opposes the standard result in the resistance literature. This implies that policies to manage resistance should vary with the age of the chemical, with no intervention during the lifetime of a patent and an optimal tax once the patent expires. |

| The paper presents a theory of the deforestation of common property forest over space and tests this theory using data from 319 Mexican ejidos. One of the main implications of the model is that at a parcel level, the deforestation decision depends on the qualities of that parcel relative to the others within the community and on aggregate, the decision of how much forest to convert to pasture or agricultural land depends upon the entire distribution of land quality and distance in the ejido. The theory also relates the physical characteristics of the converted land to its marginal value. Aggregate community characteristics affect the demand for forest conversion, in particular, inequality can operate both through individual incentives as well as by... |

| We study the consequences of poverty alleviation programs for environmental degradation. We exploit the community-level eligibility discontinuity for a conditional cash transfer program in Mexico to identify the impacts of income increases on deforestation, and use the program’s initial randomized rollout to explore household responses. We find that additional income increases demand for resource-intensive goods. The corresponding production response and deforestation increase is more detectable in communities with poor road infrastructure. These results are consistent with the idea that better access to markets disperses environmental harm and the full effects of treatment can only be observed where poor infrastructure localizes them. |

| While the demand for traditional agricultural economics is diminishing, there is a growing need for the economics and management of the food sector and the environment. Departments of agricultural economics have shown great flexibility in including agribusiness in their Bachelor's and Master's teaching programs. Ph.D and research programs appear to adjust more slowly to changing demand. Although agricultural economics programs are providing a variety of service course offerings, opportunities for joint programs with biological, physical, and natural sciences, particularly resource management, are not being exploited. If business schools decide to compete for agribusiness students in the future, missed opportunities with other departments and schools may... |
