Quantitative models for climate policy modeling differ in the production structure used and in the sizes of the elasticities of substitution. The empirical foundation for both is generally lacking. This paper estimates the parameters of two-level CES production functions with capital, labour and...

Shade-grown coffee provides a livelihood to many farmers, protects biodiversity, and creates environmental services. Many shade-coffee farmers have abandoned production in recent years, however, in response to declines in international coffee prices. This paper builds a farmer decision model...

International Financial Institutions have advocated the privatization of integrated agricultural monopsonies in developing countries with the hope that competition between private firms under a contract farming system would reduce inefficiencies in production and enable farmers to obtain a...

Rapid industrial development and urbanization transfer more and more land away from agricultural production and affect the patterns of land use intensity. This paper analyzes the determinants of land use by modeling arable land and sown area separately. An inverse U-shaped relationship between...

Formulation of strategies for sustainable development should consider environmental effects of economic activities and the feedback from quality of environmentla resources on economic productivity. This paper develops a framework incorporating these interdependencies between economic and...

La problematique d'un developpement soutenable (ou developpement durable) n'est generalement abordee que dans une perspective globale, celle de la prise en compte et de la maitrise des risques ecologiques a l'echelle de la planete, risques engendres par le modele de developpement privilegie dans...
