This article aims to show that if the farm sample under consideration is characterized by significant heterogeneity, recovering output-specific input uses or modeling farm-level input uses may be more complicated than previously recognized. The article theoretically investigates the problems...

The allocation of variable inputs among crops is a common problem in applied studies that use farm accountancy data. Standard farm accounting information is typically restricted to aggregate or whole-farm input expenditures; there are usually no details on how these expenditures are split among...

This paper proposes an analytical framework allowing estimation of the effects of the new instrumentation of the CAP in the arable crop sector--price cuts, compensatory payments and land set-aside schemes--on crop acreage allocations, supplies and yields. Duality theory is used to model crop...

This paper proposes an ex ante evaluation of the willingness to adopt agro-ecological innovations aimed at reducing pesticide use for banana production in the French West Indies. Four innovative systems, including intercropping, improved fallow and new pest-tolerant varieties, are proposed to a...
