Estimating crop rotation effects with farm accountancy panel data

Résumé

Crop rotations effects are key features of environmentally friendly crop production practices but they are poorly documented. The aim of this article is to present an estimation approach of these effects based on farm accountancy data. Estimating crop rotation effects on yield and variable input use levels from farm accountancy data is a challenging issue since farmers’ crop sequence choices are not observed. In response to this data issue, we propose an original approach designed to estimate the crop rotation effects while simultaneously reconstructing farmers’ unobserved crop sequences from farmers’ observed crop production choices. This estimation approach is based on a well-defined statistical background. It relies on simple crop sequence yield and input use models as well as on an assumption stating that farmers are economically rational when deciding their crop sequence acreages. Our approach also makes use of expert knowledge information on crop rotation effects for ‘guiding’ the construction of the crop rotation effect estimators. An illustrative application based on French farm accountancy data demonstrate the empirical tractability of the proposed estimation approach and shows that it yields meaningful estimates of crop rotation effects.
