Última The adoption of innovative cropping systems under price and production risks: a dynamic model of crop rotation choice 31 Ridier, Aude; Chaib, Karim; Roussy, Caroline. In the paper we investigate the role played by both production and market risks on farmer’s decision to adopt long rotations (over 2 years), considered as innovative cropping systems. We build a multiperiod dynamic farm model (run under GAMS) that arbitrates each year between traditional and innovative rotations. With discrete stochastic programming, the production risk is accounted as an intra-year risk; yearly farming operations are declined according to a decision tree where probabilities are assigned. Subjective yield and cost distributions linked to this decision tree are elicited among a sample of 13 farmers that are experiencing this innovation in South-western France. The price risk is randomly distributed with a given market trend. The crop...

Ano: 2012 URL: http://purl.umn.edu/122440 Linking marketing choices with farming practices of grain producers: A farm level modeling approach applied to the South-west of France 31 Ricome, Aymeric; Kephaliacos, Charilaos; Carpy-Goulard, Francoise; Ridier, Aude; Chaib, Karim. With the increasing commodity prices volatility over the last years and the successive agricultural policy reforms, European grain producers face greater uncertainty. To better understand consequences of a price risk increase on production decisions, marketing decisions and farm revenue as well as linkage between production and marketing decisions, we develop a multiperiodic risk farm model. Production decisions concern selections of crop mix and farming practices (conventional or integrated farming) while marketing decisions focus on four types of pricing arrangements. The model is applied to a representative farmer of a region located in the Southwest of France. The results exposed in this paper shows that with a price risk increase, production...
