We investigate the behavior of the derivatives of the iterates of Stochastic Gradient Descent (SGD) with respect to that parameter and show that...

Une importante incertitude entoure l'état des menaces sanitaires en temps réel sur les productions végétales. Selon le rapport entre les coûts directs des traitements phytosanitaires et ceux associés aux pertes de rendement, une stratégie de minimisation des risques peut inclure des traitements...

Green insurance can help producers manage the risks of transitioning to more environmentally friendly practices. We investigate the uptake determinant and potential pesticide reduction in the viticulture sector, a major pesticide user, using a choice experiment with 412 French growers. Correcting...
