Exporting countries are concerned that sanitary standards might shield domestic industry from foreign competition. This study analyzes economic effects of changes in Western Hemisphere sanitary requirements on broiler trade in the Americas. A mathematical programming model detects that if Brazil...

This research investigated the efficiency of the crop enterprise mix farmers formulate to cope with moisture stress risk given the different constraints they are living with. Farmers’ moisture risk coping strategies are mainly explained by the allocation of farm land among the different crop...

We develop a simple model of managing a system subject to pollution damage under risk of an abrupt and random jump in the damage coefficient. The model allows the full dynamic characterization of the optimal emission policies under uncertainty. The results, that imply prudent behavior due to...

We study the optimal control of a pollutant that accumulates with a delay.We find that optimal paths are, in general, non-monotonic and oscillatory, but monotonic if the objective function is additively separable. Hence, using additively separable objective functions as an approximation to a...
