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...

Proper identification of critical source areas (CSAs) is crucial for improving the efficiency of pollutant reduction and the economic viability of best management practices (BMPs) aimed at controlling non-point source pollution (NPSP). Different identification criteria, referring to different...

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...
