A linear programming model for air pollution abatement is presented. It is based on the simplifying assumption that air quality goals may be expressed as maximum allowable emission flows in an airshed. The solution of the model for the St. Louis Airshed is examined to evaluate certain charges...

Professor Horowitz correctly identifies the limitation of my assuming separable utility functions to derive a marginal condition for efficiency under uncertainty. Correction this limitation, he provides a simple but powerful condition that encompasses the nonseparable as well as the separable...
