In this note we present an efficient exact algorithm to solve the joint pricing and inventory problem for which Bhattacharjee and Ramesh (2000) proposed two heuristics. Our algorithm appears to be superior also in terms of computation time. Furthermore, we point out several mistakes in the paper...

This study presents a bio-economic model in which the dynamics of a fishery are affected by marine pollution both directly and indirectly. From the optimality analysis it can be seen that as long as a contaminating sector exists near coastal areas the policy on fish resource harvest will be more...
