The paper is part of the interdisciplinary recent concerns of "environmental management", looking to determine the damages caused by pollution, remediation expenditures, and benefits that may arise through the application of remediation techniques and decontamination technologies in the mining...

In this paper, we study the stability of equilibrium for a foreign trade model consisting of three countries. As the gravity equation has been proven an excellent tool of analysis and adequately stable over time and space all over the world, we further enhance the problem to three masses. We use...
