  • Long-run average welfare in a pollution accumulation model

    This paper studies the pollution accumulation problem so as to maximize the long-run average welfare within a stochastic framework. We consider a sequence of optimal pollution accumulation problems under the discounted criterion. The Hamilton-Jacobi-Bellman (HJB, for short) equation associated with the long-run average problem is obtained as a limit of HJB equations For discounted models. In particular, we solve the problem for first-order disutility functions and present some comparative dynamics results. (C) 2006 Elsevier B.V. All rights reserved.

    This paper considers the problem of pollution accumulation in order to maximize the long-run average welfare functional in environmental economics. We approach the problem by solving the associated Hamilton-Jacobi-Bellman equation in the classical sense, via the viscosity solution method. The optimal policy is shown to exist in a feedback from, and the maximum value is also obtained independently of the initial level of pollution. An equilibrium of the optimal stock of pollution is discussed.

    We study the stochastic optimization problem of renewable resources to maximize the expected discounted utility of exploitation. We develop the viscosity solution method to the associated Hamilton-Jacobi-Bellman equation and further show the C-2-regularity of the viscosity solution under the strict concavity of the utility function. The optimal policy is shown to exist and given in a feedback form or a stochastic version of Hotelling's rule.
