Política Ambiental: A Utilização de Taxas Pigouvianas no Caso Dinâmico

Abstract

The adoption of instruments of environmental policy (to correct the problems posed by pollution) is approached generally in a static context. The objective is normally to find out the optimal level of a control variable. If this variable is represented by taxes, firms face additional costs, and can be forced to go out from the market. However, given that relative prices of inputs change, it is expected that occurs a process of substitution. In this paper, the objective is the determination of a dynamic process that, through a succession of feasible states to the economy, can bring it from an inefficient situation to an optimum state. To do this, Pigovian taxes are used.
