This paper shows that the optimal environmental tax should be less than the marginal environmental damages; since the presence of pre-existing distortionary taxes, increasing the welfare costs is associated with the overall tax code. The reduction of pollution causes the benefits of health by...

Considering Cobb-Douglas function in three variables as an explicit form of production function, in this paper an attempt has been made to maximize an output subject to a budget constraint, using Lagrange multipliers technique, as well as necessary and sufficient conditions for optimal value...
