조세왜곡과 오염배출기업의 최적조세에 관한 고찰

Environmental taxes tend to compound the welfare cost of pre-existing tax distortions, the tax-interaction effect, however they also raise government revenues, tax revenue-recycling effect. By incorporating these two opposite tax effects, this paper examines a second- best environmental taxation for a polluting monopolist with distortionary taxes. The analysis suggests that the complications posed by pre-existing tax distortions as well as market structure can be key considerations in designing environmental taxes. In the tax setting game between regulator and regulated firm, we also derive the equilibrium tax rate and examine its relationship with distortionary taxes.
