The Impact of Fiscal Competition about International Double Taxation in a Nash Equilibrium Point of View

This paper examines international tax rules, with respect to both corporate income tax rates and tax rules for double taxation. This article assumes that governments set non-discriminatory tax rates on domesticand foreign-sourced corporate income and can choose no tax allowance as the tax rule. Consequently, the Nash equilibrium outcomes contradict the intuition underlying previous studies: no tax allowance is chosen as the tax rule where world economic welfare can be maximized. The purpose of this paper is to examine the strategic impact of the tax policies of capital-importing and capitalexporting countries on international investment income.
