This paper examines the tax competition for mobile capital between two symmetric countries in a monopolistic competition economy. Taxation generates its own distortions of location and consumption as long as consumers/governments deviate from the symmetric equilibrium. Taking all possible distortions into account, this paper finds that the equilibrium tax rate may be positive and increasing when trade costs are high while it is negative and decreasing when trade costs are low if consumers have additively separable preferences displaying an increasing relative love for variety. This nonmonotonic relationship of tax rate with trade costs is further accompanied by welfare loss when market integration starts. The procompetitive effect and the income effect are both crucial to deriving the results.
