Bilateral internal debt financing and tax planning of multinational firms

This paper examines how taxes affect bilateral internal debt financing among foreign entities of multinational firms. Our data allows us to construct precise bilateral tax-rate differentials between borrowers and lenders of internal debt, which are found to be positively related to internal debt financing of borrowing entities. Compared with previous studies, the estimated tax-elasticity of internal debt exceeds earlier findings by far, most probably accruing to the bilateral specification of tax incentives. Additional investigations on whether and to what extent countries effectively impose anti-tax-avoidance measures show that thin-capitalization rules in host countries are particularly effective.
