Abstract: | Using a finite-horizon general equilibrium model with uncertainty and money, we characterize situations where tax arbitrage opportunities may arise for international portfolio investors in an economy with heterogeneous capital income taxation when there is some scope to evade taxes on foreign capital income. We derive tax-modified uncovered interest parity conditions and forward rates similar to the no-tax ones, but augmented by tax-induced “risk-premium” terms; covered interest parity conditions remain unaffected by the introduction of capital income taxes, a consequence of our approach of bounding tax-based arbitrage without restricting arbitrage per se. |
