Corporation Tax, the Exchange Rate, and Cross-Border Firm Mobility

In this paper, we extend a new open economy macroeconomics (NOEM) model to examine the effects of a corporate tax reduction on home and foreign countries. The feature of this open economy model is that cross-border relocation of firms is allowed. We show that (i) a reduction in the home corporate tax rate induces an exchange rate appreciation (depreciation) when the degree of cross-border firm mobility is large (small) and (ii) when the degree of cross-border firm mobility is large (small), a reduction in corporate tax is beneficial (detrimental) to the domestic country but detrimental (beneficial) to the foreign country.
