Abstract:
This paper revisits the relationship between labour taxation and international trade, focusing on the role of domestic labour value added. Using sectoral data from 41 EU and OECD economies over the period 2005-2014, we assess how labour taxes affect exports and imports and how domestic labour value added shapes this relationship. We find that higher labour taxes reduce exports but that the effect depends to a large extent on the share of domestic labour value added, which differs by industries, countries and time periods. Imports do not seem to be affected. This implies that changes in labour taxes will not affect all sectors and countries in the same way and that policy makers should be aware of this when deciding on labour taxes. We also calculate the contribution of labour tax changes to the export dynamics in the analysed period and sample of countries, finding that in general the contribution is small.

Abstract:
This paper investigates how corporate income taxes affect international trade, and identifies the underlying channel. Using data on 33 NACE sectors, for 34 EU and OECD economies, over the period 2005-2014, we find that corporate income taxes reduce exports and imports only when the stock of foreign direct investment (FDI) is high. The effect is present primarily in the service sector and in countries with low corporate taxes. We interpret these findings as evidence that multinational enterprises reduce their operations in countries that raise their corporate taxes. The effect has been found to be small on aggregate, implying that the expected increase in corporate taxes in the future, arising from the global minimum tax, is unlikely to hurt international trade.
