Globalization and Factor Income Taxation

Globalization and Factor Income Taxation

 

How has globalization affected the relative taxation of labor and capital, and why? In this paper, Pierre Bachas, Matthew H. Fisher-Post, Anders Jensen, Gabriel Zucman build and analyze a new database of effective macroeconomic tax rates covering 150 countries since 1965, constructed by combining national accounts data with government revenue statistics.

 

4 key findings

  • The effective tax rates on labor and capital converged globally since the 1960s, due to a 10 percentage-point increase in labor taxation and a 5 percentage-point decline in capital taxation.
  • The decline in capital taxation is concentrated in high-income countries. By contrast, capital taxation increased in developing countries since the 1990s, albeit from a low base.
  • The rise in capital taxation in developing countries can be explained by a tax-capacity effect of international trade: Trade openness leads to a concentration of economic activity in formal corporate structures, where capital taxes are easier to impose.
  • International economic integration reduces statutory tax rates, due to increased tax competition. In high-income countries, this negative tax competition effect of trade has dominated, while in developing countries the positive tax-capacity effect of international trade appears to have prevailed.

 

Figure: Effective Taxation of Capital and Labor

The figure below shows the key time series: the evolution of the effective tax rates on labor (red) and capital (blue); and, within capital income, the evolution of the effective tax rate (ETR) on corporate profits (dashed blue). Globally, the ETRs on labor and capital converged between 1965 and 2018. This is due to a large increase in labor taxation and a mild decrease in capital taxation.
