How does globalization affect taxation? The academic wisdom is split on this question. Some argue that globalization spells the beginning of the end of the national tax state, while others maintain that it hardly constrains tax policy choices at all. This paper comes down in the middle. It finds no indication that globalization will fatally undermine the national tax state, but still maintains that national tax policy is affected in a major way. The effect is not so much to force change upon the tax state as to reduce its freedom for change. Comparing the first three decades of the 20th century to the last three decades, it is remarkable how much change and innovation there was then and how much incrementalism and stasis there is today.
