Using pooled cross-sectional data from 23 OECD countries, between 1965 and
1990, I find evidence that the tax structure affects economic growth. Speci
fically, the proportion of tax revenue raised by taxing personal income has
a negative correlation with economic growth. This result is robust to a ri
gorous sensitivity analysis, where I control for other plausible growth det
erminants in a systematic manner. Also, there is some empirical evidence th
at tax progressivity, measured in terms of the long-run income elasticity o
f tax revenue, is associated with low economic growth.
