Variable Earnings and Nonlinear Taxation
NBER Working Paper No. 1163 (Also Reprint No. r0965)
We explore the interaction between two facts. The first is that income is variable; the second is that the tax and transfer system transforms before tax income into after tax income in highly non-linear ways. The effect is to penalize (and reward) income variability in a manner which is both substantial and capricious.
