Harberger Model: Effect of Tax Increase<br />

Introduce small tax dτ on rental of capital in sector 2 (K 2 )<br />

All eqns the same as above except r = (1 − dτ)p 2 F 2K<br />

Linearize the 10 eq’ns around initial equilibrium to compute the effect<br />

of dτ on all 10 variables (dw, dr, dL 1 , ...)<br />

Labor income = wL with L fixed, rK = capital income with K fixed<br />

Therefore change in prices dw/dτ and dr/dτ describes how tax is<br />

shifted from capital to labor<br />

Changes in prices dp 1 /dτ, dp 2 /dτ describe how tax is shifted from<br />

sector 2 to sector 1<br />

Kotlikoff and Summers (Section 2.2) state linearized equations as a<br />

fn. of substitution elasticities<br />
