Unemployment Insurance and Unemployment: Implications of the Reemployment
Bonus Experiments

Abstract
We translate the results of the three reemployment bonus experiments that were
conducted during the 1980s into (a) impacts of a 10-percentage point increase in the
Unemployment Insurance (UI) replacement rate on the expected duration of unemployment;
and (b) impacts of adding 1 week to the potential duration of UI benefits on the expected
duration of unemployment. Our approach is to use an equilibrium search and matching
model, calibrated using data from the bonus experiments and secondary sources. The results
suggest that a 10-percentage point increase in the UI replacement rate increases the expected
duration of unemployment by .3 to 1.1 week (a range consistent with, but only somewhat
narrower than, the existing range of estimates), and that adding 1 week to the potential
duration of UI benefits increases the expected duration of unemployment by .05 to .2 week
(which is toward the low end of existing estimates).
