In most states, unemployment insurance recipients accepting part-time
work can earn up to a specific amount (the ''disregard'') with no redu
ction in benefits. Benefits are then reduced on a dollar for dollar ba
sis for earnings in excess of the disregard. The disregard varies both
across states and within a state over time. This paper analyzes the e
ffects of changes in the disregard on job search behavior. A continuou
s-time job search model is developed and under general conditions an i
ncrease in the disregard is shown to increase both the part-time and o
verall re-employment hazards. Data from the Current Population Survey'
s Displaced Worker Supplements are used to test these predictions. Est
imates from a competing risks model with correlated risks and time-var
ying coefficients shows that increasing the disregard significantly in
creases the conditional probability of part-time re-employment during
the first three months of joblessness.
