The economic incentives of work absence are empirically studied using a pan
el of Swedish blue collar workers, both men and women, that either are marr
ied or living with a spouse as married. A model for the daily absence decis
ion is derived from standard economic utility theory. An estimable form for
the annual number of absence days is obtained by considering the data gene
rating process in some detail. The model is estimated, using the first two
moments, with a generalized method of moment estimator. The panel structure
of the data is explicitly considered and a positive dependence between the
number of days absent in the two time periods is found for females. A 1% i
ncrease in the cost will lead to a decrease in the mean number of days abse
nt by 1.8 and 2.7% for females and males, respectively.
