This paper examines two competing explanations for workers' absenteeism, th
e shirking hypothesis and the adjustment-to-equilibrium hypothesis. Data on
German workers for 1985-88 from the German SocioEconomic Panel al-e used i
n order to estimate the determinants of workers' absenteeism. The results i
ndicate that firm size matters after wage effects are controlled for. This
evidence supports the shirking hypothesis.
