Using a representative establishment data set for Germany, we show that, in line with the existing literature for several countries, fi rms' adjustment costs for employment are characterized by a fixed and convex functional form. Furthermore, they are asymmetric with dismissal costs exceeding hiring costs. An analysis of firms' adjustment in the period 1996-2010 also indicates that adjustment behavior has changed over time. Comparing the employment adjustment in the two observed business cycles comprising the years 1996-2003 and 2004-2010, we fi nd that the adjustment speed was higher in the second business cycle indicating that adjustment costs have fallen in recent years.
