  1. West Germany, all sectors. 1976–2008, OLS estimations with the coefficient of variation (sd/mean) as a dependent variable in all specifications. Robust standard errors in parentheses. */**/*** indicates statistical significance at the 10/5/1 percent level. Age-cohort cells weighted with number of establishments per cell. Number of establishments per cell vary between 12,979 and 19,972 (mean 15,559) in columns (2) and (4) and between 14,632 and 64,468 (mean 25,661) in columns (1) and (3)
