Staffing pattern (% yes)	Full sample		Innovation sample		Difference?
Staffing pattern (% yes)	% yes	N	% yes	N	Difference?
Rejuvenation—inflow of younger	49.8	9330	56.4	440	p=0.007***
Rejuvenation—outflow of older	50.0	8445	54.6	434	p=0.060**
Loss of firm-specific experience	67.7	9203	68.8	455	p=0.625
High churning level	50.5	11,412	62.3	493	p=0.702

Notes: Pooled results for the years 1998/1999 and 2001/2002. Prevalence of staffing patterns as indicated by values above (= yes) the median of the respective of all establishments operating in the same industry, by dominance and growth regimes. The p-values indicate whether the share of firms experiencing a staffing pattern differs between the full sample (N=15,891) and the innovation sample (N=585).
