Worker Flows and Job Flows in Danish Manufacturing 1980-91

We map turnover of workers and jobs in Danish manufacturing over the 1980 to 1991 period, using information about all individual manufacturing plants. We examine the relation between worker flows and job flows and we study separations from and hires to existing jobs ('replacement hiring') in detail. Our results reveal large heterogeneity among workers as well as plants, even adjusting for the level of job flows. The cyclical properties of worker reallocation point to worker flow dynamics being driven by workers quitting in upturns to find better jobs, rather than by plants upgrading the labour force in recessions
