The negative and stable relationship between an economy’s aggregate demand conditions and overall unemployment is well-documented. We show that there is a large degree of heterogeneity in the cyclical sensitivities of unemployment across worker and economy groups. First, unemployment is more than twice as sensitive to aggregate demand in advanced as in emerging market and developing economies. Second, youth’s unemployment is twice as sensitive as that of adults’. Third, women’s unemployment is significantly less sensitive to demand than men’s in advanced economies. These findings point to the highly unequal impacts of the business cycle across worker and economy groups.

We model worker heterogeneity in the rents from being employed in a Diamond-Mortensen-Pissarides model of matching and unemployment. We show that heterogeneity, reflecting differences in match quality and worker assets, reduces the extent of fluctuations in separations and unemployment. We find that the model faces a trade-off--it cannot produce both realistic dispersion in wage growth across workers and realistic cyclical fluctuations in unemployment.
