We use data on twins matched to register-based information on earnings to examine the long-standing puzzle of non-existent compensating wage differentials. The use of twin data allows us to remove otherwise unobserved productivity differences that were the prominent reason for estimation bias in...

We use twin data matched to register-based individual information on earnings and employment to examine the effect of height on life-time labor market outcomes. The use of twin data allows us to remove otherwise unobserved ability and other differences. The twin pair difference estimates from...

We perform decompositions and regression analyses that test the routinization hypothesis and implied job polarization at the firm level. Prior studies have focused on the aggregate, industry or local levels. Our results for the abstract and routine occupation groups are consistent with the...
