Tiivistelmä
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 the earlier studies. Using twin differences we find evidence for
positive compensation of adverse working conditions in the labor market.
