Therefore this paper estimates an empirical model for union membership and attempts to decompose the difference in the percentage of union members among employees over time (and between western and eastern Germany) into the share that is due to differences in characteristics and attitudes of the workers and the residual share that reflects the different coefficients linking these characteristics and attitudes to the probability of being a union member as well as unobserved and unmeasurable factors.
