Economic integration reduces the costs of factor mobility, producing efficiency gains and contributing to equalization of net factor returns. This raises the cost of income-redistribution policy, thus threatening a basic function of the welfare state. A simple model of costly factor mobility under uncertainty shows that greater factor mobility enables factor owners to pool industry-specific, re...

Randomized response (RR) is a well-known method for measuring sensitive behavior. Yet this method is not often applied because: (i) of its lower efficiency and the resulting need for larger sample sizes which make applications of RR costly; (ii) despite its privacy-protection mechanism the RR design may not be followed by every respondent; and (iii) the incorrect belief that RR yields estimates...
