A large number of potential determinants of union membership, which often can be interpreted in terms of costs and benefits, have been incorporated into economists' traditional supply and demand framework or into new models of an individual's decision to unionise (such as social custom theory)....

Surveying some recent data and the empirical literature from various disciplines, this paper attempts to shed some light on what we know and don't know about (trends in) unionization and its determinants in advanced countries. It shows that there are relatively few robust stylized facts, for...

Using data from the social survey ALLBUS for West Germany in the period 1980 to 2006, this paper demonstrates that union members are on average older than non-unionized employees. The probability of being unionized shows the inverted U-shaped pattern in age conjectured by Blanchflower (BJIR...

An empirical analysis of various waves of the ALLBUS social survey shows that the level and the structure of unionization has become more and more similar in eastern and western Germany in the period 1992 to 2000. The originally high level of union density in eastern Germany has dropped below...
