TY - RPRT AU - Polachek, Solomon TI - What Can We Learn About the Decline in U.S. Union Membership from International Data? PY - 2003/Oct/ PB - Institute of Labor Economics (IZA) CY - Bonn T2 - IZA Discussion Paper IS - 896 UR - https://www.iza.org/publications/dp896 AB - This paper is composed of two parts. First, using international data, I corroborate that union density in the U.S. declined because of asymmetric growth between the union and nonunion sectors. I show union density to increase in countries experiencing strong manufacturing growth, and to decline in countries undergoing large women’s increases in nonagricultural employment. Second, I borrow from international relations research on war and peace to develop a cogent reason why union density differs by sector. In this vein, I apply a model primarily used to describe bilateral political interactions to figure out why workers often engage in hostile activities such as strikes. In doing so, I look at the contentious rather than the cooperative “face” of unions. KW - manufacturing growth KW - union density KW - unions KW - international relations ER -
