Using data from the IAB Establishment Panel (2004-2013), this paper analyses the incidence, development and interdependence of works councils and other, typically managementinitiated forms of employee participation (such as round tables) in Germany. In the private sector, the incidence of works councils and other forms of participation is similar, but in very few establishments both bodies exist simultaneously. Econometric analyses based on recursive probit models indicate that partly different factors explain the existence of works councils and other forms of participation. Both bodies correlate negatively with respect to their incidence, foundation, and dissolution. This suggests that there exists a predominantly substitutive relationship between works councils and other forms of employee participation.
