TY - RPRT AU - Wagner, Joachim TI - One-third Codetermination at Company Supervisory Boards and Firm Performance in German Manufacturing Industries: First Direct Evidence from a New Type of Enterprise Data PY - 2009/Aug/ PB - Institute of Labor Economics (IZA) CY - Bonn T2 - IZA Discussion Paper IS - 4352 UR - https://www.iza.org/publications/dp4352 AB - This paper contributes to the empirical literature on the co-determination – firm performance nexus by using a new type of data that combines information on the co-determination status of enterprises from a commercial data base and supplementary information collected from the firms with comprehensive data on the firms from official statistics. The data allow for the first time a direct comparison of enterprises from the same size class with and without codetermination at the supervisory board level. It is shown that one-third codetermination at the supervisory board level in limited-liability companies from West German manufacturing industries seems to be neither positively nor negatively related to two core firm performance indicators, productivity and profitability.
