The economic consequences of one-third co-determination in German supervisory boards : first evidence for the service sector from a new source of enterprise data

There remains great uncertainty about the economic consequences of co-determination in German supervisory boards. Because employee representation on company boards is mandatory, depending on the legal form and size of the company, a direct comparison of those companies that apply co-determination and those that do not has not yet been possible. However, based on a new kind of combined data set, this paper conducts such a direct comparison, leading to more reliable results about the economic consequences of workers’ participation on two core performance indicators: productivity and profitability. Accordingly, the existence of a co-determined supervisory board seems to positively affect productivity, but not profitability. -- Co-determination ; board-level employee representation ; Germany
