This study examines differences in employment growth between firms with and without works councils by separating introduction effects from potential selectivity effects. Using a difference‐in‐differences framework, we show that firms with works councils have higher employment growth before adopting a works council. However, employment growth declines after introduction. We identify the reason for lower employment growth in reduced hiring rates, while dismissal rates remain constant.
This study analyzes the relation between works councils and overtime hours in Germany. The estimated effects differ considerably in dependence of standard contracted working time. Furthermore, we find differences across the quantiles of the overtime hours distribution and these differences between quantiles also vary between employees of establishment with and without works councils. By considering contracted working time effects and comparing conditional quantiles we find in some quantiles that employees of establishments with a works council have a higher amount of overtime hours if an employee regularly works 35 hours per week. This effect diminishes with increasing quantiles of the distribution of overtime hours. If an employee of a codetermined establishment regularly works 40 hours per week, overtime hours are reduced. This reduction becomes larger if higher quantiles are analyzed.
Die Konzentration bzw. Streuung der Kapitalanteile variiert in deutschen Aktiengesellschaften erheblich. Die Literatur diskutiert seit langem, inwiefern Unterschiede der Streuung die Effizienz von Firmen beeinflussen. Wir untersuchen die Auswirkung der Streuung von Kapitalanteilen in Unternehmen in Zusammenhang mit Unternehmensmitbestimmung. Auf der Basis von 1583 (1670) Beobachtungen aus 383 (381) Unternehmen wird eine Cobb-Douglas Produktionsfunktion geschätzt, um mögliche Produktivitätsunterschiede zwischen paritätisch mitbestimmten Unternehmen und Unternehmen ohne paritätisch aufgestellten Aufsichtsrat zu identifizieren. Die Existenz eines Großaktionärs hat in kleinen Firmen keine Auswirkung, jedoch reduziert Eigentümerkonzentration eine in unseren Daten vorgefundene negative Wirkung der paritätischen Mitbestimmung. Ebenso ist die Vertretung eines Eigners im Aufsichtsrat dann produktivitätswirksam, wenn das Unternehmen mitbestimmt ist.
