In a sharp break with past German research, some recent estimates have suggested that plants with work councils have 25 to 30 per cent higher productivity than their works-councilfree counterparts. Such findings can only serve to buttress the strong theoretical and policy interest in the German...

Using a large panel data set we investigate whether works councils act as sand or grease in the operation of German firms. Stochastic production frontier analysis indicates that establishments with and without a works council do not exhibit significant differences in efficiency.

We estimate the effects of works councils on productivity, 1997-2000, using the IAB Establishment Panel, a nationally representative German data set. We recoup the works council effect by estimating translog production functions, stochastic frontier production functions, and a model in first...
