We show that this empirical observation is consistent with the strategic effects of such restrictions in a welfare state in the context of optimal direct taxation in the tradition of Mirrlees (1971). Our results also apply to non-welfarist states which have income redistribution, but not in purely extortionary states. %K labor unions %K work hours %K optimal income taxation
