Abstract:
The need for intra-firm incentive schemes allows remodeling the Cournot duopoly in wages (rather than in output levels). In both versions of the Cournot model, a cartel agreement is unstable. The new formulation, however, allows us to demonstrate that a collective wage agreement on minimum wages can stabilize the cartel solution. Beyond its relevance for strategic management, this result has a policy implication: competition authorities should observe collective wage agreements for their potential collusive effect on product markets. Moreover, the model may provide a new explanation why firms in reality pay lower than efficient variable wages and higher fixed wages than predicted by contract theory.
