We consider a model of a sector in which the same set of oligopolistic firms faces a common labour supply constraint. The wage is given in the short run, adjusting competitively in the longer run. When the costs of job creation are low relative to the degree of output market power, there exists...

We show that equilibrium involuntary unemployment emerges in a multi–stage game model where all market power resides with firms, on both the labour and the output market. Firms decide wages, employment, output and prices, and under constant returns there exists a continuum of subgame perfect...
