We consider a labour market model of oligopsonistic wage competition and show that there is a holdup problem although workers do not have any bargaining power. When a firm invests more, it pays a higher wage in order to attract workers from competitors. Because workers participate in the returns...

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...

In a model with imperfect competition and multiple equilibria we show how an increase in the minimum wage can lead firms to reduce wages (and employment). We find some empirical support for this in the Card–Krueger minimum wage data.
