Abstract

Each sector of a multi-sector overlapping generations model is an oligempory with a given number of firms, oligopsonists in the sectoral (spatially differentiated) labour market and oligopolists in the sectoral (homogeneous) output market. When there is aggregate unemployment, and a firm raises wages beyond the local full employment level acquiring labour from neighbours, sectoral output supply becomes constant and the firm faces a flat output demand curve under constant returns to labour (upward sloping under decreasing returns). Multiple temporary equilibria and Pareto-ranked steady-state equilibria emerge; the associated sunspot equilibria exhibit counter-cyclical markups, inter alia.
