Equilibres multiples avec chômage, coûts de transaction et concurrence monopolistique
AbstractThe properties of WS-PS model are modified when trade activity is explicitly modelled. We introduce transaction costs on the output market to capture multiplicity whatever the degree of returns to scale. The price setting curve can become downward-sloping in the unemployment rate-real wage space. Trading externalities reinforce the effect of strategic complementarities between firms, leading to multiple unemployment equilibria. Moreover, a positive shock on the bargaining power of workers decreases the unemployment rate and the real wage at the low equilibrium, but increases both of them at the high equilibrium.
