Abstract

[fre] Nous introduisons, dans le modèle de contrats échelonnés de Blanchard [1986], une asymétrie entre les durées des contrats et supposons que les contrats de salaire sont (deux fois) plus longs que ceux de prix. Nos résultats mettent en exergue l'importance de la date d'occurrence d'un choc de demande positif non prévu relativement aux dates de révision des prix et des salaires. L'impact initial du choc sur le salaire réel s'avère plus fort quand la date d'occurrence du choc coïncide avec celle de négociation des salaires que lorsque le choc se produit à une date de révision des prix. En effet, les salariés, contraints de négocier pour des périodes plus longues, sont conduits à accroître leurs revendications salaria­les. En revanche, comme les firmes ont la possibilité de réagir plus souvent que les salariés, elles peuvent amortir les effets d'un choc externe. [eng] We suggest in this paper to break off the hypothesis of symmetry between the staggered contracts of prices and wages which characterises Blanchard (1986) model. We introduce an asymmetry between the durations of price and wages contracts considering that wage contracts are twice much longer than the price contracts. Our findings put in quotation an unexpected shock in demand relative to dates of reviewing prices and wages. The initial impulse of real wages proved to be much stronger when the date of such a shock coïncides with wage négocia­tions rather than when the shock occurs at a time of a review date of prices. Since workers are impelled to negociate for longer lengths of time, they are induced to increase their playroll daims. On the other hand, since firms have more often pos­sibility of reacting then workers do, they can, therefore, accomodate the effect of an external shock.
