L'impact macro-économique d'un choc pétrolier


  • Pierre-Yves Hénin


[eng] The macro-economic impact of an oil shock. Pierre-Yves Hénin. The paper provides an analysis of maicroeconomic effets of an oil shock in an economy where prices and wages are sticky in the short run. It relies upon a model which is basically a « disequilibrium » version of .Sachs-Bruno two period model, assuming rationing equilibrium in the first period and walrasian équilibrium in the second one. Both firms and households are intertemporal maximisers, explicit budget constraints are considered and a special attention is paid to the case when a liquidity constraint is imposed to households. For each disiquilibrium regime, the effects of an increase in price of imported oil are shown and the paper give conditions for an oil shock to lead to keynesian unemployment rather than to classical unemployment. It appears that an oil shock is likely to drive in classical. unemployement a net exporting country, an illustration of the so called « Dutch Disease ». [fre] L'article propose une analyse de l'impact macro-économique d'un choc pétrolier dans une économie où les prix et les salaires sont rigides à court terme. Il s'appuie sur un modèle qui peut s'interpréter comme une variante « en déséquilibre » de modèles considérés par M. Bruno et J. Sachs, en supposant un déséquilibre dans la première période et l'équilibre complet à la seconde. A la fois les entreprises et les ménages procèdent à une optimisation intertemporelle, des contraintes de budget explicites sont introduites et l'on envisage en particulier le cas où une contrainte de liquidité est imposée aux ménages. Pour chaque régime d'équilibre avec rationnements, on montre les effets d'un accroissement de prix du pétrole importé et l'article donne les conditions sous lesquelles un choc pétrolier engendrent du chômage keynésien plutôt que du chômage classique. Il apparaît également que le choc pétrolier peut engendrer du chômage classique dans un pays exportateur net, ce qui constitue une illustration du « syndrome hollandais ».
