[fre] Une estimation d'équations d'emploi et de salaire au niveau sectoriel sur données trimestrielles par Jean-Pierre Laffargue et Yannick L'Horty- Cet article estime deux équations de demande de travail et de fixation du coût du travail sur données trimestrielles françaises pour les différents secteurs marchands. Ces équations reposent sur un modèle théorique de concurrence monopolistique entre firmes et de négociation salariale entre entreprises et syndicats. Les méthodes d'estimation prennent en compte les développements récents de la théorie de la cointégration en univariée, et incluent de nombreux tests de spécification et de stabilité des coefficients. L'emploi apparaît fortement rigide et présente une élasticité négative par rapport au coût du travail. Celui-ci est assez flexible et augmente avec le taux de remplacement et le coin salarial, mais diminue avec la progressivité de celui-ci. Les effets du progrès technique et de la durée du travail sur ces deux variables sont aussi étudiés. [eng] An Estimation of Employment and Wage Equations at Sector Level Using Quarterly Data by Jean-Pierre Laffargue and Yannick L'Horty This article estimates two labour demand and labour cost setting equations using French quarterly data for the different market sectors. These equations are based on a theoretical model of monopolistic competition among firms and wage bargaining between firms and unions. The estimating methods make allowance for recent developments in univariate cointegration theory and include a number of specification and coefficient stability tests. Employment appears to be extremely rigid and its labour cost elasticity is negative. The cost of labour is fairly flexible and increases with the replacement rate and the wage wedge, but decreases with the progressive increase in the wage wedge. The effects of technological change and the length of the working week on these two variables are also studied.
