We look at the effect of tax progression in imperfect labour markets. The models considered are union models, an equilibrium search model with wage bargaining, an equilibrium search model with wage posting by firms and efficiency wage models. We find that in all basic models, an increase in tax...

We analyze to what extent skill heterogeneity in the labor market with different wage formation mechanisms can explain the features of the Spanish labor market. The model assumes two types of workers with differences in skills. Skilled labor sets wages in an efficiency way while unskilled labor...

We consider a dual labor market with a continuum of heterogeneous workers differentiated by their ability of acquiring a specific training. In the primary sector, jobs require specific training and firms set efficiency wages. In the secondary sector, wages are competitive and no training is...

This paper is a first attempt to analyse the consequences of establishing the internal market when taking account of labour market effects of product market integration. Our main focus is on market power, and we show that both labour unions and firms may lose market power when product markets...

Cet article propose un processus de détermination explicite des allocations de chômage dans un modèle dynamique de négociations salariales. Nous supposons que celles-ci sont déterminées au niveau centralisé en prenant en compte leur impact sur les salaires et sur le taux de chômage. Nous...

Cet article analyse les implications de la réallocation géographique de la main-d’oeuvre sur la dynamique du chômage. On considère un modèle à deux régions où un processus d’appariement rend explicite la dynamique des flux sur le marché du travail. L’influence des déplacements de...

We show that accommodation policies may render efficient bargaining in the labour market unsustainable as a perfect Nash equilibrium of the infinitely repeated game. In fact, in the eyes of the labour market participants, efficient bargaining may be Pareto-dominated by the monopoly-union...

We investigate how continental European unemployment can be reduced without reducing unemployment benefits and without reducing the net income of low-wage earners. Lower unemployment replacement rates reduce unemployment, the net wage and unemployment benefits. A lower tax on labour increases...

The label “Keynes-Negishi equiibria” is attached here to equilibria in a monetary economy with imperfectly competitive product and labor markets where business firms and labor unions hold demand perceptions with kinks - as posited in Negishi’s 1979 book Microeconomic Foundations of...

This paper analyses how a diversifying firm can strategically design its wage policy in order to gain market power in unionized markets. This paper shows that union power in the local market power in the local market coupled with the nature of the wage contractual agreement process-i.e. the type...
