A number of authors have recently emphasized that the conventional model of unemployment dynamics due to Mortensen and Pissarides has difficulty accounting for the relatively volatile behavior of labor market activity over the business cycle. We address this issue by modifying the MP framework to allow for staggered multiperiod wage contracting. What emerges is a tractable relation for wage dynamics that is a natural generalization of the period-by-period Nash bargaining outcome in the conventional formulation. An interesting side-product is the emergence of spillover effects of average wages on the bargaining process. We then show that a reasonable calibration of the model can account well for the cyclical behavior of wages and labor market activity observed in the data. The spillover effects turn out to be important in this respect. JEL Classification: E32, E50, J64
This study analyses the labour market effects of fixed-term contracts (FTCs) in West Germany by microeconometric methods using individual and establishment level data. In the first part of the study the role of FTCs in firms’ labour demand is analysed. An econometric investigation of the firms’ reasons for using FTCs focussing on the identification of the link between dismissal protection for permanent contract workers and the firms’ use of FTCs is presented. Furthermore, a descriptive analysis of the role of FTCs in worker and job flows at the firm level is provided. The second part of the study evaluates the short-run effects of being employed on an FTC on working conditions and wages using a large cross-sectional dataset of employees. The final part of the study analyses whether taking up an FTC increases the (permanent contract) employment opportunities in the long-run (stepping stone effect) and whether FTCs affect job finding behaviour of unemployed job searchers. Firstly, an econometric unemployment duration analysis distinguishing between both types of contracts as destination states is performed. Secondly, the effects of entering into FTCs from unemployment on future (permanent contract) employment opportunities are evaluated attempting to account for the sequential decision problem of job searchers.
We focus on a quantitative assessment of rigid labor markets in an environment of stable monetary policy. We ask how wages and labor market shocks feed into the inflation process and derive monetary policy implications. Towards that aim, we structurally model matching frictions and rigid wages in line with an optimizing rationale in a New Keynesian closed economy DSGE model. We estimate the model using Bayesian techniques for German data from the late 1970s to present. Given the pre-euro heterogeneity in wage bargaining we take this as the first-best approximation at hand for modelling monetary policy in the presence of labor market frictions in the current European regime. In our framework, we find that labor market structure is of prime importance for the evolution of the business cycle, and for monetary policy in particular. Yet shocks originating in the labor market itself may contain only limited information for the conduct of stabilization policy. JEL Classification: E32, E52, J64, C11
We develop a utility based model of fluctuations, with nominal rigidities, and unemployment. In doing so, we combine two strands of research: the New Keynesian model with its focus on nominal rigidities, and the Diamond-Mortensen-Pissarides model, with its focus on labor market frictions and unemployment. In developing this model, we proceed in two steps. We first leave nominal rigidities aside. We show that, under a standard utility specification, productivity shocks have no effect on unemployment in the constrained efficient allocation. We then focus on the implications of alternative real wage setting mechanisms for fluctuations in unemployment. We then introduce nominal rigidities in the form of staggered price setting by firms. We derive the relation between inflation and unemployment and discuss how it is influenced by the presence of real wage rigidities. We show the nature of the tradeoff between inflation and unemployment stabilization, and we draw the implications for optimal monetary policy. JEL Classification: E32, E50
