The theory of the dynamics of labor demand is based either on the costs of adjusting the level of employment or on the costs of hiring or firing (of gross changes in employment). We write down a generalized cost of adjustment function that includes both types of cost and allows for asymmetries...

Payroll taxes represent a major distortionary influence of governments on labor markets. Thispaper examines the role of payroll taxation and the social safety net for cyclical fluctuations ina nonmonetary economy with labor market frictions and unemployment insurance, when thelatter is only...

This paper reviews the dramatic and widely noted developments in the German labor market in the past decade and surveys the most plausible reasons for these changes. Alternative hypotheses are compared and contrasted. I argue that the labor market reforms associated with the Agenda 2010 – the...

The supply and demand framework of Katz and Murphy (1992) provides new evidence on the source of changes in socially insured full-time and part-time employment in years preceding and following the implementation of the landmark Hartz reforms in Germany. Our findings are consistent with a stable...

Firing frictions and renegotiation costs affect worker and firm preferences for rigid wages versus individualized Nash bargaining in a standard model of equilibrium unemployment, in which workers vary by observable skill. Rigid wages permit savings on renegotiation costs and prevent workers from...

Standard models of equilibrium unemployment assume exogenous labour market institutions and flexible wage determination. This paper models wage rigidity and collective bargaining endogenously, when workers differ by observable skill and may adopt either individualised or collective wage...
