Standard macroeconomic models underpredict the volatility of unemployment fluctuations. A common solution is to assume wages are rigid. We explore whether this explanation is consistent with the data. We show that the wage of newly hired workers, unlike the aggregate wage, is volatile and...

RBC models with search unemployment and wage renegotiation generate too much wage volatility and too stable unemployment rate. Shimer (2004) shows that it is possible to reproduce a volatility of unemployment similar to that observed in actual economies by imposing full real wage rigidity. We...

Although an inverse relationship between sickness absence and unemployment has been documented in a number of studies using either quarterly or annual data from different countries with varying institutional frameworks, it is not yet clear whether this empirical regularity is due to changes in...

This paper investigates whether flexible pay increases the wage costs of job displacement. We use quasi-exogenous variation in the timing of job loss due to mass layoffs spanning over an institutional reform that restricted single-employer bargaining, the Belgian Wage Norm in 1996. We find that...

Do trade unions benefit from economic crises by attracting new members among workers concerned about job security? To address this question, we provide a comprehensive empirical investigation based on panel data from Germany, where workers individually decide on their membership. We analyse...

Wages are only mildly cyclical, implying that shocks to labour demand have a larger short-run impact on unemployment rather than wages, at odds with the quantitative predictions of the canonical search model – even if wages are only occasionally renegotiated. We argue that one source of the...

Recent dynamic contracting models of downward real wage rigidity with "equal treatment" – newly hired workers cannot price themselves into jobs by undercutting incumbents – imply that real wages are relatively rigid in "bad" times but upwardly flexible during "good" times. We use an...
