Several recent macroeconomic models assume that real wages are rigid. The wage rigidity of newly hired workers assumes a crucial role in these models, as the decision of whether to open a vacancy is primarily inuenced by real hiring wages. This paper analyses the cyclical behaviour of real wages in Germany. It considers recent concerns that not controlling for cyclical job up-and downgrading leads to biased results. The results indicate that wages are not rigidneither for all workers nor for newly hired workersbut instead respond considerably to business cycle conditions. In the 1930s, Dunlop (1938 and Tarshis (1939) observed the failure of real wages to move countercyclically; the observed correlation between hours and aggregated wages was procyclical but close to zero. However, the early empirical literature on real wage cyclicality did not reach a denite conclusion on whether wages move procyclically or countercyclically. 1 This paper considers recent concerns that not controlling for cyclical job up-and downgrading leads to biased results. The results indicate in Germany neither the wages of all workers nor those of newly hired workers are rigid, but instead respond considerably to business cycle conditions. One potential reason for the inconclusive results in the existing literature is the use of aggregated data. Solon et al. (1994) show that using aggregated time series data instead of longitudinal microdata leads to an underestimation of wage cyclicality due to a composition bias in aggregated statistics. Hence, several papers have used micro-panel datasets to analyse the cyclicality of real wages using the unemployment rate as the business cycle indicator (see, e.g., Solon et al., 1994;Shin, 1994;Devereux and Hart, 2006;Martins, 2007). These studies have provided new insights into the discussion about business cycle uctuations and wage rigidity. All of the studies nd procyclical wage movements; they further show that wage cyclicality diers for dierent categories of workers. Devereux and Hart (2006), for example, show that wages of job stayers are less procyclical than those of within-company job movers and between-company job movers. Recent studies on real wage cyclicality have also been motivated by the so-called Shimer-puzzle (see, e.g., Martins et al., 2012). The canonical Mortensen-Pissarides search-and-matching model (Mortensen and Pissarides, 1994) is unable to explain the cyclical volatility of unemployment (see, e.g., Shimer, 2005). To solve this puzzle, Shimer (2005, p. 45) suggests [a]n alternative wage determination mechanism that generates more rigid wages in new jobs, measured in present value terms [...]. Shimer's suggestion of introducing real wage rigidity into search-and-matching models to generate realistic unemployment volatility has been widely shared (see, e.g., Hall, 2005;Hall and Milgrom, 2008;Kennan, 2010).Nonetheless, the notion of introducing real wage rigidity into (search-and-matching) models has also been challenged (Haefke et al., 2013;Pissarides, 2009).
