Abstract
This paper takes a fresh look at the often confused – and therefore confusing – debate on the role of wage policy in tackling Germany’s unemployment problem. The key issues in this debate are the relative importance of wages and aggregate demand in the determination of employment, the appropriate behavior of wages in relation to productivity growth, and the significance of the purchasing power effect of wages. We argue that the most useful tool to address and resolve these issues is the basic textbook model of aggregate supply and aggregate demand. Most importantly, the model predicts that employment is governed by the ratio of aggregate nominal demand and the nominal wage level. The empirical picture strongly supports this assertion. In contrast, the relation between the rate of wage growth and the rate of productivity growth does not play the causal role in determining employment that is widely attributed to it.
