Policymakers are concerned about effecting real change with monetary policy, particularly in the context of wage rigidity.

The volatility of stock market returns reacts more to monetary policy announcements when the average time left before the renewal of the employees’ collective agreement is large.

This column examines the link between worker satisfaction and future stock returns in 14 countries. In most but not all countries, employee satisfaction is associated with higher future stock returns. Abnormal returns to companies with high worker satisfaction are significantly increasing in the flexibility of their countries’ labour markets.
