We propose a theory of low-frequency movements in unemployment based on asymmetric real wage rigidities. The theory generates two main predictions: long-run unemployment increases with (i) a fall in long-run productivity growth and (ii) a rise in the variance of productivity growth. Evidence...

In this research, we provide new empirical evidence on the importance of time-varying uncertainty for the exchange rate and the excess return in currency markets. Following an increase in monetary policy uncertainty, the dollar exchange rate appreciates in the medium run, while an increase in...

We propose a theory of low-frequency movements in unemployment based on downward real wage rigidities. The theory generates two main predictions: long-run unemployment increases with (i) a fall in long-run productivity growth and (ii) a rise in the variance of productivity growth. Evidence based...

The paper presents a new empirical regularity between the volatility of productivity growth and long-run unemployment, for a given level of long-run productivity growth. A theoretical framework based on asymmetric real wage rigidities is shown to have the potential to rationalize this finding....
