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...

By extending his data, we document the instability of low-frequency regression coefficients that Lucas (1980) used to express the quantity theory of money. We impute the differences in these regression coefficients to differences in monetary policies across periods. A DSGE model estimated over a...

The consumption Euler equation is a building block of modern macro theory. Yet, the existing evidence on aggregate data offers very conflicting results for the estimates of the degree of forward-lookingness and interest rate semi-elasticity. The disappointing performance can be rationalized by...

Almost half of American families did not adjust their consumption following receipt of the 2001 or 2008 tax rebates. Another 20 percent, with low income and more likely to rent, spent a small but significant amount. Households with large spending propensity held high levels of mortgage debt. The...

The announced primary objective of the European Central Bank is price stability. While no restrictive reference is given to how the goal should be reached, such a mandate can be thought as a concern to stabilize some relevant macroeconomic aggregates. Accordingly, we frame ECB monetary policy in...

This paper documents a new stylized fact of the greater macroeconomic stability of the U.S. economy over the last two decades. Using 131 monthly time series, three popular statistical methods and the forecasts of the Federal Reserve’s Greenbook and the Survey of Professional Forecasters, we...

Using a structural VAR with time-varying parameters and stochastic volatility on post-WWII U.S. data, we document a striking negative correlation between the evolution of the long-run coefficient on inflation in the monetary rule and the evolution of the persistence and predictability of...
