Endogenous Labor Supply in an Estimated New-Keynesian Model: Nominal versus Real Rigidities
The deep deterioration in the labor market during the Great Recession, the subsequent slow recovery, and the missing disinflation are hard to reconcile for standard macroeconomic models. We develop and estimate a New-Keynesian model with financial frictions, search and matching frictions in the labor market, and endogenous intensive and extensive labor supply decisions. We conclude that the estimated combination of the low degree of nominal wage rigidities and high degree of real wage rigidities, together with the small role of pre-match costs relative to post-match costs, are key in ...

Why Didn’t Inflation Collapse in the Great Recession?
GDP contracted 4 percent from 2008:Q2 to 2009:Q2, and the unemployment rate peaked at 10 percent in October 2010. Traditional backward-looking Phillips curve models of inflation, which relate inflation to measures of “slack” in activity and past measures of inflation, would have predicted a substantial drop in inflation. However, core inflation declined by only one percentage point, from 2.2 percent in 2007 to 1.2 percent in 2009, giving rise to the “missing deflation” puzzle. Based on this evidence, some authors have argued that slack must have been smaller than suggested by ...

Oil Prices, Gasoline Prices and Inflation Expectations: A New Model and New Facts
The conventional wisdom that inflation expectations respond to the level of the price of oil (or the price of gasoline) is based on testing the null hypothesis of a zero slope coefficient in a static single-equation regression model fit to aggregate data. Given that the regressor in this model is not stationary, the null distribution of the t-test statistic is nonstandard, invalidating the use of the normal approximation. Once the critical values are adjusted, these regressions provide no support for the conventional wisdom. Using a new structural vector regression model, however, we ...

Inflation in the Great Recession and New Keynesian models
It has been argued that existing DSGE models cannot properly account for the evolution of key macroeconomic variables during and following the recent great recession. We challenge this argument by showing that a standard DSGE model with financial frictions available prior to the recent crisis successfully predicts a sharp contraction in economic activity along with a modest and protracted decline in inflation following the rise in financial stress in the fourth quarter of 2008. The model does so even though inflation remains very dependent on the evolution of economic activity and of monetary ...
