We embed human capital-based endogenous growth into a New-Keynesian model with search and matching frictions in the labor market and skill obsolescence from long-term unemployment. The model can account for key features of the Great Recession: a decline in productivity growth, the relative...

This paper shows that the degree of competition affects the current account response to nominal shocks. The mechanism hinges on the relationship between the mark-up and the degree of real rigidity of prices. In a model with intermediate goods, the degree of real rigidity increases in the markup....

It is shown that a nominal rigidity may work as a natural mechanism for rational expectations endogenous fluctuations. By a nominal rigidity is meant that some nominal price, here the nominal wage rate, does not adjust within each short period to equate supply and demand (of labor), but adjusts...

A vast empirical literature has documented delayed and persistent effects of monetary policy shocks on output. We show that this finding results from the aggregation of output impulse responses that differ sharply depending on the timing of the shock: When the monetary policy shock takes place...

We estimate an optimization-based model with sticky prices alone (SP model) and one that combines nominal and real rigidities in the form of costly price and labor adjustments (NRR model) over the U.S. postwar time period. We then compare their ability to generate persistent, positive, responses...

This paper estimates whether learning-by-doing effects or cleansing effects of recessions drive the endogenous component of productivity in the United States. Using Bayesian estimation techniques we find that external and internal learning-by-doing effects dominate. We find no evidence for...

When learning-by-doing is at the origin of growth, we show that growth rates should be negatively related to the amplitude of the business cycle if the growth rate in human capital is increasing and concave in the cyclical component of production. Empirical evidence strongly supports this...

The productivity slowdown faced by the US economy since the first oil shock has been associated with a rise in the decline rate of the relative price of equipment and a reduction in the rate of disembodied technical change. We build up a growth model in which learning-by-doing is the engine of...
