We provide a Keynesian growth theory in which pessimistic expectations can lead to very persistent, or even permanent, slumps characterized by unemployment and weak growth. We refer to these episodes as stagnation traps, because they consist in the joint occurrence of a liquidity and a growth...

Growth takeoffs in developing economies have rebounded in the past two decades. Although recent takeoffs have lasted longer than takeoffs before the 1990s, a key question is whether they could unravel like some did in the past. This paper finds that recent takeoffs are associated with stronger...

Empirical evidence suggests that recessions have long-run effects on the economy's productive capacity. Recent literature embeds endogenous growth mechanisms within business cycle models to account for these "scarring" effects. The optimal conduct of monetary policy in these settings, however,...

This paper studies fiscal policy in a New Keynesian DSGE model with endogenous technology growth in which scarring can occur endogenously through hysteresis effects in TFP. Both demand- and supply-driven recessions can weaken investment in R&D and technology adoption, thus depressing the...

This paper studies fiscal policy in a New Keynesian DSGE model with endogenous technology growth in which scarring can occur endogenously through hysteresis effects in TFP. Both demand- and supply-driven recessions can weaken investment in R&D and technology adoption, thus depressing the...

Extended periods of ultra-easy monetary policy in advanced economies have rekindled debates about the zombification of weak companies and its impact on resource allocation, economic growth, inflation, and financial stability. Using both firm-level and macroeconomic data, we find that recessions...

We introduce endogenous growth in an otherwise standard NK model with staggered prices and wages. Some results follow: (i) monetary volatility negatively affects long-run growth; (ii) the relation between nominal volatility and growth depends on the persistence of the nominal shocks and on the...

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....

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...
