We generalize a simple New Keynesian model and show that a flattening of the Phillips curve reduces the size of fiscal multipliers at the zero lower bound (ZLB) on the nominal interest rate. The factors behind the flatting are consistent with micro- and macroeconomic empirical evidence: it is a...

In this paper, we reconsider the question how monetary policy influences exchange rate dynamics. To this end, a vector autoregressive (VAR) model is combined with a two-country dynamic stochastic general equilibrium (DSGE) model. Instead of focusing exclusively on how monetary policy shocks...

We study the asset-pricing implications of changes in the variety of consumption goods which happens through free entry and exit of rms. Fluctuations in varieties drive a wedge between the measured and model-based (including variety growth) consumer price index making the pricing kernel as well...

We explore the natural rate of interest, shortly r ∗ , in emerging economies. If economic growth originates from convergence, then growth, say, from technological progress will be lower than we find in the data and, hence, r ∗ will be lower. Ignoring convergence upwardly biases our estimates...
