We show that if business cycles are driven by financial shocks, the interplay between the effective lower bound (ELB) and the costs of external financing can generate an additional supply-side channel, which causes a disconnect between inflation and output. In normal times, factor costs dominate...

This paper presents optimal rules for monetary policy in Brazil derived from a backward looking expectation model consisting of a Keynesian IS function and an Augmented Phillips Curve (IS-AS). The IS function displays a high sensitivity of aggregate demand to the real interest rate and the...

We build a two-country version of the model in Gali & Monacelli (2005), which extends for a small open economy the new Keynesain DSGE model used as tool for monetary policy analysis in closed economies. A distinctive feature of the model is that the terms of trade enters directly into the new...

This paper proposes a tractable financial accelerator New Keynesian DSGE modelthat allows for closed-form solutions. In the presence of financial frictions, theNew Keynesian Phillips curve features a flat slope with respect to the output gapand is strongly forward-looking. All shocks cause...

Central banks wish to avoid self-fulfilling fluctuations. Monetary rules with a unit response to real rates achieve this under the weakest possible assumptions about the behaviour of households and firms. They are robust to household heterogeneity, hand-to-mouth consumers, non-rational...

Short answer: It helps a lot when other important variables are excluded from the information set. Longer answer: We revisit claims in the literature that money growth is Granger-causal for inflation at low frequencies. Applying frequency-specific tests in a comprehensive system setup for...
