At the zero lower bound (ZLB), expectations about the future path of monetary or fiscal policy are crucial. We model expectations formation under level-k thinking, a form of bounded rationality introduced by García-Schmidt and Woodford (2019) and Farhi and Werning (2017), consistent with...

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...

What happens when fiscal and/or monetary policy changes systematically? We construct a DSGE model in which agents have to estimate fiscal and monetary policy rules and assess how uncertainty surrounding the conduct of policymakers influences transition paths after policy changes. We find that...

Did the Federal Reserve's Quantitative Easing (QE) in the aftermath of the financial crisis have macroeconomic effects? To answer this question, we estimate a large-scale DSGE model over the sample from 1998 until 2020, including data of the Fed's balance sheet. We allow for QE to affect the...

We investigate the e ect of monetary policy on European macroeconomic variables using a small-scale vector autoregression (VAR) and the "Effective Monetary Stimulus" (EMS). The EMS is a monetary policy metric obtained from yield curve data that is designed to consistently reflect the overall...

I propose a new term structure model for euro area real and nominal interest rates which explicitly incorporates a time-varying lower bound for nominal interest rates. Results suggest that the lower bound is of importance in structural analyses implying time-varying impulse responses of yield...

We propose an arbitrage-free shadow-rate term structure model to analyze the euro-area yield curve from 1999 to mid-2015, when bond yields turned negative at various maturities. In the model the 'shadow rate' can reach any positive or negative level, while the actual one-month rate cannot fall...

We analyse the effects of central bank government bond purchases in an estimated DSGE model for the euro area. In the model, central bank asset purchases are relevant in so far as agency costs distort banks' asset allocation between loans and bonds, and households face transaction costs when...

Occasionally binding constraints (OBCs) like the zero lower bound (ZLB) can lead to multiple equilibria, and so to belief-driven recessions. To aid in finding policies that avoid this, we derive existence and uniqueness conditions for otherwise linear models with OBCs. Our main result gives...
