We show that the transmission of the European Central Bank’s (ECB) recent monetary policy tightening differs across banks depending on their level of excess reserves. Specifically, the net worth of reserve-rich banks may display a boost when the interest rate paid on reserves increases...

How do real interest rates affect financial fragility? We study this issue in a model in which bank borrowing is subject to rollover risk. A bank’s optimal borrowing trades off the benefit from investing additional funds into profitable assets with the cost of greater risk of a run by bank...

This paper shows that the supply side of credit is a major factor for the phenomenonof hampered interest rate pass-through in monopolistic banking markets. Our data,covering all 1,555 small and medium sized banks in Germany, provides a clear wayto partial out demand shocks; we are thus able to...

We revisit the reversal puzzle: A counterintuitive contraction of inflation in response to an interest rate peg. We show that it is intimately related to the degree of agents' anticipation. If agents perfectly anticipate the peg, reversals occur depending on the duration of the peg. If they do...

We analyze the macroeconomic implications of a transient interest-rate peg in combination with a QE program in a non-linear medium-scale DSGE model. In this context, we re-examine what has become known as the reversal puzzle (Carlstrom, Fuerst and Paustian, 2015) and provide an analytical...

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...

We study whether a central bank should deviate from its objective of price stability to promote financial stability. We tackle this question within a textbook New Keynesian model augmented with capital accumulation and microfounded endogenous financial crises. We compare several interest rate...

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...

Could a monetary policy loosening in a low interest rate environment have unintended recessionary effects? Using a non-linear macroeconomic model fitted to the euro area economy, we show that the effectiveness of monetary policy can decline in negative territory until it reaches a turning point,...

We investigate German banks' exposure to interest rate risk. In finance, higher demand for a risky asset is typically associated with higher expected return. However, employing a utility function which implies both risk-averse and risk-seeking behavior depending on the level of profits, we show...
