Negative interest rates remain a controversial policy for central banks. We study a novel signalling channel and ask under what conditions negative rates should exist in an optimal policymaker’s toolkit. We prove two necessary conditions for the optimality of negative rates: a time-consistent...

We examine the credit channel of monetary policy from 2000 to 2015 in the Euro Area using daily monetary policy shock and credit risk measures in an autoregressive distributed lag model. We find that an expansionary monetary policy shock leads to a short-run increase in the credit risk of...

We develop a New Keynesian model with household heterogeneity and bounded rationality in the form of cognitive discounting. The interaction of household heterogeneity and bounded rationality generates amplification of monetary and fiscal policy through indirect general equilibrium effects while...

This paper studies the effects of harmonizing collateral policy in a monetary union. In 2007, the European Central Bank replaced national collateral lists with a single list specifying which assets euro area banks can pledge as collateral. Banks holding newly eligible assets experience a...

Exploiting the heteroscedasticity of the changes in short-term and long-term interest rates and exchange rates around the FOMC announcement, we identify three structural monetary policy shocks. We eliminate the predictable part of the shocks and study their effects on financial variables and...

This paper first shows that, contrary to conventional wisdom, the European Central Bank (ECB) can influence global energy prices. Second, through Lucas critique-robust counterfactual analysis, we uncover that the ECB's ability to affect fast-moving energy prices plays an important role in the...

Using a data-driven approach to identify structural vector autoregressive models, we examine key factors influencing the US dollar exchange rate across eight advanced economies from 1980 to 2022. We find that shocks to inflation expectations, which are closely tied to unfunded government...

This study examines whether central banks can combat inflation that is caused by rising energy prices. By using a high-frequency event study and a Structural Vector Autoregression, we find evidence that the European Central Bank (ECB) and the Federal Reserve (Fed) are capable of doing so by...

How does a monetary union alter the impact of business cycle shocks at the household level? We develop a Heterogeneous Agent New Keynesian model of two countries (HANK2) and show in closed form that a monetary union shifts the adjustment to a shock horizontally - across countries - within the...

We examine the causal relationship between US monetary policy shocks, exchange rates and currency excess returns for a sample of eight advanced countries over the period 1980M1 to 2022M11. We find that the dynamics of the US dollar exchange rate is the main driver of currency excess returns. The...
