How should monetary and fiscal policy react to adverse financial shocks? If monetary policy is constrained by the zero lower bound on the nominal interest rate, subsidising the interest rate on loans is the optimal policy. The subsidies can mimic movements in the interest rate and can therefore...

Central banks have responded with exceptional vigour to the crisis by using their traditional interest-rate tools to their limits and deploying a wide range of unconventional measures. This paper documents these responses in a systematic way, reviews the evidence about their impact, and...

The quantitative significance of shocks to the financial intermediary (FI) has not received much attention up to now. We estimate a DSGE model with what we describe as chained credit contracts, using Bayesian technique. In the model, credit-constrained FIs intermediate funds from investors to...

This paper investigates the existence of significant spillovers from the housing sector onto the wider economy for eight OECD countries in a six-variable structural vector autoregressive model (SVAR). A housing demand shock is identified through the recursive Choleski decompostion and,...

This paper studies empirically the dynamic interactions between asset prices, monetary policy, and aggregate fluctuations in the U.S. during the Volcker–Greenspan period. Results from a simple structural vector autoregression indicate that monetary policy reacts directly to the term spread and...

This paper investigates the existence of significant spillovers from the housing sector onto the wider economy for the seven major OECD countries using Uhlig's (2005) agnostic identification procedure. This method allows a housing demand shock to be identified in a six-variable VAR model by...

We show that firms' nominal required returns to capital (i.e., their discount rates) are sticky with respect to expected inflation. Such nominally sticky discount rates imply that increases in expected inflation directly lower firms' real discount rates and thereby raise real investment. We...

The European Central Bank is unique in setting monetary policy for several sovereign states with heterogeneous debt levels and different maturity structures. The monetary-fiscal nexus is central to the functioning of the euro area. We focus on one particular aspect of that nexus, the effect the...

I discuss private and central-bank-issued digital currencies, summarizing my prior research. I argue that prices of private digital currencies such as bitcoin follow random walks or, more generally, risk-adjusted martingales. For central bank digital currencies, I argue that they enhance the...
