Standard New Keynesian models deliver puzzling results at the effective lower bound of short-term interest rates: greater price flexibility amplifies the fall in output in response to adverse demand shocks; labour tax cuts are contractionary; the multipliers of wasteful government spending are...

We document that UK government bond yields systematically rise in a two-day window before Monetary Policy Committee (MPC) meetings, which we refer to as pre-MPC windows. The effect concentrates on pre-MPC windows that coincide with new issuance of government bonds. Decomposing the effect into an...

When the economy is in a liquidity trap and households have a precautionary motive to save against unemployment risk, adverse demand shocks cause severe deflationary spirals and output contractions. In this context, we study the implications of optimal monetary policy, which consists of keeping...

This paper uses kernel methods to estimate a seven variable time-varying (TV) vector autoregressive (VAR) model on the US data set constructed by Smets and Wouters. We use an indirect inference method to map from this TV VAR to time variation in implied Dynamic Stochastic General Equilibrium...

We examine whether emerging market prudential policies offset the macro-financial spillover effects of US monetary policy. We find that emerging markets with tighter overall prudential policy face significantly smaller, and less negative, spillovers to total credit from US monetary policy...

Long-term asset purchases carried out by central banks increase the consumption volatility of households holding long-term debt. For this reason, monetary authorities should not just aim at stabilising inflation and the output gap but also mitigate the volatility of their balance sheet. In...

The existence of and uncertainty about structural change in the economy are important features facing policymakers. This paper considers the implications for policy design of uncertainty about structural change, modelling the time variation in parameters of forward-looking models as Markov...

This paper develops a model featuring both a macroeconomic and a financial friction that speaks to the interaction between monetary and macroprudential policy and to the role of US monetary and regulatory policy in the run up to the Great Recession. There are two main results. First, real...

This paper revisits the paradox of flexibility, i.e., the result that, in a liquidity trap, greater price flexibility amplifies output volatility in response to negative demand shocks. We argue this paradox is the consequence of a failure of standard models to correctly characterize monetary...
