This paper is based on presentation given at the June 2011 Conference of the Centre for Growth and Business Cycle Research at the University of Manchester. It reviews key features of the 2007-08 financial crisis, the subsequent 'great recession' and the European public debt problems; in the...

This paper examines how supply-side policies may play a role in fighting a low aggregate demand that traps an economy at the zero lower bound (ZLB) of nominal interest rates. Future increases in productivity or reductions in mark-ups triggered by supply-side policies generate a wealth effect...

This paper analyses two-way interactions between structural reform and macroeconomic policy. If structural reforms increase the flexibility of labour markets, they are likely to improve the short-run inflation-unemployment trade-off, providing an incentive for policy-makers to expand aggregate...

The Paper studies the inflation rate associated with optimal monetary policy in a standard suite of DSGE models, when fiscal policy is either unrestricted optimal or restricted but supportive of monetary policy. Full nominal price flexibility, nominal prices set one period in advance and...

Motivated by the recent experience of the U.S. and the Eurozone, we describe the quantitative properties of a New Keynesian model with a zero lower bound (ZLB) on nominal interest rates, explicitly accounting for the nonlinearities that the bound brings. Besides showing how such a model can be...

Shocks to the marginal efficiency of investment are the most important drivers of business cycle fluctuations in US output and hours. Moreover, these disturbances drive prices higher in expansions, like a textbook demand shock. We reach these conclusions by estimating a DSGE model with several...

We estimate a New-Neoclassical Synthesis business cycle model with two investment shocks. The first, an investment-specific technology shock, affects the transformation of consumption into investment goods and is identified with the relative price of investment. The second shock affects the...

We study the effects of changes in uncertainty about future fiscal policy on aggregate economic activity. Fiscal deficits and public debt have risen sharply in the wake of the financial crisis. While these developments make fiscal consolidation inevitable, there is considerable uncertainty about...

We examine the impact of fiscal policy interventions in an environment where the short term nominal interest rate is at the zero bound. In the basic New Keynesian model in which the monetary authority operates a Taylor rule, globally multiple equilibria arise, some of which display all the...

We study the effect of regional expenditure and revenue shocks on price dispersion in a monetary union using annual US state and quarterly EU data. We identify fiscal shocks using sign restrictions on the dynamics of expenditures, revenues, deficits and output. We construct two estimates for...
