In this paper, we use a dynamic stochastic general equilibrium model to examine the effects of an expansion in government spending in a liquidity trap. If the liquidity trap is very prolonged, the spending multiplier can be much larger than in normal circumstances, and the budgetary costs...

Galí's innovative approach of imposing long-run restrictions on a vector autoregression (VAR) to identify the effects of a technology shock has become widely utilized. In this paper, we inves-tigate its reliability through Monte Carlo simulations using calibrated business cycle models. Overall,...

This paper synthesises the implications of recent statistical evidence regarding inflation persistence in the euro area. For aggregate data, the degree of inflation persistence appears to be very high for sample periods spanning multiple decades but falls dramatically once we allow for time...

This paper evaluates new evidence on price-setting practices and inflation persistence in the euro area with respect to its implications for macro modeling. It argues that several of the most commonly used assumptions in micro-founded macro models are seriously challenged by the new findings....

We investigate the extent to which inflation expectations have been more firmly anchored in the United Kingdom-a country with an explicit inflation target-than in the United States-a country with no such target-using the difference between far-ahead forward rates on nominal and inflation-indexed...
