This paper studies a model of equilibrium unemployment in which the ecacy of scal policy increases markedly in times of crises. A sudden rise in pessimism leads households to save rather than to spend, causing a fall in output and rising unemployment But as a persistent rise in unemployment...

This paper argues that the effectiveness of fiscal policy may increase markedly during periods of low nominal interest rates and high, persistent, unemployment. An increase in government spending boosts economic activity and reduces the unemployment rate both in the present and in the future. As...

This paper provides a set of detailed estimated fiscal reaction functions for a panel of twenty industrialized countries, and it discusses commonalities and differences with regard to systematic fiscal policies across countries. In general, the countries in the panel adjust tax revenues strongly...

This paper surveys the link between imperfect competition and the effects of fiscal policy on output, employment and welfare. We examine static and dynamic models, with and without entry under a variety of assumptions using a common analytical framework. We find that in general there is a robust...

We consider the impact of anticipated policy changes when agents form expectations using adaptive learning rather than rational expectations. To model this we assume that agents combine limited structural knowledge with a standard adaptive learning rule. We analyze these issues using two...

Recent research and events have brought fiscal policy back into the spotlight. Fiscal Taylor rules and error correction models have represented two different ways of quantifying the feedbacks from fiscal and economic conditions to fiscal policy decisions. This paper synthesizes these two ideas,...
