Rational expectations are often used as a strong argument against policy activism, as they may undermine or neutralize the policymaker’s actions. Although this sometimes happens, rational expectations do not always imply policy invariance or ineffectiveness. In fact, in certain circumstances...

This note comments on two central issues for fiscal policy design in the United Kingdom, highlighted in the recent ‘Code for Fiscal Stability’ proposed by the new Labour government. The first concerns the merits of the so-called ‘golden rule of public sector investment’ – the...

Does an inflation conservative central bank à la Rogoff (1985) remain desirable in a setting with endogenous fiscal policy? To provide an answer we study monetary and fiscal policy games without commitment in a dynamic stochastic sticky price economy with monopolistic distortions. Monetary...

We show that the composition of government spending influences the long-run behaviour of the real exchange rate. We develop a two-sector small open economy model in which an increase in government consumption is associated with real appreciation, while an increase in government investment may...

In this paper we assess to what extent in the existence of a financial crisis, government spending can contribute to mitigate economic downturns in the short run and whether such impact differs in crisis and non crisis times. We use panel analysis for a set of OECD and non-OECD countries for the...

The new generation of dynamic stochastic general equilibrium (DSGE) models seems particularly suited for conducting scenario analysis. These models formalise the behaviour of economic agents on the basis of explicit micro-foundations. As a result, they appear less prone to the Lucas critique...

The paper offers a survey of recent research on fiscal policy in both deterministic and stochastic models of the New Open Economy Macroeconomics (NOEM) initiated by Obstfeld and Rogoff (1995, 2002b). The survey includes a comparison of the implications of the deterministic benchmark model to the...

Measuring the effects of discretionary fiscal policy is both difficult and controversial, as some explicit or implicit identifying assumptions need to be made to isolate exogenous and unanticipated changes in taxes and government spending. Studies based on structural vector autoregressions...

This paper explores different fiscal stimuli within a business cycle model with an endogenous number of firms. We demonstrate that a changing number of firms is a crucial dimension for evaluating fiscal policy since it accelerates the impacts of fiscal policy. In the presence of demand stimuli...

Do public sector wages exert presures on private sector wages, or has private sector a leadership role in wage setting?. This paper tries to isolate the pure signalling effect that one sector might exert on the other by controlling for other determinants of wages (prices, productivity,...
