This paper uses a DSGE model to examine the effects of an expansion in government spending in a liquidity trap. The spending multiplier can be much larger than in the normal situation if the liquidity trap is very prolonged, and the budgetary costs minimal. But given this "fiscal free lunch," it...

We examine global economic dynamics under infinite-horizon learning in a New Keynesian model in which the interest-rate rule is subject to the zero lower bound. As in Evans, Guse and Honkapohja (2008), we find that under normal monetary and fiscal policy the intended steady state is locally but...

In this Paper, we analyse the implications of price setting restrictions for the conduct of cyclical fiscal and monetary policy. We consider an environment with monopolistic competitive firms, a shopping time technology, prices set one period in advance, and government expenditures that must be...

This paper contains a selective review of some of the key fiscal issues faced by transition economies. The twelve countries that provide the empirical background for this study have all been under Fund programmes for at least some of the time since they initiated their transitions from plan to...

A new theory of price determination suggests that if primary surpluses are independent of the level of debt, the price level has to ‘jump’ to assure fiscal solvency. In this regime (which we call fiscal dominant), monetary policy has to work through seignorage to control the price level. If,...

Leith and Wren-Lewis (2007) have shown that government debt is returned to its pre-shock level in a New Keynesian model under optimal discretionary policy. This has two important implications for monetary and fiscal policy. First, in a high-debt economy, it may be optimal for discretionary...

This survey outlines the general lessons of the recent literature on imperfectly competitive macroeconomies for the theory of monetary and fiscal policy. A general framework is presented which encompasses most of the existing literature. Although money is of itself neutral in these models, the...

We lay out a tractable model for fiscal and monetary policy analysis in a currency union, and analyse its implications for the optimal design of such policies. Monetary policy is conducted by a common central bank, which sets the interest rate for the union as a whole. Fiscal policy is...

The literature argues that the benefits of an independent Central Bank accrue at no cost to the real side. In this paper, we argue that the lack of correlation between monetary autonomy and output variability is due to the proactive role of fiscal policy when faced with rigid monetary...

We build a New Keynesian model of the business cycle with sticky prices and real wage rigidities motivated by efficiency wages of the gift exchange variety. Compared to a standard sticky price model, our Fair Wage model provides an explanation for structural employment and generates more...
