This paper derives restrictions on monetary and fiscal policies for determinate equilibria in a two-country monetary union with autarkic members. It finds that a central bank following the Taylor principle may not be sufficient for determinacy unless accompanied by one 'active' fiscal authority...

I characterize optimal monetary and fiscal policy in a stochastic New Keynesian model when nominal interest rates may occasionally hit the zero lower bound. The benevolent policymaker controls the short-term nominal interest rate and the level of government spending. Under discretionary policy,...

This paper presents the novel implications of introducing price rigidities into a model of good-specific habit formation, for the response of private consumption following a positive government spending shock. With 'deep' habits in demand, the price elasticity of demand rises after the fiscal...

This paper investigates the implications for the nominal exchange rate of a Border Tax Adjustment (BTA) when there is BTA neutrality. A border tax adjustment is a change from an origin-based system of taxation, that taxes exports but exempts imports to a destination-based system that taxes...

In this paper we review and extend some of the key lessons that seem to be emerging from the Ramsey-inspired theory of dynamic optimal monetary and fiscal policies. We construct measures of the key distortions in our economy; we label these 'dynamic wedges'. Inflation, actual or anticipated,...

What is the relation between infrequent price adjustment and the dynamic response of the aggregate price level to monetary shocks? The answer to this question ranges from a one-to-one-link (Calvo, 1983) to no connection whatsoever (Caplin and Spulber, 1987). The purpose of this paper is to...

The paper studies the macroeconomic effects of government spending shocks in an economy characterized by positive trend growth. It shows that the lower is the trend growth rate the less inflationary are government spending shocks and vice versa. Moreover, on impact output is higher but exhibits...

This paper discusses fiscal policy using a DSGE model with search and matching in the labour market. Fiscal policy is effective mainly via its impact through the labour market. Although public intervention tends to crowd out private consumption, public spending also improves the matching between...

In this paper we show that empirically plausible results on the effects of fiscal shocks in Galí, López-Salido and Vallés (2007) rely on a high degree of price stickiness and a large percentage of financially constrained agents. Real rigidities in the form of habit persistence, fixed...
