Interest rates on public debt have for several years now fallen short of GDP growth rates in much of the Western world. In his presidential address to the AEA Blanchard argued that this implies that there are no fiscal costs to high debt (Blanchard, 2019).1 In this paper we argue that the safe...

We study optimal government spending in a business cycle model with frictional unemployment. The Ramsey optimal policy is contrasted with a reference policy which would be first best in a frictionless economy. Results are: the Ramsey policy i) implies a higher steady state ratio of government...

This paper provides new evidence on the effects of government spending shocks and the fiscal transmission mechanism in the euro area for the period 1980-2008. Our contribution is two-fold. First, we investigate changes in the macroeconomic impact of government spending shocks using time-varying...

This paper assesses the transmission of fiscal policy shocks in a New Keynesian framework where government expenditures contribute to aggregate production. It is shown that even if the impact of government expenditures on production is small, this assumption helps to reconcile the models'...

Conventional wisdom teaches that the output response upon a fiscal expansion is higher under fixed than floating exchange rates for a small open economy. We analyse the effects of fiscal expansions using a New Keynesian model and find that this result reverses in times of sovereign default risk....

The most recent literature on aid effectiveness finds a positive effect of aid on growth. To the extent that aid goes through the budget, this either reflects an aid-financed increase in government expenditures (quantity effect) or an improvement in the use of government resources as a result of...

The potential interactions among fiscal policies, investments and economicgrowth are complex and manifold.In this paper, we will perform a systematic comparative analysis of the variouseconomic insights that arecurrently available on these complex relationships, both theoretically (by aselective...

The issue of whether the public sector enhances or retards long-run economic growth has been debated passionately in recent years. In this paper we use meta-analysis to shed light on the issue. A sample of 93 published studies, yielding 123 meta-observations, is used to examine the robustness of...
