How can the impact of aid be estimated in the presence of fungibility? And how far does fungibility reduce its benefits? These questions are analyzed in a context where a donor wants to target its efforts on a specific sector and specific geographic areas. A traditional...

This paper considers budget expansions and adjustments in OECD countries in the last three decades. Our main results are: i) on average fiscal expansions are the results of increases in expenditures, particularly of transfer programs, while contractions are typically due to tax increases; ii)...

The present paper argues that the correct experiment to evaluate the effects of a fiscal adjustment is the simulation of fiscal plans rather than of individual fiscal shocks. The simulation of the fiscal plans adopted by 16 OECD countries over a 30-year period supports the hypothesis that the...

Several recent studies suggest that the response of national saving to fiscal policy may be non-linear. In this paper we use two data sets to search for the circumstances in which such non-linear responses may arise: a sample of OECD countries used in previous studies, and sample of developing...

This paper characterizes the dynamic effects of shocks in government spending and taxes on economic activity in the United States in the post-war period. It does so by using a mixed structural VAR/event study approach. Identification is achieved by using institutional information about the tax...

We consider public debt from a long-term historical perspective, showing how the purposes for which governments borrow have evolved over time. Periods when debt-to-GDP ratios rose explosively as a result of wars, depressions and financial crises also have a long history. Many of these episodes...

We estimate the effects of fiscal policy on the labor market in US data. An increase in government spending of 1 percent of GDP generates output and unemployment multipliers respectively of about 1.2 per cent (at one year) and 0.6 percentage points (at the peak). Each percentage point increase...

We document that variations in government purchases generate a rise in consumption, the real and the product wage, and a fall in the markup. This evidence is robust across alternative empirical methodologies used to identify innovations in government spending (structural VAR vs. narrative...

This paper summarizes the results of a large recent literature on multi year fiscal plans for deficit reduction (austerity). The key results are that deficit reduction policies based upon spending cuts are much less costly in terms of short run output losses than tax based adjustments. On...

Government spending at the zero lower bound (ZLB) is not necessarily welfare enhancing, even when its output multiplier is large. We illustrate this point in the context of a standard New Keynesian model. In that model, when government spending provides direct utility to the household, its...
