This paper studies the impact of aid volatility in a two-period model where production may occur with either a traditional or a modern technology. Public spending is productive and "time to build" requires expenditure in both periods for the modern technology to be used. The possibility of a...

This paper identifies factors associated with takeoff -- a sustained period of high growth following a period of stagnation. We examine a panel of 241 "stagnation episodes" from 146 countries, 54 % of these episodes are followed by takeoffs. Countries that experience takeoffs average 2.3% annual...

This paper studies the cross-country variation of the fiscal stimulus and the exchange rate adjustment propagated by the global crisis of 2008-9, identifying the role of economic structure in accounting for the heterogeneity of response. We find that greater de facto fiscal space prior to the...

The end of the great moderation has profound implications on the assessment of fiscal sustainability. The pertinent issue goes beyond the obvious increase in the stock of public debt/GDP induced by the global recession, to include the neglected perspective that the vulnerabilities associated...

We define the notion of a 'de facto fiscal space' of a country as the inverse of the tax-years it would take to repay the public debt. Specifically, we measure the outstanding public debt relative to the de facto tax base, where the latter measures the realized tax collection, averaged across...

This paper studies the patterns of fiscal stimuli in the OECD countries propagated by the global crisis. Overall, we find that the USA net fiscal stimulus was modest relative to peers, despite it being the epicenter of the crisis, and having access to relatively cheap funding of its twin...

This note shows that the aggregate fiscal expenditure stimulus in the United States, properly adjusted for the declining fiscal expenditure of the fifty states, was close to zero in 2009. While the Federal government stimulus prevented a net decline in aggregate fiscal expenditure, it did not...

This paper clarifies one of the puzzling results of the economic growth literature: the impact of military expenditure is frequently found to be non-significant or negative, yet most countries spend a large fraction of their GDP on defense and the military. We start by empirical evaluation of...
