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 presents a data set that improves the measurement of educational attainment for a broad group of countries. We extend our previous estimates of educational attainment for the population over age 15 and over age 25 up to 1995 and provide projections for 2000. We discuss the estimation...

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...

Our panel data set on educational attainment has been updated for 146 countries from 1950 to 2010. The data are disaggregated by sex and by 5-year age intervals. We have improved the accuracy of estimation by using information from consistent census data, disaggregated by age group, along with...

For U.S. annual data that include WWII, the estimated multiplier for temporary defense spending is 0.4-0.5 contemporaneously and 0.6-0.7 over two years. If the change in defense spending is "permanent" (gauged by Ramey's defense-news variable), the multipliers are higher by 0.1-0.2. The...

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...

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...

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...

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...

Optimal debt management can be thought of in three stages. First, if taxes are lump sum and the other conditions for Ricardian equivalence hold, then the division of government financing between debt and taxes is irrelevant, and the whole level of public debt is indeterminate from an optimal-tax...
