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 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...

This paper proposes a method for computing tax rates using national accounts and revenue statistics. Using this method we construct time-series of tax rates for large industrial countries. The method identifies the revenue raised by different taxes at the general government level and defines...

Recent quantitative studies predict large welfare gains from reducing tax distortions in a closed economy, despite costly transitional dynamics to more efficient tax systems. This paper examines transitional dynamics and gains of tax reforms for countries in a global economy, and provides...

Governments in emerging markets often behave like a "tormented insurer," trying to use non-state-contingent debt instruments to avoid cuts in payments to private agents despite large fluctuations in public revenues. In the data, average public debt-GDP ratios decline as the variability of...

This paper looks at fiscal solvency and public debt sustainability in both emerging market and advanced countries. Evidence of fiscal solvency, in the form of a robust positive conditional relationship between public debt and the primary fiscal balance, is established in both groups of...
