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...

Despite the major advances in information technology that have shaped the recent wave of globalization, openness to trade is still a political choice, and trade policy can change with shifts in domestic political equilibria. This paper suggests that a particular threat and a limiting factor to...

This paper argues that openness to new, unconventional and disruptive ideas has a first-order impact on creative innovations-innovations that break new ground in terms of knowledge creation. After presenting a motivating model focusing on the choice between incremental and radical innovation,...

A key issue in current research and policy is the size of fiscal multipliers when the economy is in recession. We provide three insights. First, using regime-switching models, we find large differences in the size of spending multipliers in recessions and expansions with fiscal policy being...

We use rich historical data on military procurement spending across U.S. regions to estimate the effects of government spending in a monetary union. Aggregate military build-ups and draw- downs have differential effects across regions. We use this variation to estimate an "open economy relative...

We use data on a panel of states over a 30 year sample to estimate the response of unemployment to military procurement spending. The state panel provides greater variation in both variables and permits us to examine whether responses to procurement spending shocks vary across states. Our main...

In 1790, a U.S. paper dollar was widely held in disrepute (something shoddy was not 'worth a Continental'). By 1879, a U.S. paper dollar had become 'as good as gold.' These outcomes emerged from how the U.S. federal government financed three wars: the American Revolution, the War of 1812, and...

Do shocks to government spending raise or lower consumption and real wages? Standard VAR identification approaches show a rise in these variables, whereas the Ramey-Shapiro narrative identification approach finds a fall. I show that a key difference in the approaches is the timing. Both...

This paper analyzes the financial and war-spending policies of a state that faces a war in which defeat would result in the loss of sovereign power and in which the material consequences, conditional on avoiding defeat, are stochastic. The analysis takes explicit account of the historical...
