Questions about current and prior religion adherence from the International Social Survey Program and the World Values Survey allow us to calculate country-level religious-conversion rates for 40 countries. These conversion rates apply to religion adherence classified into eight major types. In...

U.S. stock volatility is 33 percent lower during wartime and periods of conflict. This is true even for World Wars I and II, which would seemingly increase uncertainty. In a seminal paper, Schwert (1989) identified the "war puzzle" as one of the most surprising facts from two centuries of stock...

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 study the effects of the liberty bond drives of World War I on financial intermediation in the 1920s and beyond. Using panel data on U.S. counties we find that higher liberty bond subscription rates led to an increase in the number of investment banks, stronger local competition between...

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...

Military spending, fatalities, and the destruction of capital, all of which are immediately felt and are often large, are the most overt costs of war. They are also relatively short-lived. The costs of war borne by combatants and their caretakers, which includes families, communities, and the...

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...

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...

The occupation payments made by France to Nazi Germany between 1940 and 1944 represent one of the largest recorded international transfers and contributed significantly to financing the overall German war effort. Using a neoclassical growth model that incorporates essential features of the...
