On the Economic Mechanics of Warfare
The literature on war deals with finances, causes, or consequences. But, how do war-related expenditures affect economically-relevant outcomes at a war’s conclusion (e.g., prevailing side, duration, and casualties)? I present a model of attrition and characterize the effects of GDP at a military conclusion (one side cannot fight anymore) and a political conclusion (one side quits). The estimated model fits the data for the battle of Iwo Jima well. Analyzing data for the current Russo-Ukrainian war through the lenses of the model suggests that additional support to Ukraine could yield a ...

The effects of government spending on real exchange rates: evidence from military spending panel data
Using panel data on military spending for 125 countries, we document new facts about the effects of changes in government purchases on the real exchange rate, consumption, and current accounts in both advanced and developing countries. While an increase in government purchases causes real exchange rates to appreciate and increases consumption significantly in developing countries, it causes real exchange rates to depreciate and decreases consumption in advanced countries. The current account deteriorates in both groups of countries. These findings are not consistent with standard ...

On the Economic Mechanics of Warfare
A large literature is concerned with war finance, but there is little by way of understanding how war-related expenditures affect the economically-relevant outcomes of wars, e.g., prevailing side, duration, or destruction and casualties. I present a model of attrition in which I characterize the effects of resources on the outcomes of war for a military conclusion (when one side cannot fight anymore) and a political conclusion (when one side does not want to fight anymore). I discuss the role of GDP for both types of conclusion. I also analyze the mechanics of third-party support to a small ...

Fiscal multipliers in advanced and developing countries: evidence from military spending
Using novel data on military spending for 129 countries in the period 1988?2013, this paper provides new evidence on the effects of government spending on output in advanced and developing countries. Identifying government-spending shocks with an exogenous variation in military spending, we estimate one-year fiscal multipliers in the range 0.75-0.85. The cumulative multipliers remain significantly different from zero within three years after the shock. We find substantial heterogeneity in the multipliers across groups of countries. We then explore three potential sources leading to ...

On the Economic Mechanics of Warfare
A large literature is concerned with the consequences of war-related expenditures and how to finance them. Yet, there is little by way of understanding how expenditures affect the outcomes of wars, e.g., prevailing side, duration, or total destruction. I present a model of attrition in which I characterize the effects of resources on the outcomes of war for a military conclusion (when one side cannot fight anymore) and a political conclusion (when one side does not want to fight anymore). I discuss the role of GDP for both types of conclusions. I also analyze the mechanics of third-party ...

Output response to government spending: evidence from new international military spending data
Fiscal policy, among other measures, was widely used to stimulate employment and to put the U.S. economy back on track in response to the Great Recession and in a number of previous recessions in both the United States and in Europe. It is striking how much disagreement there was ? and still is ? among policymakers and academics alike about the inner workings of fiscal policy and its effect on output and employment. Estimating fiscal multipliers is methodologically challenging, as government spending often reacts to current or anticipated changes in economic conditions, and requires bold ...

On the Economic Mechanics of Warfare
How do war-related expenditures affect economically-relevant outcomes at a war’s conclusion (e.g., prevailing side, duration, and casualties)? I present a model of attrition and characterize the effects of resources at a military conclusion (one side cannot fight anymore) and a political conclusion (one side quits). I analyze the Pacific War through the lenses of the model both theoretically and empirically. I find that a parsimonious parameterization reproduces well the aggregate patterns of destruction, measured in ship tonnage, for both belligerents.
