Working Paper
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 ...

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 ...

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 ...

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.
