This paper reviews the economics approach to conflict and national borders. The paper provides a summary of ideas and concepts from the economics literature on the size of nations; illustrates them within an analytical framework where populations engage in conflict over borders and resources,...

This paper provides a formal model of endogenous country formation and of choice of defense spending in a world with international conflict. The model is consistent with three observations. First, secessions and, more generally, break-up of countries should follow a reduction in the likelihood...

This paper shows that smaller countries have larger public sectors as a share of GDP, and are also more open to trade. These empirical observations are consistent with recent theoretical models explaining country formation and break up

Carbon intensity from fossil fuel use in the United States economy peaked in 1917. World War I ended, and the Spanish Flu pandemic broke out one year later in 1918. This paper contends that these events, coupled with associated turmoil in the domestic coal industry, were largely responsible for...

Recent studies based on 20th century US data conclude that abortion access raises children's average socioeconomic outcomes. We generalize a model of fertility, highlighting assumptions under which these abortion predictions can be reversed. Using 19th century abortion restrictions, we...

After an unprecedented number of banks suspended operations during the Panic of 1893, the head regulator of banks chartered by the United States government allowed about 100 banks to reopen after certifying their solvency. We evaluate whether actions by bank owners to change management, contract...

Using newly digitized data on the growth of the telegraph network in America during 1840-1852, the paper studies the impacts of the electric telegraph on national elections. I use proximity to daily newspapers with telegraphic connections to Washington to generate plausibly exogenous variation...

We study how the organization of the state evolves over the process of development of a nation, using a new dataset on the internal organization of the U.S. federal bureaucracy over 1817-1905. First, we show a series of facts, describing how the size of the state, its presence across the...

This paper develops an explanation for historical differences in the ways in which territorial disputes between sovereign states have been resolved. The main innovation in the analysis is to allow for three possible equilibria: ú an unfortified border; ú a fortified but peaceful border; and ú...

How does the interplay of geography and political-economic forces affect the shape of nations? This paper presents a quantitative framework for characterizing the equilibrium evolution of national boundaries in a world with a rich geography. The framework delivers simple equilibrium conditions...
