Thomas Piketty's (2014) book, Capital in the 21st Century, follows in the tradition of the great classical economists, like Marx and Ricardo, in formulating general laws of capitalism to diagnose and predict the dynamics of inequality. We argue that general economic laws are unhelpful as a guide...

Abraham Lincoln's election produced Southern secession, Civil War, and abolition. Using a new database of slave sales from New Orleans, we examine the connections between political news and the prices of slaves for 1856-1861. We find that slave prices declined by roughly a third from their 1860...

We analyze how secession movements unfold and the interdependence of regions' decisions to secede. We first model and then empirically examine how secessions can occur sequentially because the costs of secession decrease with the number of seceders and because regions update their decisions...

Trade liberalization and political separatism go hand in hand. In a world of trade restrictions, large countries enjoy economic benefits because political boundaries determine the size of the market. In a world of free trade and global markets even relatively small cultural, linguistic or ethnic...

This paper analyzes whether the propensity to secede by subnational regions responds mostly to differences in income per capita or to distinct identities. We explore this question in a quantitative political economy model where people's willingness to finance a public good depends on their...

This paper proposes a new method to measure ethnolinguistic diversity and offers new results linking such diversity with a range of political economy outcomes -- civil conflict, redistribution, economic growth and the provision of public goods. We use linguistic trees, describing the...

Most nations have experienced an internal armed conflict since 1960. The past decade has witnessed an explosion of research into the causes and consequences of civil wars, belatedly bringing the topic into the economics mainstream. This article critically reviews this interdisciplinary...

This paper investigates the extent of vengeful feelings and their determinants using data on more than 89,000 individuals from 53 countries. Country characteristics (such as per-capita income, average education of the country, presence of an armed conflict, the extent of the rule-of-law,...

In the past decade, nearly 20 studies have found a strong, persistent pattern in surveys and behavioral experiments from over 40 countries: individual exposure to war violence tends to increase social cooperation at the local level, including community participation and prosocial behavior. Thus...

Until recently, neither climate nor conflict have been core areas of inquiry within economics, but there has been an explosion of research on both topics in the past decade, with a particularly large body of research emerging at their intersection. In this review, we survey this literature on...
