Conventional wisdom in economic history suggests that conflict between countries can be enormously disruptive of economic activity, especially international trade. Yet nothing is known empirically about these effects in large samples. We study the effects of war on bilateral trade for almost all...

This article reviews the recent burgeoning political economics research on nation-building. We focus on three main aspects of this body of work. First, we discuss methodological issues related to measuring nation-building outcomes and provide a synthesis of studies that employ different...

This paper overviews theoretical and empirical contributions that study political borders from an economic perspective. It reviews theories of the number and size of nations focused on the trade-off between economies of scale in public-good provision and heterogeneity of preferences over public...

Wars of conquest and wars of independence are characterized by an asymmetric payoff structure: one party gets aggregate production if it wins, and its own production if it loses, while the other party gets only its own production if it wins, and nothing if it loses. We study a model of war with...

This paper studies how an increase in the number of armed groups operating within an area affects the amount of organized political violence. We use plausible exogenous variation in the number of armed groups in Pakistan, by exploiting the split of a major group due to the natural death of its...

This study examines the causal joint effect of a new political regime and war against Iraq on life expectancy of Iranians for the period 1978–1988 during the revolution and war. I use a synthetic control approach to construct a synthetic Iran based on a weighted average of other Middle East...

We analyze how trade openness matters for interstate conflict over productive resources. Our analysis features a terms-of-trade channel that makes security policies trade-regime dependent. Specifically, trade between two adversaries reduces each one's incentive to arm given the opponent's...

This study examines the home bias in trade in goods and services within the European Union. Using the newest release of the World Input Output database, available for the years 2000-2014, the effect is estimated using gravity regressions. The trade-reducing effect of borders is found to be...

We study how NAFTA changed the geography of violence in Mexico. We propose that this open border policy increased trafficking profits of Mexican cartels, resulting in violent competition among them. We test this hypothesis by comparing changes in drug-related homicides after NAFTA's introduction...

We argue that, under certain conditions, firms consider exports as a substitute for domestic demand. Our econometric model for six euro area countries suggests domestic demand and capacity constraints as additional variables for export equations. We apply the exponential and logistic variant of...
