This article investigates the effect of natural resources on whether ethno-political groups choose to pursue their goals with non-violent as compared to violent means, distinguishing terrorism from insurgencies. It is hypothesized that whether or not the extraction of fossil fuels sparks...

According to the Framework Convention on Climate Change, global collective action is needed to stabilize “greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous [our emphasis] anthropogenic interference with the climate system.” The Framework Convention thus...

Previous research shows that collective action to avoid a catastrophic threshold, such as a climate "tipping point," is unaffected by uncertainty about the impact of crossing the threshold but that collective action collapses if the location of the threshold is uncertain. Theory suggests that...

To understand the effects of trade policy uncertainty on firm-level export decisions, we study firm-product data on Chinese exports to the U.S. in the years surrounding China’s 2001 WTO accession. Following predictions based on a model of heterogeneous firms, we provide empirical evidence that...

We study the effects of financial sanctions on cross-border credit supply. Using a differences-in-differences approach to analyze eleven sanctions episodes between 2002 and 2015, we find that banks located in Germany reduce their positions in countries with sanctioned entities by 38%. The...

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...

In an interconnected world, economic and political interests inevitably reach beyond national borders. Since policy choices generate external economic and political costs, foreign state and non-state actors have an interest in inflencing policy actions in other sovereign countries to their...

How effective are “smart” sanctions in imposing costs on an adversary? We consider this question in a model where a targeted regime may choose to “shield” strategically important firms from harm. Using detailed firm and individual data, we estimate the impact on firm performance from...

Using a new, global data base covering the years 1950 to 2015, we study the impact of sanctions on international trade and welfare. We make use of the rich dimensionality of our data and of the latest developments in the structural gravity literature. Starting with a broad evaluation by sanction...

Fiscal deficits, elevated debt-to-GDP ratios, and high inflation rates suggest hyperinflation could have potentially emerged in many European countries after World War I. We demonstrate that economic policy uncertainty was instrumental in pushing a subset of European countries into...
