Group-based identity undermines democracy by impeding democratic change of government. A substantial literature has therefore studied how to make democracy consistent with group identity. We contribute to this literature by introducing the role of group decisiveness into voting incentives and...

This study quantifies the economic impacts of SARS on the four affected Asian economies and the two most affected Chinese regions using synthetic control methods with macroeconomic and remote-sensing nightlight data. For the four affected economies (China, Hong Kong, Taiwan, and Singapore), we...

This paper studies the effects of bilateral foreign aid on conflict escalation and de-escalation. We make three major contributions. First, we combine data on civil wars with data on low level conflicts in a new ordinal measure capturing the two-sided and multifaceted nature of conflict. Second,...

We investigate the empirical impact of violence as compared to other trade impediments on trade flows. Our analysis is based on a panel data set with annual observations on 177 countries from 1968 to 1999, which brings together information from the Rose [2004] dataset, the ITERATE dataset for...

This research establishes that the emergence, prevalence, recurrence, and severity of intrastate conflicts in the modern era reflect the long shadow of prehistory. Exploiting variations across national populations, it demonstrates that genetic diversity, as determined predominantly during the...

We examine how fiscal rules influence economic growth. The results show that constitutional fiscal rules promoted growth from the Industrial Revolution until World War II (1789-1950) and also increased modern economic growth (1985-2015). To address selection on unobservables, we conduct a...

We provide evidence that political instability deteriorates economic growth. We establish this result based on panel difference-in-differences strategies and dynamic panel data models using a large sample of 180 countries, a novel geocoded dataset for 2,660 regions, and micro data for about...

This paper proposes a simple framework to better understand an opposition group's choice between peace, terrorism, and open civil conflict against the government. Our model implies that terrorism emerges if constraints on the ruling executive group are intermediate and rents are sizeable, hereas...

This research advances the hypothesis and establishes empirically that interpersonal population diversity has contributed significantly to the emergence, prevalence, recurrence, and severity of intrasocietal conflicts. Exploiting an exogenous source of variations in population diversity across...

We use the synthetic control method to estimate the effect of international banking and energy sanctions from 2012 to 2015 on military spending of Iran. We create a synthetic control group that mimics the socioeconomic characteristics of Iran before the international sanctions of 2012. We then...
