We present a dynamic two-country model in which military spending, geopolitical risk, and government bond prices are jointly determined. The model is consistent with three empirical facts: hegemons have a funding advantage, this advantage rises with geopolitical tensions, and war losers suffer...

The rise of civilizations involved the dual emergence of economies that could produce surplus ("prosperity") and states that could protect surplus ("security"). But the joint achievement of security and prosperity had to escape a paradox: prosperity attracts predation, and higher insecurity...

We develop a theoretical model of security investments in a network of interconnected agents. Network connections introduce the possibility of cascading failures due to an exogenous or endogenous attack depending on the profile of security investments by the agents. The general presumption in...

From 2000 to 2010, more than 20 states passed laws that make it easier to use lethal force in self-defense. Elements of these laws include removing the duty to retreat in places outside of one's home, adding a presumption of reasonable belief of imminent harm, and removing civil liability for...

As billions of people in the developing world seek to increase their living standards, their aspirations pose a challenge to global efforts to cut greenhouse gas emissions. The emerging middle class are buying and operating energy intensive durables ranging from vehicles to air conditioners to...

This paper applies principles of adverse selection to overcome obstacles that prevent the implementation of Pigouvian policies to internalize externalities. Focusing on negative externalities from production (such as pollution), we consider settings in which aggregate emissions are known, but...

We document the rise of China in offshore capital markets. Chinese firms use global tax havens to access foreign capital both in equity and bond markets. In the last twenty years, China's presence went from raising a negligible amount of capital in these markets to accounting for more than half...

We study how international agreements can take advantage of domestic time-inconsistency problems in the context of environmental policies. For example, policymakers will prefer future policies to be sustainable, but find it tempting to raise consumption when being in office. We find the...

This paper studies the long-run effects of government-led construction of manufacturing plants on the regions where they were built and on individuals from those regions. Specifically, we examine publicly financed plants built in dispersed locations outside of major urban centers for security...

There has been a revival of warfare and threats of interstate war in recent years as the number of countries engaged in armed conflict surged dramatically, reaching to levels unprecedented since the end of Cold War. This is happening at a time when the global burden of mental health illness is...
