Working Paper
Measuring Geopolitical Risk
We present a news-based measure of adverse geopolitical events and associated risks. The geopolitical risk (GPR) index spikes around the two world wars, at the beginning of the Korean War, during the Cuban Missile Crisis, and after 9/11. Higher geopolitical risk foreshadows lower investment and employment and is associated with higher disaster probability and larger downside risks. The adverse consequences of the GPR index are driven by both the threat and the realization of adverse geopolitical events. We complement our aggregate measures with industry- and firm-level indicators of ...
Working Paper
Trade and Terrorism: A Disaggregated Approach
This paper constructs a model of trade consequences of terrorism, where firms in trading nations face different costs arising from domestic and transnational terrorism. Using dyadic dataset in a gravity model, we test terrorism?s effects on overall trade, exports, and imports, while allowing for disaggregation by primary commodities and manufacturing goods. While terrorism has little or no influence on trade of primary products, terrorism reduces trade of manufactured goods. This novel finding pinpoints the avenue by which terrorism harms trade and suggests why previous studies that looked at ...
Working Paper
A Theoretical Treatment of Foreign Fighters and Terrorism
The paper offers a game-theoretical model that includes three participants – the terrorist organization, its foreign fighters, and the adversarial host government. In stage 1, the terrorist group induces foreign fighters to emigrate through wage incentives, while the host government deters these fighters through proactive border security. Foreign fighters decide whether to emigrate from their source country (extensive margin) in stage 2, after which these fighters determine their level of attacks (intensive margin) in stage 3. Comparative statics to the Nash equilibrium are tied to changes ...
Working Paper
Immigration from a terror-prone nation: destination nation’s optimal immigration and counterterrorism policies
The paper presents a two-country model in which a destination country chooses its immigration quota and proactive counterterrorism actions in response to immigration from a terror-plagued source country. After the destination country fixes its two policies, immigrants decide between supplying labor or conducting terrorist attacks, which helps determine equilibrium labor supply and wages. The analysis accounts for the marginal disutility of lost rights/freedoms stemming from stricter counterterror measures as well the inherent radicalization of migrants. Comparative statics involve changes to ...
Working Paper
Terms-of-Trade and Counterterrorism Externalities
This paper investigates the interplay of trade and terrorism externalities under free trade between a developed nation that exports a manufactured good to and imports a primary product from a developing nation. A terrorist organization targets both nations and reduces its attacks in response to a nation?s defensive counterterrorism efforts, while transferring some of its attacks abroad. Terms-of-trade considerations lead the developed nation to raise its counterterrorism level beyond the ?small-country? level, thus compounding its over provision of these measures. By contrast, the developing ...
Working Paper
Financial market reactions to the Russian invasion of Ukraine
This article analyzes financial market reactions to the Russia-Ukraine war with a focus on the opening weeks. Markets did not completely anticipate the war and asset price reactions strengthened from the first week—when there were hopes for a quick resolution—to the second week, when prices generally peaked and began to partially revert to pre-war values. Exposure to commodity trade and trade with Russia-Ukraine determined market perceptions of the riskiness of equity and foreign exchange assets. Credit default swap prices on sovereign debt and breakeven inflation rates indicate that ...
Journal Article
The Trade-Offs of Counterterrorism Policies
This article provides a modern overview of counterterrorism tools and their trade-offs for curbing terrorist attacks and their consequences. Defensive and proactive countermeasures constitute two main classes of counterterror tools deployed by targeted governments. The primary drawback of defensive actions, which make terrorist attacks more costly and less apt to succeed, is attack transference that shifts the mode, venue, or target of attacks to those less protected. In contrast, offensive proactive measures, which confront the terrorists directly, may result in backlash as terrorist ...

Un-Fortunate Sons: Effects of the Vietnam Draft Lottery on the Next Generation's Labor Market
Can shocks to one generation propagate to the next? To answer this question, we study how the Vietnam draft lottery affected the next generation's labor market. Using the universe of federal tax returns, we link fathers from draft cohorts to their sons' outcomes and find that sons of fathers randomly called by the draft 1) have lower earnings and labor force participation than their peers, and 2) are more likely to volunteer for military service. These findings highlight the strong role family plays in human capital development and occupational choice. More generally, our results provide ...
Working Paper
Fiscal Stimulus and Consumer Debt
In the aftermath of consumer debt-induced recession, policymakers have questioned whether fiscal stimulus is effective during the periods of high consumer indebtedness. This study empirically investigates this question. Using detailed data on Department of Defense spending for the 2006-2009 period, we document that the open-economy relative fiscal multiplier is higher in geographies with higher consumer indebtedness. The results suggest that fiscal policy can mitigate the adverse effect of consumer (over)leverage on real economic output during a recession. We then exploit detailed microdata ...
Working Paper
On the Economic Mechanics of Warfare
The literature on war deals with finances, causes, or consequences. But, how do war-related expenditures affect economically-relevant outcomes at a war’s conclusion (e.g., prevailing side, duration, and casualties)? I present a model of attrition and characterize the effects of GDP at a military conclusion (one side cannot fight anymore) and a political conclusion (one side quits). The estimated model fits the data for the battle of Iwo Jima well. Analyzing data for the current Russo-Ukrainian war through the lenses of the model suggests that additional support to Ukraine could yield a ...
