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 prewar values. Exposure to commodity trade and trade with Russia and 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 ...

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 ...

The Economic Effects of a Potential Armed Conflict Over Taiwan
This article examines the likely economic effects of a Chinese invasion or blockade of Taiwan for the U.S. and the world by considering historical precedents. Such a conflict would likely produce a flight-to-safety in the asset market, huge disruptions in international trade, and banking problems, and it would greatly exacerbate existing fiscal pressures. The authorities of the People’s Republic of China would probably try to sell U.S. and other western securities prior to a conflict to avoid sanctions on those assets. Such sales would be temporarily disruptive but would likely have only ...

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 ...

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 ...

Fiscal multipliers in advanced and developing countries: evidence from military spending
Using novel data on military spending for 129 countries in the period 1988?2013, this paper provides new evidence on the effects of government spending on output in advanced and developing countries. Identifying government-spending shocks with an exogenous variation in military spending, we estimate one-year fiscal multipliers in the range 0.75-0.85. The cumulative multipliers remain significantly different from zero within three years after the shock. We find substantial heterogeneity in the multipliers across groups of countries. We then explore three potential sources leading to ...

The effects of terrorism on trade: a factor supply approach
The conventional view of terrorism is that it raises risks and, as a result, reduces trade. The authors use a factor supply approach to show that this hypothesis is not necessarily correct. They use a two-good, two-factor, small open economy model to show that terrorism can either reduce or raise trade depending on critical factors, such as the impact of terrorism on the intensive factor of the export or the import sector. They then extend the analysis to models with several goods and factors and identify conditions under which trade may rise or fall with a greater incidence of terrorism. ...

Battles and Diseases in the U.S. Civil War
Wars create short-term fluctuations in mortality. Belligerents might mitigate their own casualties with larger armies that hinder their opponent’s fighting ability. But diseases are frequent in wars and, thus, may reduce the benefits of larger armies. First, I analyze these competing mechanisms in a dynamic model of wartime attrition. Second, I calibrate the model using U.S. Civil War data and find that if the Union had fielded a 50%-larger army in 1861, Union casualties would have been marginally lower. The theory provides the insight for this quantitative result.
