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. ...

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 ...

Terrorism, Trade, and Welfare
For a standard competitive trade model, the authors show that the incidence of terrorism in different nations can affect the pattern of trade. Nations with a greater incidence of terrorism will export goods that are more immune to terrorism-related disruptions, while importing more terrorism-impacted goods. In addition, terrorism can be welfare augmenting for some nations because of terms-of-trade externalities. Finally, the authors present some qualitative conditions that identify when a nation?s trade volume may rise (or fall) in response to a greater incidence of terrorism. Given the ...

Local and Aggregate Fiscal Policy Multipliers
In this paper, we estimate the effect of defense spending on the U.S. macroeconomy since World War II. First, we construct a new panel dataset of state-level federal defense contracts. Second, we sum observations across states and, using the resulting time series, estimate the aggregate effect of defense spending on national income and employment via instrumental variables. Third, we estimate local multipliers using the state-level data, which measures the relative effect on economic activity due to relative differences in defense spending across states. Comparing the aggregate and local ...

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 ...

On the Economic Mechanics of Warfare
A large literature is concerned with war finance, but there is little by way of understanding how war-related expenditures affect the economically-relevant outcomes of wars, e.g., prevailing side, duration, or destruction and casualties. I present a model of attrition in which I characterize the effects of resources on the outcomes of war for a military conclusion (when one side cannot fight anymore) and a political conclusion (when one side does not want to fight anymore). I discuss the role of GDP for both types of conclusion. I also analyze the mechanics of third-party support to a small ...

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
Voluntary participation in a terror group and counterterrorism policy
A three-stage game investigates how counterterrorism measures are affected by volunteers’ choice in joining a terrorist group. In stage 1, the government chooses both proactive and defensive countermeasures, while looking ahead to the anticipated size and actions of terrorist groups. After radicalized individuals choose whether to join a terrorist group in stage 2, group members then allocate their time between work and terrorist operations. Based on wages and government counterterrorism, the game characterizes the extensive margin determining group size and the intensive margin ...

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 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 ...
