Working Paper
Immigration policy and counterterrorism
A terrorist group, based in a developing (host) country, draws unskilled and skilled labor from the productive sector to conduct attacks at home and abroad. The host nation chooses proactive countermeasures, while accounting for the terrorist campaign. Moreover, a targeted developed nation decides its optimal mix of immigration quotas and defensive counterterrorism actions. Even though proactive measures in the host country may not curb terrorism at home, it may still be advantageous in terms of national income. Increases in the unskilled immigration quota augment terrorism against the ...

Poverty, political freedom, and the roots of terrorism in developing countries: An empirical assessment
This paper finds that political freedom has a significant and non-linear effect on domestic terrorism, but this effect is not significant in the case of transnational terrorism. Some of our other novel findings are that while geography and fractionalization may limit a county?s ability to curb terrorism, the presence of strong legal institutions deters it. ; Earlier title: "What spurs terrorism in developing nations?"

Terror Externalities and Trade: An Empirical Analysis
We report robust evidence of adverse cross-border externalities from terrorism on trade for over 160 countries from 1976 to 2014. Terrorism in one country spills over to reduce trade in neighboring nations. These externalities arise from higher trade costs due to trade delays and macroeconomic uncertainty.

Has September 11 affected New York City's growth potential?
In addition to exacting a tremendous human toll, the September 11 attack on the World Trade Center caused billions of dollars in property damage and a temporary contraction in New York City's economy. This article explores the effect of these events on the longer run economic prospects for the city. For many years, growth in New York has taken the form of rising property prices, reflecting a steady transition from low- to high-paying jobs. During the 1990s, the city's expansion was built on several factors, including improving fiscal conditions, better public services, and shifting industrial ...
Working Paper
Foreign aid as counterterrorism policy
We present a model where foreign aid bolsters proactive counterterrorism efforts of a foreign nation that is a source for transnational terrorism. Our two-stage game has the donor country choosing a first-stage contract consisting of terrorism-fighting tied aid and general assistance. In stage 2, the donor decides its defensive measures, while the recipient country chooses its proactive measures. An interesting finding is that the foreign enforcement best-response function is likely to reflect strategic substitutes, while the donor's enforcement best-response function is apt to indicate ...
Working Paper
Fiscal policy in the aftermath of 9/11
This paper investigates the nature of U.S. fiscal policy in the aftermath of 9/11. We argue that the recent dramatic fall in the government surplus and the large fall in tax rates cannot be accounted for by either the state of the U.S. economy as of 9/11 or as the typical response of fiscal policy to a large exogenous rise in military expenditures. Our evidence suggests that, had tax rates responded in the way they ?normally? do to large exogenous changes in government spending, aggregate output would have been lower and the surplus would not have changed by much. The unusually large fall in ...

The interplay between preemptive and defensive counterterrorism measures: a two-stage game
A two-stage game depiction of counterterrorism is presented, where the emphasis is on the interaction between the preemptive and defensive measures taken by two targeted countries facing a common threat. The preemptor is likely to be the high-cost defender with the greater foreign interests. A prime-target country may also assume the preemptor role. The analysis identifies key factors - cost comparisons, foreign interests, and targeting risks - that determine counterterrorism allocations. The study shows that the market failures associated with preemptive and defensive countermeasures may be ...
Working Paper
Effects of Neighboring Nation Terrorism on Imports
We present a monopolistic competition model to analyze the effects of own nation and neighboring nation terrorism on a nation’s imports. The theoretical analysis shows that own nation terrorism may leave relative price of imports unaffected, but neighboring nation terrorism must raise the relative price, reducing imports. We find that a 10% increase in terrorist attacks in a neighboring nation reduces a country’s imports from the rest of the world by approximately $320 million USD, on average. Mediation analysis shows that trading delays is a potential channel of transmission of trade ...
