Testing a Rational Choice Model of airline hijackings
Criminology, 2005Co-Authors: Laura Dugan, Gary Lafree, Alex R PiqueroAbstract:Using data that combines information from the Federal Aviation Administration, the RAND Corporation and a newly developed database on global terrorist activity, we are able to examine trends in 1,101 attempted aerial hijackings that occurred around the world from 1931 to 2003. We have especially complete information for 828 hijackings that occurred before 1986. Using a Rational Choice theoretical framework, we use continuous-time survival analysis to estimate the impact of several major counterhijacking interventions on the hazard of differently motivated hijacking attempts and logistic regression analysis to Model the predictors of successful hijackings. Some of these interventions use certainty-based strategies of target hardening to reduce the perceived likelihood of success. Others focus on raising the perceived costs of hijacking by increasing the severity of punishment. We also assess which strategies were most effective in deterring hijackers whose major purpose was related to terrorism. We found support for the conclusion that new hijacking attempts were less likely to be undertaken when the certainty of apprehension was increased through metal detectors and law enforcement at passenger checkpoints. We also found that fewer hijackers attempted to divert airliners to Cuba once that country made it a crime to hijack flights. Our results support the contagion view that hijacking rates significantly increase after a series of hijackings closely clustered in time—but only when these attempts were successful. Finally, we found that the policy interventions examined here significantly decreased the likelihood of nonterrorist but not that of terrorist hijackings.

Testing a Rational Choice Model of airline hijackings
Lecture Notes in Computer Science, 2005Co-Authors: Laura Dugan, Gary Lafree, Alex R PiqueroAbstract:Using data that combines information from the Federal Aviation Administration, the RAND Corporation, and a newly developed database on global terrorist activity, we are able to examine trends in 1,101 attempted aerial hijackings that occurred around the world from 1931 to 2003. We have especially complete information for 828 hijackings that occurred before 1986. Using a Rational Choice theoretical framework, we employ econometric time-series methods to estimate the impact of several major counter hijacking interventions on the likelihood of differently motivated hijacking events and to Model the predictors of successful hijackings. Some of the interventions examined use certainty-based strategies of target hardening to reduce the perceived likelihood of success while others focus on raising the perceived costs of hijacking by increasing the severity of punishment. We also assess which specific intervention strategies were most effective for deterring hijackers whose major purpose was terrorism related. We found support for the conclusion that new hijacking attempts were less likely to be undertaken when the certainty of apprehension was increased through metal detectors and law enforcement at passenger checkpoints. We also found that fewer hijackers attempted to divert airliners to Cuba once that country made it a crime to hijack flights. Our results support the contagion view that hijacking rates significantly increase after a series of hijackings closely-clustered in time. Finally, we found that policy interventions only significantly decrease the likelihood of non-terrorist-related hijackings.

a Rational Choice Model of covid 19 transmission with endogenous quarantining and two sided prevention
Social Science Research Network, 2020Co-Authors: Joydeep Bhattacharya, Shankha ChakrabortyAbstract:This paper offers a parsimonious, Rational-Choice Model to study the effect of pre-existing inequalities on the transmission of COVID-19. Agents decide whether to “go out” (or self-quarantine) and, if so, whether to wear protection such as masks. Three elements distinguish the Model from existing work. First, non-symptomatic agents do not know if they are infected. Second, some of these agents unknowingly transmit infections. Third, we permit two-sided prevention via the use of non-pharmaceutical interventions: the probability of a person catching the virus from another depends on protection Choices made by each. We find that a mean-preserving increase in pre-existing income inequality unambiguously increases the equilibrium proportion of unprotected, socializing agents and may increase or decrease the proportion who self-quarantine. Strikingly, while higher pre-COVID inequality may or may not raise the overall risk of infection, it increases the risk of disease in social interactions.

a Rational Choice Model applied to private security companies military pscm un Modelo de decision racional aplicado a las companias militares de seguridad privada cmsp spanish
Social Science Research Network, 2010Co-Authors: Fernando EstradaAbstract:This paper aims to present a Rational decision Model applied to studies of private military security companies. These organizations complement the actions of the armed forces or (in some countries) take their place, they are fulfilling a delicate role on emerging democracies. Situations are illustrated in the case of Colombia.
