The Interdependence Between Homeland Security Efforts of a State and a Terroristâ€™s Choice of Attack
Consider a state that chooses security levels at two sites (Targets A and B), after which a terrorist chooses which site to attack (and potentially a scope of attack). The state values A more highly. If the state knows which target the terrorist values more highly, he will choose a higher level of security at this site. Under complete information, if the terroristâ€™s only choice is which site to attack, the state will set security levels for which the terrorist prefers to attack A over B if and only if the ratio of the value of B to the value of A is greater for the state than for the terrorist. When the state has incomplete information on the terroristâ€™s target values, the optimal security levels may be such that: a target is completely undefended (but attacked with positive probability); the probability of attack is greater at A than at B; and the expected damage from an attack is greater at A than at B. In total, the results reveal that the stateâ€™s choice of security is heavily influenced by the terroristâ€™s target valuations.
