ABSTRACT This paper employs advanced time series methods to identify the dynamic properties of three hostage taking series. The immediate and long run multipliers of three covariates--successful past negotiations, violent ends, and deaths--are identified. Each hostage series responds differently to the covariates. Past concessions have the strongest impact on generating future kidnapping events, supporting the conventional wisdom to abide by a stated no-concession policy. Each hostage series has different changepoints caused by a variety of circumstances. Skyjackings and kidnappings are negatively correlated, while skyjackings and other hostage events are positively correlated. Policy recommendations are offered.

    ABSTRACT: What factors drive the length of a kidnapping experience? A theoretical model is developed to conduct comparative statics. A unique data set covering all kidnappings for ransom in Sardinia between 1960 and 2010 is analyzed. Factors related to the ability to pay and cost of abduction matter. Policies aimed at deterring kidnapping have mixed effects on its duration.

    ABSTRACT: This article examines the power of interpersonal communication models and frameworks to help negotiators and counterterrorist teams reach successful outcomes during hostage negotiations. A fundamental premise is that superior communication with hostage takers, such as subtle linguistic techniques and other forms of discourse, is essential to obtain the liberation of hostages. An important theory is Mark Knapp's (1984) model of relational development, which postulates that relationships (e.g., between captors and captives) improve through constant interpersonal dialogue. The idea is that ongoing relationship development is indispensable at each stage of the hostage negotiation process. The ultimate objective is to establish rapport and move into the hostage takers’ world.

    ABSTRACT: This article investigates the determinants of terrorist groups' failure by applying survival analysis in a discrete-time specification. Our sample consists of a diverse set of 586 terrorist groups, in which just over 63% end operations (demise) during 1970-2007. We use RAND event data and Jones and Libicki terrorist group data. Findings show that the survival of terrorist groups is bolstered by diversifying attacks, having multiple home bases, locating in the Middle East, locating in a democratic country, and limiting reliance on transnational terrorist attacks. Moreover, larger groups have better survival prospects. Religious fundamentalist terrorist groups face better survival prospects than other terrorist groups. Terrorist groups located in a country with larger tropical territory are less likely to end operations; however, groups based in a landlocked country are more likely to fail.
