Austrian insights on the limits of central planning, the pervasiveness of knowledge problems, and the importance of the entrepreneur in coordinating social change have yielded substantive contributions to the literature on how individuals and communities respond to both natural and unnatural, or...

Population movements will help people facing the impact of climate change. However, the resulting large scale displacements may also produce security risks for receiving areas. The objective of this paper is to empirically estimate if the inflows of climate-induced migrants increase the risk of...

From time to time, the press reports the disruption of a terrorist plot by means of government agents infiltrating a terrorist network. Terrorists believe they are dealing with co-conspirators only to find they have been dealing with government agents. The problem facing the terrorists is an...

The purpose of this paper is to investigate the insights that might be generated into the nature of ‘lone wolf terrorism’ through the application of economic analysis. Orthodox approaches, particularly (standard) expected utility analysis and game theoretical analysis, are discussed. These...

Along with such factors as declining support, the dismantling of the leadership group and transition into legitimate political engagement there is another factor that is relevant to the decline and fall of terrorist groups. This is the group’s risk aversion. This aspect of the terrorist...

That terrorist organisations come and go is a fact. This empirical fact tends to draw attention to the demise of the terrorist organisation and distracts from the dynamics of the terrorist organisation’s life cycle. In this respect, the extant literature suffers from a serious weakness that is...

When a terrorist group's aspirations far exceed the outcomes that can be expected to result from any of the available attack methods, an outcome below the terrorist group's aspiration level is inevitable. A primary prediction of SP/A theory when applied to the study of terrorist behaviour is...

To design and apply effective countermeasures to hacking and related threats, it helps to have some way to structure one’s educated guesses and inferences about hackers’ current activities and future moves. This is especially the case when the decision-maker must consider not only the risk...

Homeland security against possible terrorist attacks involves making decisions under true uncertainty. Not only are we ignorant of the form, place, and time of potential terrorist attacks, we are also largely ignorant of the likelihood of these attacks. In this paper, we conceptualize homeland...

We use a dynamic stochastic general equilibrium model of integrated climate and economy (DSICE) to account for abrupt and irreversible climate change. We model a climate shock in the form of a stochastic tipping point. We investigate the impact of the tipping point externality on optimal...
