A terrorist defends an asset which grows from the first to the second period and is attacked. With large asset growth, the terrorist's first period outcome is low caused by a large attack. With no expenditure constraint, the terrorist's total outcome is positive. With equal attack and defense...

The article proposes an enabling mechanism for the creation, adjustment and dissolution of governmental units, giving autonomy to each resident as in a direct democracy. Rather than focusing on a narrow model with restrictive and specialized assumptions, and subsequent solutions, as has been...

Joint exchange and raiding can emerge in a world of mutual raiding when the appropriated production is less valuable to the appropriator than to the defender and the defense is not too inferior to attack. The amounts of resources allocated to production and raiding and the amounts of goods...

A two-period exchange model is developed where production decisions in the first period determine the amount of resources available in the second period. Each agent allocates resources to defend its production and attack the production of the other agent. Production, conflict and exchange occur...

The ratio of within-group to between-group fighting is shown to be unrealistically high for the collective rent seeking model when agents exert two efforts i.e. within-group and between-group efforts. The ratio is more realistic for the production and conflict model. Six economics examples...

A company allocates a resource between safety effort and production. The government earns taxes on production. The disaster probability is modeled as a contest between the disaster magnitude and the two players’ safety efforts. The model illustrates that safety efforts are strategic...

A sequential Colonel Blotto and rent seeking game with fixed and variable resources is analyzed. With fixed resources, which is the assumption in Colonel Blotto games, we show for the common ratio form contest success function that the second mover is never deterred. This stands in contrast to...

A system of components can be in series, parallel, or combined series/parallel. The components and system are protected individually and overarchingly by a defender, and attacked individually and overarchingly by an attacker. Both layers of protection have to be breached for an attack to be...

The 2011 UK tax rise on hydrocarbon exploitation activities obviously increases short term tax revenues however the longer term effects are less clear. The strategic interaction between the UK government, a producer and a shipper has been analyzed in a game theoretical model. A complex...

Kovenock and Roberson's (2012a, b) replication of Hausken’s (2008a) equations and parameter restrictions do not enhance our insight into the defense and attack of reliability systems. This reply intends to fill the remaining understanding gaps.
