Cooperation in providing common goods is crucial for flourishing social systems, yet rare but extreme events, such as pandemics, stock market collapses, and terror attacks, pose a risk that could undermine cooperation. We extend the public goods game (PGG) to investigate the relationship between...

Complex systems exposed to pollution may suddenly and permanently shift to a dangerous regime. This paper studies a dynamic game among countries that face the prospect of such a shift. Each country derives some flow utility from its own emissions, which are chosen unilaterally. But flow...

Climate change is one of the major global challenges. Mitigating its impact is however bedeviled byfree-rider problems and external effects. We thus study the problem of optimal carbon abatement in a dynamic non-cooperative game-theoretical setting involving multiple countries that are open...

The provision of global public goods, such as climate change mitigation and managing fisheries to avoid overharvesting, requires the coordination of national contributions. The contributions are managed by elected governments who, in turn, are subject to public pressure on the matter. In an...

In Rome, on 16 March 1978, the Red Brigades kidnapped Aldo Moro. They kept him a prisoner for 55 days, and ultimately killed him. Why did they decide to kill Moro since it appears a posteriori that they did not improve their situation by doing so? Our paper answers this question by building...

In our original comment, we showed that Hausken's characterization of Nash equilibrium is invalid for much of the parameter space examined and provided necessary conditions for his solution to hold. Most of the comments in his reply are either tangential or irrelevant. However, several of the...

Kovenock and Roberson’s (2012ab) 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.

Hausken (2008a) formulates a contest-theoretic model of the attack and defense of a network of targets. This note identies a technical error that invalidates Hausken's characterization of Nash equilibrium for a substantial portion of the parameter space that he examines and provides necessary...

Kovenock and Roberson’s (2010) paper has the potential to advance the research frontier, but has deficiencies. This paper suggests how Kovenock and Roberson’s (2010) paper can be developed into a more substantial paper. Kovenock and Roberson’s (2010) paper consists of three sections. The...
