Interdependent defense games with applications to Internet security at the level of autonomous systems

Chan, Hau; Ceyko, Michael; Ortiz, Luis - In: Games 8 (2017) 1, pp. 1-60

instances of IDD games based on the real-world Internet-derived graph at the level of autonomous systems (≈27 K nodes and ≈100 K … edges as measured in March 2010 by the DIMES project). We call such games Internet games. We introduce and empirically …-generated instances of Internet games. In general, preliminary experiments applying our proposed heuristics are promising. Our experiments …

Optimal voluntary vaccination of adults and adolescents can help eradicate Hepatitis B in China

Scheckelhoff, Kristen; Ejaz, Ayesha; Erovenko, Igor V.; … - In: Games 12 (2021) 4, pp. 1-13

Hepatitis B (HBV) is one of the most common infectious diseases, with a worldwide annual incidence of over 250 million people. About one-third of the cases are in China. While China made significant efforts to implement a nationwide HBV vaccination program for newborns, a significant number of...

A game-theoretic model of strategic interaction using advertising : simulating the evolution of the Cournot Nash equilibrium under different competitive scenarios

Brady, Malcolm - In: Games 12 (2021) 4, pp. 1-16

This paper examines the behaviour of two firms competing in a duopoly, where firms can influence demand through use of advertising. The paper simulates the strategic interaction of the two firms based on a game-theoretic Cournot analytical model. The evolution over time of the Nash equilibrium...

Governmental taxation of households choosing between a national currency and a cryptocurrency

Wang, Guizhou; Hausken, Kjell - In: Games 12 (2021) 2, pp. 1-24

A game between a representative household and a government was analyzed. The household chose which fractions of two currencies to hold, e.g., a national currency such as a Central Bank Digital Currency (CBDC) and a global currency such as Bitcoin or Facebook's Diem, and chose the tax evasion...

COVID-19 : data-driven mean-field-type game perspective

Tembine, Hamidou - In: Games 11 (2020) 4/51, pp. 1-107

In this article, a class of mean-field-type games with discrete-continuous state spaces is considered. We establish Bellman systems which provide sufficiency conditions for mean-field-type equilibria in state-and-mean-field-type feedback form. We then derive unnormalized master adjoint systems...

μ-σ games

Dulleck, Uwe; Löffler, Andreas - In: Games 12 (2021) 1/5, pp. 1-12

Risk aversion in game theory is usually modeled using expected utility, which was criticized early on, leading to an extensive literature on generalized expected utility. In this paper we are the first to apply μ-σ theory to the analysis of (static) games. μ-σ theory is widely accepted in...

Validating game-theoretic models of terrorism : insights from machine learning

Bang, James T.; Basuchoudhary, Atin; Mitra, Aniruddha - In: Games 12 (2021) 3, pp. 1-20

There are many competing game-theoretic analyses of terrorism. Most of these models suggest nonlinear relationships between terror attacks and some variable of interest. However, to date, there have been very few attempts to empirically sift between competing models of terrorism or identify...

Security investment, hacking, and information sharing between firms and between hackers

Hausken, Kjell - In: Games 8 (2017) 2, pp. 1-23

A four period game between two firms and two hackers is analyzed. The firms first defend and the hackers thereafter attack and share information. Each hacker seeks financial gain, beneficial information exchange, and reputation gain. The two hackers’ attacks and the firms’ defenses are...

The emotional moves of a rational actor : smiles, scowls, and other credible messages

Reed, Lawrence Ian; DeScioli, Peter - In: Games 8 (2017) 2, pp. 1-11

Many scholars turn to emotions to understand irrational behavior. We do the opposite: we turn to rationality and game theory to understand people’s emotions. We discuss a striking theory of emotions that began with the game theory of credible threats and promises, then was enriched by...

Game theory of pollution : national policies and their international effects

Schüller, Katharina; Staňková, Kateřina; Thuijsman, … - In: Games 8 (2017) 3, pp. 1-15

In this paper we put forward a simple game-theoretical model of pollution control, where each country is in control of its own pollution, while the environmental effects of policies do not stop at country borders. In our noncooperative differential game, countries as players minimize the present...
