Sion, Radu (ed.), Financial cryptography and data security. 14th international conference, FC 2010, Tenerife, Canary Islands, January 25‒28, 2010. Revised selected papers. Berlin: Springer (ISBN 978-3-642-14576-6/pbk). Lecture Notes in Computer Science 6052, 416-423 (2010).
Summary: This paper presents a formal, quantitative evaluation of the impact of bounded-rational security decision-making subject to limited information and externalities. We investigate a mixed economy of an individual rational expert and several naïve near-sighted agents. We further model three canonical types of negative externalities (weakest-link, best shot and total effort), and study the impact of two information regimes on the threat level agents are facing.
