Abstract
This paper analyzes the proposed use of combinatorial derivatives markets for event prediction, especially for catastrophic events such as terrorism, war, or political assasination. Following a presentation of the philosophical principles underlying these politico-economic tools, I examine case studies (U.S. DoD proposals) that evaluate their advantages and disadvantages in terms of both efficacy and moral considerations. I conclude that these markets are both fatally flawed due to internal conceptual contradictions and morally problematic.
