6. For the math mavens out there, the circle is a special case in which each dimension is of equal importance to the player. If one dimension is more important than the other, then we should draw an ellipse, each of whose radii reflects the relative importance of the issues. I skip this complicating detail here.
7. Those mathematically inclined and interested in delving more deeply into how it is possible for rational decision makers to move from any policy combination to any other, see Richard McKelvey, “Intransitivities in Multidimensional Voting Models and Some Implications for Agenda Control,” Journal of Economic Theory 12 (1976): 472-82; Richard McKelvey, “General Conditions for Global Intransitivities in Formal Voting Models,” Econometrica 47 (1979): 1085-1112; and Norman Schofield, “Instability of Simple Dynamic Games,” Review of Economic Studies 45 (1978): 575-94.
8. For a careful study of steroid use that is broadly consistent with the values used in this example, see Jenny Jakobsson Schulze, Jonas Lundmark, Mats Garle, Ilona Skílvíng. Lena Ekström, and Anders Rane, “Doping Test Results Dependent on Genotype of Uridine Diphospho-Glucuronosyl Transferase 2B17, the Major Enzyme for Testosterone Glucuronidation,” Journal of Clinical Endocrinology & Metabolism 93, no. 7 (July 2008): 2500-2506. Based on the values in this study, about 9 percent of a random sample from the population would falsely test positive. I assume 10 percent.
9. Bayes’ Theorem allows us to answer the question “What is the probability a person is of a particular type (such as a performance enhancing steroid user) given that they say or do something in particular (such as test positive for steroids)?” To answer this question we must solve the following calculation: Let P stand for probability, R for being a steroid user, S for testing positive, and ˜R for being the type of baseball player who does not use steroids. The straight line symbol | is read as “given.” Then P(R | S) =
Chapter 3: Game Theory 102
1. The first major efforts to show that arms races lead to war are the work of Lewis Fry Richardson, a distinguished meteorologist who predicted World War I but, using the same logic, failed to anticipate World War II. See his Arms and Insecurity (Chicago: Quadrangle, 1960). The literature tying arms races to war is vast but almost universally fails to consider that arms purchases are anticipatory, or, in game-theory lingo, they are endogenous, strategic decisions.
2. The subject of renegotiation-proofness has attracted the interest of many economists, leading to a vast literature. Some seminal papers include Dilip Abreu, David Pearce, and Ennio Stacchetti, “Renegotiation and Symmetry in Repeated Games,” Journal of Economic Theory 60, no. 2 (1993): 217-40; Jean-Pierre Benoit and Vijay Krishna, “Renegotiation in Finitely Repeated Games,” Econometrica 61 (1993): 303-23; and James Bergin and W. Bentley MacLeod, “Efficiency and Renegotiation in Repeated Games,” Journal of Economic Theory 61, no. 1 (1993): 42-73.
3. The seminal work on this question dates back to the eighteenth-century French philosopher, mathematician, and nobleman the Marquis de Condorcet. Regrettably, the latter characteristic—he opposed beheading the king and queen—cost him his life during the French Revolution. There is a wonderful statue of him on the left bank of the Seine, not too far from Notre Dame. I always pay homage to him when I am in Paris. His insights were built upon in the second half of the twentieth century to establish the modern understanding of voting methods. See, for instance, Kenneth Arrow, Social Choice and Individual Values (New York: John Wiley and Sons, 1951); William H. Riker, Liberalism Against Populism (New York: Freeman, 1982); Richard D. McKelvey and Norman Schofield, “Structural Instability of the Core,” Journal of Mathematical Economics 15, no. 3 (June 1986): 179-98; and Gary W. Cox, Making Votes Count (New York: Cambridge University Press, 1997).

See Duncan Black, The Theory of Committees and Elections (Cambridge: Cambridge University Press, 1958), and Anthony Downs, An Economic Theory of Democracy (New York: Harper, 1957).
