List of some errata in book Games and Decision Making by Aliprantis & Chakrabarti page 30. (a) If u'(w^*) = 0 in the interior of an interval with u"(w) > 0, then the maximum is at one of the end points. Thus a risk seeking utility tends to pick end points. (b) If u"(w) < 0, then the maximum is at w^*. Thus a risk averse person, tends to pick a blend of choices. page 55: The condition is that A > c_1 + c_2 then we know the two firms can find a Nash equilibrium (in example 2.10). The region is between the lines q^*_1 = 0 and q^*_2=0, c_2 = 2c_1 - A, and c_2 = A/2 + c_1/2. pages 80-3 Section 3.2: Backward induction works whenever there is "no cycles". Of course it has to be correctly understood how to proceed when the graph is not a tree. Maybe some comment like this could be made. page 125, Ex 4a: This problem is wrong since 60-m > 40. Perhaps you mean monitor rather than "don't monitor". 4b. This should probably be h rather than F. page 125, line 7: If 72 + L >= H, then 0 <= w_2^* <= (91-H)/8 ... page 133: Beliefs are used to determine the expected payout from an information set. This is the reason we need to introduce the idea of beliefs. page 142: There is some confusion in example 5.6 whether the node is N or E. I think E should be replaced by N on the last two lines of page 142. p 147 Step III: The factor of 1/2 should be dropped. p 191 Defn: The d_i should be identified as the disagreement values. p207 Monotonicity: It should be s in s(B_T) and s' in s(B) rather than T and S. p 208 Figure 7.8: (1,4) is not the Nash point: (2,2.67) is. p 212 Example 7.12: D^* =0 and Profit = R - LW^* p 220 Figure 7.14: The dotted line should be inside the shaded area to illustrate the concept. p 227 n!: I think some dots were left out of the definition of n! p 242 line 22: Player's payoff here is larger than (delta_1 x) which is larger than (delta_1^2 x), as ... p 247 lines 6 & 8: x_h should have a delta_h in the numerator and x_l should have a delta_l since theorem 7.30 has a delta_2 in the numerator. This means that many inequalities have to be rewritten on pages 247-9. In particular, the first case of the theorem should be s^* =1 - delta_el(1-delta_1 x_el) if p_h delta_1^2 x_h + (1-p_h)(1 - x_el) > x_h.
