Exercise 9.5 Another mechanism for the house allocation problem, familiar from the assignment of dorm rooms to college students, is the random serial dictatorship .5 Random Serial Dictatorship initialize H to the set of all houses randomly order the agents for i=1,2,3,...,n do assign the ith agent her favorite house h from among those in H delete h from H (a) Does an analog of Theorem 9.7 hold for the random serial dic- tatorship, no matter which random ordering is chosen by the mechanism? (b) Does an analog of Theorem 9.8 hold for the random serial dic- tatorship, no matter which random ordering is chosen by the mechanism
