....detail in, among other places, 8] and [13] Mechanism design is a powerful tool that helps a principal (in this case, the utility) with no private information about its customers, decide in an optimal way how much to buy from (or sell to) its customers and at what price. The revelation principle [9, 5, 14] is used to simplify the problem. The mechanism (or contract offer structure) can be designed in a way that customers wishing to maximize their own total benefit are forced to reveal their true valuation of power interruptions. The mechanism has two kinds of output: a decision vector (amounts to ....

....Nash equilibria (or other notions of noncooperative behavior) rather than strategyproofness: That is, they assume that simultaneous selfish play leads to a self consistent equilibrium, called a Nash equilibrium, in which no agent can improve her lot by deviating. The Nash implementation approach [3, 19] involves designing resource allocation mechanisms with Nash equilibria that yield the socially desirable outcome (such as an e#cient and or budget balanced and or fair allocation) In contrast, strategyproofness ensures that no matter how other agents behave whether selfish, spiteful, or ....

....concepts introduced so far. In the next two sections we investigate the implications of monotonic closure of the domain, and of continuity of the social choice function. 3 Monotonic Closure We now consider the property of monotonic closure (MC) a concept originally called rich domain in Dasgupta Hammond Maskin (1979) and then rechristened in Maskin (1985) Definition 4 [Maskin] A domain of utility functions U is monotonically closed (MC) if, for all pairs U; V 2 U , and all pairs x; y 2 B such that (1) U(x) U(y) V (x) V (y) and (2) U(x) U(y) V (x) V (y) there exists some W 2 U such that for all ....
....can find another sequence U t of utility functions representing the same preferences such that lim t 1 U t (x) U(x) for all allocations x. The domains U c and U sc are monotonically closed, and in fact U sc is strictly monotonically closed. This can be seen by Example 3.1. 2 in Dasgupta Hammond Maskin (1979), where a similar result is established for continuous, strictly convex, strictly monotonic preferences. Note that our domains U c and U sc are also continuously closed. Lemma 2 U c and U sc are continuously closed. Proof: The following proof applies for both U = U c and U = U sc . ....
