A demand set is a model of the most-preferred bundle of goods an agent can afford. The set is a function of the preference relation for this agent, the prices of goods, and the agent's endowment. Assuming the agent cannot have a negative quantity of any good, the demand set can be characterized this way: Define as the number of goods the agent might receive an allocation of. An allocation to the agent is an element of the space ; that is, the space of nonnegative real vectors of dimension . Define as a weak preference relation over goods; that is, states that the allocation vector is weakly preferred to . Let be a vector representing the quantities of the agent's endowment of each possible good, and be a vector of prices for those goods. Let denote the demand set. Then: D(>p,p,e) = {x: px <= pe and x >p x' for all affordable bundles x'. ==See also== *Demand *Economics 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Demand set」の詳細全文を読む スポンサード リンク
