But have we indeed expanded the scope of economic models beyond the circumstances in which decision makers carry out explicit optimization? Consider the following “decision scheme,” named satisficing by Herbert Simon. Let v : X →± be a valuation of the elements in X , and let v ∈± be a threshold of satisfaction. Let O be an ordering of the alternatives in X . Given a set A , the decision maker arranges the elements of this set in a list L ( A , O ) according to the ordering O .He then chooses the first element in L ( A , O ) that has a v -value at least as large as v . If there is no such element in
