Satisficers (parte III)

"A solution to a given problem is called optimal if one can prove that no better solution exists. Some skeptics might ask, Why should intuition rely on a rule of thumb instead of the optimal strategy? To solve a problem by optimization—rather than by a rule of thumb—implies both that an optimal solution exists and that a strategy exists to find it. Computers would seem to be the ideal tool for finding the best solution to a problem. Yet paradoxically, the advent of high-speed computers has opened our eyes to the fact that the best strategy often cannot be found."

"Daniel Kahneman won the Nobel Prize in Economics because he demonstrated conclusively that people do not function according to the hyper-rational, cold calculating benefit maximizing cost minimizing Homo economicus that traditional economic theory presupposes."

"Decision makers often have imperfect information. We develop a choice theoretic experiment to explore choice mistakes that result from incomplete search. Our choice process methodology generates data on how choices change with contemplation time, thereby illuminating the search process. We demonstrate that most subjects behave in line with a reservation-based model of sequential search, altering their reservation utilities in response to the size of the choice set and the complexity of the environment. These …ndings support Simon’s model of satis…cing behavior and suggest simple measures of contextual e¤ects on the quality of decisions."
