Bounded rationality and repeated network formation
نویسندگان
چکیده
We define a finite-horizon repeated network formation game with consent, and study the differences induced by different levels of individual rationality. We prove that perfectly rational players will remain unconnected at the equilibrium, while this result does not hold when, following Neyman (1985), players are assumed to behave as finite automata. We define two types of equilibria, namely the Repeated Nash Network (RNN), in which the same network forms at each period, and the Repeated Nash Equilibrium (RNE), in which different networks may form. We state a sufficient condition under which a given network may be implemented as a RNN. Then, we provide structural properties of RNE. For instance, players may form totally different networks at each period, or the networks within a given RNE may exhibit a total order relationship. Finally we investigate the question of efficiency for both Bentham and Pareto criteria.

Bounded Rationality in the Iterated Prisoner’s Dilemma
In diverse fields such as computer science, economics and psychology, bounded rationality has emerged as an important research topic. Models which assume the existence of perfectly rational agents seem inadequate for many realworld problems where agents often lack perfect rationality. Classes of imperfect rationality include the conditions of incomplete knowledge, memory, information or computa...
متن کاملBounded Rationality in Repeated Games∗
Models of bounded rationality often lead to sharper predictions about real world outcomes than their full rationality counterparts. Full rationality in repeated interactions allows a plethora of equilibrium outcomes. In this paper, I examine the effect of bounded rationality in infinitely repeated games. In particular, does the introduction of boundedly rational agents lead to a smaller set of ...
متن کاملB - 454 What is Bounded Rationality ? Paper prepared for the Dahlem Conference 1999
The paper deals with bounded rationality understood in the tradition of H.A. Simon. Fundamental problems and theoretical issues are discussed. Special emphasis is put on aspiration adaptation theory. Further remarks concern basic models of decision behavior (like learning and expectation formation), reasoning, and the connection between bounded rationality and motivation.
متن کاملHow bounded rationality can be optimal
A long-standing puzzle in economics and biology is why humans and animals sometimes exhibit “bounded rationality” by seeming not to adopt their optimal strategy when interacting with others 1–3. Many previous explanations involve repeated games, combined with mechanisms like reputation effects, punishment, “loners”, negotiation and genetic evolution. 1,4–6,6–13. Here we present a new kind of ex...
متن کاملRethinking Rationality
This chapter discusses the concept of bounded rationality as it is understood in the tradition of H.A. Simon. Fundamental problems and theoretical issues are presented, with special emphasis on aspiration adaptation theory. Further remarks concern basic modes of decision behavior (like learning and expectation formation), reasoning, and the connection between bounded rationality and motivation.
