The goal of this study is to ask whether investors learn differently from gains (positive news) versus losses (negative news), whether learning performance is better or worse when people are actively investing in a security or passively observing the security’s payoffs, and whether there are...

Following the development of advanced neuroimaging techniques, the growing interest in studying the brain’s response to marketing stimuli resulted in the birth of consumer neuroscience within the field of neuroeconomics. However, marketing scholars have remained reluctant to adopt the...

This study examines the systematic evidence entailed in existing research on consumers’ evaluation of biotechnology in food products. The extant literature related to this topic typically originates from a variety of research disciplines, but shares an underlying focus in dealing with the...

This volume contains eight papers written by Adam Brandenburger and his co-authors over a period of 25 years. These papers are part of a program to reconstruct game theory in order to make how players reason about a game a central feature of the theory. The program — now called epistemic game...

Sufficient conditions for Nash equilibrium in an n-person game are given in terms of what the players know and believe — about the game, and about each other's rationality, actions, knowledge, and beliefs. Mixed strategies are treated not as conscious randomizations, but as conjectures, on the...

Suppose that each player in a game is rational, each player thinks the other players are rational, and so on. Also, suppose that rationality is taken to incorporate an admissibility requirement — that is, the avoidance of weakly dominated strategies. Which strategies can be played? We provide...

Game-theoretic analysis often leads to consideration of an infinite hierarchy of beliefs for each player. Harsanyi suggested that such a hierarchy of beliefs could be summarized in a single entity, called the player's type. This chapter provides an elementary construction, complementary to the...

Best-response sets (Pearce [1984]) characterize the epistemic condition of “rationality and common belief of rationality.” When rationality incorporates a weak-dominance (admissibility) requirement, the self-admissible set (SAS) concept (Brandenburger, Friedenberg, and Keisler [2008])...

Two properties of preferences and representations for choice under uncertainty which play an important role in decision theory are: (i) admissibility, the requirement that weakly dominated actions should not be chosen; and (ii) the existence of well defined conditional probabilities, that is,...
