Transitivity is perhaps the most fundamental choice axiom and, therefore, almost all economic models assume that preferences are transitive. The empirical literature has regularly documented violations of transitivity, but these violations pose little problem as long as they are simply a result...

Preferences over risky alternatives can be elicited by different methods, including direct pairwise choices and willingness-to-accept valuations. The results are frequently at odds, casting doubts on the foundations of economics. We develop a stochastic choice model predicting when...

The random utility model (RUM, McFadden and Richter (1990)) has been the standard tool to describe the behavior of a population of decision makers. RUM assumes that decision makers behave as if they maximize a rational preference over a choice set. This assumption may fail when consideration of...

With complete information, choice of one option over another conveys preference. Yet when search is incomplete, this is not necessarily the case. It may instead reflect unawareness that a superior alternative was available. To separate these phenomena, we consider non-standard data on the...

This chapter examines how the original tenets of the affect-as-information hypothesis can be extended to explain a wide range of judgment phenomena, especially with respect to consumer decision making. To this end, research within social psychology as well as research from other fields such as...

I introduce a simple model of memory load in multiple attribute search and prove which types of search behavior require the least amount of memory load. The model is easily implementable and tracks choice error rates in the lab. The results on minimum memory load search can be used to explain a...

Multiple attribute search is a central feature of economic life: we consider much more than price when purchasing a home, and more than wage when choosing a job. Search behavior in these environments has recently been found to deviate systematically and substantially from optimal sequential...

A fundamental question is how firms adapt to environments that present multiple dimensions. Generally, the number of dimensions may exceed the limits of human attention. Subsequently, as organizations try to adapt to such environments they may be constrained to consider only a few dimensions. In...
