In the 40’s and early 50’ two decision theories were proposed and have since dominated the sceneof the fascinating field of decision-making. In 1944 – when von Neumann and Morgenstern showedthat if preferences are consistent with a set of axioms then it is possible to represent these...

In experimental economics there exists a lively debate about the independenceof observations. Although opinions on the issue dier widely, allconcerns regard the independence of subjects' behavior within one sessionor experiment. This paper attempts to shed some light on the independenceof...

Most research in economics models agents somehow motivated by out-comes. Here, we model agents motivated by procedures instead, whereprocedures are dened independently of an outcome. To that end, wedesign procedures which yield the same expected outcomes or carry thesame information on other's...

This paper studies a model of reference-dependent choice from sets of options grouped into categories. The proposed model is consistent with experimental evidence documenting context effects in a variety of choice situations. In our model, the reference point for any given category is...

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...

Evidence increasingly points to the importance of reference-dependence in predicting consumer behavior. We utilize detailed data from penny auctions, which first appeared as an internet phenomenon in the late 2000's, to uncover how consumers' prior experiences predict their willingness to try a...

We investigate the overall impact of stock-out on individual consumers' information search behavior through both search-theoretic and experimental approaches. As the probability of stock-out increases, search intensity decreases, while the expected number of searches may increase. Such increases...
