Although the concept of reference point dependent preferences has been adopted to almost all fields of behavioral economics, especially marketing and behavioral finance, we still know very little about how decision makers form their reference points given a sequence of prices. Our paper provides...

Reference-dependent preferences have been well accepted in decision sciences, experimental economics, behavioral finance, and marketing. However, we still know very little about how decision makers form and update their reference points given a sequence of information. Our paper provides some...

We perform a market experiment to investigate how average transaction prices react to the arrival of new information. Following a positive shock in fundamental value, prices underreact strongly; following negative shocks we find evidence of a much less pronounced underreaction. After the shock,...

We analyze two recently documented follow-on purchase and repurchase patterns experimentally: Individual investors’ preference for purchasing additional shares of a stock that decreased rather than increased in value succeeding an initial purchase (pattern 1) and investors’ tendency for...

The disposition effect describes investors’ common tendency of quitting a winning investment too soon and holding on to losing investments too long (Shefrin and Statman 1985). Our paper analyses individual level disposition effects using both account level field data as well as a controlled...

We approach the problem of preference aggregation by endowing both individuals and coalitions with partially-ordered or incomplete preferences for decision under risk. Restricting attention to the case of complete individual preferences, and assuming complete preferences for some pairs of agents...

Probability and time are integral dimensions of virtually any decision. To treat them together, we consider the prospect of receiving outcome <i>x</i> with a probability <i>p</i> at time <i>t</i>. We define risk and time distance, and show that if these two distances are traded off linearly, then preferences are...

Why do we believe that more money will buy us more happiness (when in fact it does not)? In this paper, we propose a model to explain this puzzle. The model incorporates both adaptation and social comparison. A rational person who fully accounts for the dynamics of these factors would indeed buy...

Using a survey study of 261 decisions under uncertainty, we explore the factors that explain risk taking behavior and those that predict the importance of a decision. We also examine the relationship between framing and status quo, the similarity between monetary and non-monetary decisions, as...

We introduce a modification of the discounted utility model that accounts for both habituation and satiation in intertemporal choice. Habituation level and satiation level are state variables that induce changes in preferences as those states vary. We examine several properties of our model,...
