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,...

Portfolio choice is usually modelled by von Neumann-Morgenstern utility. Risk-value models are more general and permit the derivation of risk-value efficient frontiers. A behaviourally based risk measure with an endogenous or exogenous benchmark is used to derive effcient portfolios and to...
