Shortfall aversion reflects the higher utility loss of spending cuts from a reference than the utility gain from similar spending increases. Inspired by Prospect Theory's loss aversion and the peak-end rule, this paper posits a model of utility from spending scaled by past peak-spending. In...

Shortfall aversion reflects the higher utility loss of a spending cut from a reference point than the utility gain from a similar spending increase, in the spirit of Prospect Theory's loss aversion. This paper posits a model of utility of spending scaled by a function of past peak spending,...

Multivariate mixture models provide a convenient method of densityestimation and model based clustering as well as providing possible explanations for the actual data generationprocess. But the problem of choosing the number of components ($g$) in a statistically meaningful way is still asubject...
