I derive indifference curves in mean-standard deviation space for investors with prospect theory preferences when returns are normally distributed. The normality assumption creates a mapping between model parameters and the investment opportunity set. The model is then calibrated to historical...

This paper analyzes infant mortality in a unique and highly-detailed data set from Uruguay.
