We develop a dual-self model of self-control that is compatible with
modern dynamic macroeconomic theory and evidence. We show that a convex cost of self-control explains a wide range of behavioral anomalies concerning risk, including the Allais paradox, and also
explains the observed interaction between risk and delay. We calibrate the model to obtain a quantitative fit. We find that most of the data can be explained with subjective interest rates in the range of 1-7 percent, short-run relative risk aversion of about two, and a time horizon of one day for the short-run self.
