description: Neuroeconomic conditions for “rational addiction” (Becker and Murphy, 1988) have  been unknown. This paper derived the conditions for “rational addiction” by utilizing a  nonlinear time-perception theory of “hyperbolic” discounting, which is mathematically  equivalent to the q-exponential intertemporal choice model based on Tsallis' statistics. It  is shown that (i) Arrow-Pratt measure for temporal cognition corresponds to the degree  of irrationality (i.e., Prelec’s “decreasing impatience” parameter of temporal  discounting) and (ii) rationality in addicts is controlled by a nondimensionalization  parameter of the logarithmic time-perception function. Furthermore, the present theory  illustrates the possibility that addictive drugs increase impulsivity via dopaminergic  neuroadaptation without increasing irrationality. Future directions in the application of  the model to studies in neuroeconomics are discussed.
