The beta-delta discounting model With beta-delta discounting,a discounting function can be specified by two parameters,B and 8,where o ≤B≤1and0<δ≤1. Overall utility is the sum of instantaneous utility from period o and is given by the following equation: Uoverall=Uo+B [8U1 +82U2+..] where: B is the present bias parameter that discounts utility in all non-current periods,and 6 is the discount rate parameter that discounts utility incrementally more in each subsequent period.
