Coupon value quantification program, recording medium, coupon value quantification method, and coupon value quantification device

摘要

PROBLEM TO BE SOLVED: To accurately and easily quantify the value of a coupon which is applied to a transaction in a predetermined product or service and grants the right to conclude a transaction at a reduced price when presented. A coupon value quantification program causes a computer to output a coupon value amount C (i) as a value obtained by quantifying the value of a coupon. The coupon value quantification program corresponds to at least the first variable S (i) corresponding to the degree of reduction, the second variable t corresponding to the remaining right period, which is the period from the present time to the expiration date, and the frequency of transactions. The coupon value amount C (i) is determined based on the third variable σ and the function C. The function C is similar to the binomial model constructed based on financial engineering, and the relationship between each variable S, t, σ and the coupon value amount C (i) is defined. This makes it possible to accurately and easily quantify the value of the coupon. [Selection diagram] Fig. 6
