PROBLEM TO BE SOLVED: To determine an appropriate transaction price that brings about a necessary demand change without forcing a user to bear an excessive load.SOLUTION: The price determination device determines a transaction price in a transaction object for which a demand changes according to a price, and includes: a change prediction part for predicting a total demand change which is a total sum of the demand change for each user according to the price change based on a price elasticity model indicating the demand change according to the price change for each user; and a necessary price change calculation part for calculating the price change necessary for bringing about the necessary demand change based on a prediction result of the change prediction part. The price elasticity model has a border price of the price change and a limit value of the demand change for each user, and the more the price change increases, the more the demand change reduces or the more the price change reduces, the more the demand change increases until the demand change reaches the limit value from 0, and the demand change becomes constant at the limit value.
