<p>The present invention determines the prices of intangibles such as music data. An exposures computing system accesses Web servers via the Internet to detect the number of exposures of information about specified music data. A demand computing system accesses the Web servers via the Internet to search for the number of sales and the number of reservations of that music data and computes a demand on the basis of the retrieved information. On the basis of the obtained number of exposures and the obtained demand, a pricing index computing system computes a pricing index by which the price of the music data is determined. <IMAGE></p> |
