A new system of analyzing advertising revenue derivation is provided that
is particularly useful for predicting an amount of revenue that can be
expected from advertisements placed in a business directory book having a
certain geographic coverage. The system comprises estimating a preference
factor of advertisers located in a first geographic area of placing
advertisements in other geographic areas. This preference factor, along
with other demographic data, is used to calculate a choice probability
that advertisers will choose to place an advertisement in one business
directory book over other competing books. A total amount of expected
revenue for each particular geographic area within a metropolitan area is
calculated. Finally, the total amount of expected revenue attributable to
a particular business directory book is predicted based on the choice
probability and the total amount of expected revenue for each geographic
area.
