It is common to apply multipliers to both earnings and book value to calculate approximate equity values. However, applying a price-earnings multiplier or a price-to-book multiplier typically produces two valuations and the analyst is left with the question of how to combine them into one valuation.

Bid-prices are becoming an increasingly popular method for controlling the sale of inventory in revenue management applications. In this form of control, threshold—or "bid"—prices are set for the resources or units of inventory (seats on flight legs, hotel rooms on specific dates, etc.) and a product (a seat in a fare class on an itinerary or room for a sequence of dates) is sold only if the offered fare exceeds the sum of the threshold prices of all the resources needed to supply the product.
