Consider firms that introduce new products, such as DVDs in 2001. When firms introduce new products, how do they typically determine the price elasticity of demand for those products? Firms with new products often A. guess price elasticity of demand based on market competition. B. identify price elasticity of demand by asking for government assistance. C. identify price elasticity of demand by using price controls to set price floors. D. estimate price elasticity of demand by experimenting with different prices. E. approximate price elasticity of demand with market signals such as surpluses.

Price elasticity of demand is an economic concept which is a measure of the sensitivity of customers willingness to buy something to its price. If the customers readily change their buying behavior with a change in price of the product, it would mean that the demand for the product is elastic.

When firms are introducing new products, they generally determine the best selling price by experimenting with different prices and observing the buying behavior of customers. Then the choose the price which produces the maximum amount of revenue for the firm, which entails the price of the product and number of units sold.
