Answer 4

Checks and credit cards are not money because they are not a means of payment. A check is an order to transfer a deposit from one person to another. The deposits are money but the checks are not. A credit card is an ID card that lets a person take out a loan at the instant he or she buys something. The loan still needs to be repaid with money so the credit card is not a means of payment, that is, it is not money.

Answer 5

The answer is often no. In a differentiated product market, the products offered by different firms are close but not perfect substitutes. In such a market, firms need to account for consumers' willingness to substitute among products. By reducing the price of its products or engaging in a price war, a firm may not be able to capture the entire market. Since the products are not exact substitutes, some consumers may continue to buy products sold by other firms at relatively higher prices.
