The Logic of Maximizing Behavior and Maximizing in the Marketplace
Read these sections revisit the concept of marginal costs and benefits within the context of the consumer's (and the firm's) maximizing behavior. The later pages in this section define two new concepts: consumer surplus and producer surplus. Take a moment to read through the stated learning outcomes, which should be your goals as you read through the chapter. Attempt the "Try It" problem for each section.
The Logic of Maximizing Behavior
Heads Up
It is easy to make the mistake of assuming that if an activity is carried out up to the point where marginal benefit equals marginal cost, then net benefits must be zero. Remember that following the marginal decision rule and equating marginal benefits and costs maximizes net benefits. It makes the difference between total benefits and total cost as large as possible.
