Assume the total utilities corresponding to the first four units of a product consumed are 8, 12, 14, 15, respectively. The marginal utility of the third unit consumed is:

Exhibit 3-21 Demand and supply curves ​ ​ If the market supply increases and, simultaneously, market demand decreases, the new equilibrium will show:

Assume the price of Nikes decreases. As a result, consumers increase the quantity of Nikes purchased each year and purchase fewer Reeboks. This is an example of the:

Exhibit 7-16 Long-run average cost curves ​ ​ In Exhibit 7-16, which firm’s long-run average cost curve experiences constant returns to scale between 2 and 5 units?

Michael spends $10 a month on Pez dispensers and Superman action figures. His marginal-utility-to-price ratio for the Pez dispensers is 40, while his marginal-utility-to-price ratio for Superman action figures is 47. Explain why Michael is not maximizing his utility and how can he change his behavior to increase his utility?

People who enjoy the benefits of a public good without paying for them are called:

For a normal good, an increase in consumer income will cause the market demand for the product to:

Suppose that for Savion the marginal utility of $50-per-serving caviar is 100 and the marginal utility of $1-per-serving popcorn is 10. For his snack, Savion should buy:

Price ceilings set below the equilibrium create:

If total utility is falling, marginal utility is:
