Step by step solution

01

Analysis of marginal benefit and marginal cost

Marginal benefit and marginal cost are compared to reach the optimal point of production. If the marginal benefit exceeds the marginal cost, the producer tends to increase the number of units produced. If the marginal cost exceeds the marginal benefit, the producer tends to decrease the number of units produced.

02

Explanation for part (a)

At 3,000 units, the value of the marginal cost (MC) is $10, and the value of the marginal benefit (MB) is $13. Here, the value of the MB is greater than the value of the MC. Hence, the producer should produce more units.

03

Explanation for part (b)

At 11 units, the value of the marginal cost (MC) is $4, and the value of the marginal benefit (MB) is $3. Here, the value of the MC is greater than the value of the MB. Thus, the producer should produce fewer units.

04

Explanation for part (c)

At 43,277 units, the value of the marginal cost (MC) is $99, and the value of the marginal benefit (MB) is $99. Here, the value of the MB is equal to the value of the MC. Hence, the producer should produce the current number of units.

05

Explanation for part (d)

At 82 units, the marginal cost (MC) is less than the marginal benefit (MB). As the marginal benefit is greater than the marginal cost, the producer should produce more units.

06

Explanation for part (e)

At 5 units, the marginal benefit (MB) is less than the marginal cost (MC). As the marginal cost is greater than the marginal benefit, the producer should produce fewer units.

Because investment and capital goods are paid for with savings, higher savings rates reflect a decision to consume fewer goods in the present to invest in more goods for the future. Households in China save 40 percent of their annual incomes each year, whereas U.S. households save less than 5 percent. At the same time, production possibilities are growing at roughly 7 percent per year in China but only about 3.0 percent per year in the United States. Use graphical analysis of ‘present goods’ versus ‘future goods’ to explain the difference between China's growth rate and the U.S. growth rate.

Suppose you won \(15 on a lotto ticket at the local 7-Eleven and decided to spend all the winnings on candy bars and bags of peanuts. Candy bars cost \)0.75 each, while bags of peanuts cost \(1.50 each.

  1. Construct a table showing the alternative combinations of the two products that are available.
  2. Plot the data in your table as a budget line in a graph. What is the slope of the budget line? What is the opportunity cost of one more candy bar? What is the opportunity cost of one more bag of peanuts? Do these opportunity costs rise, fall, or remain constant as additional units are purchased?
  3. Does the budget line tell you which of the available combinations of candy bars and bags of peanuts to buy?
  4. Suppose thatyou had won \)30 on your ticketnot \(15. Show the \)30 budget line in your diagram. Has the number of available combinations increased or decreased?

Potatoes cost Janice \(1 per pound, and she has \)5.00 that she could possibly spend on potatoes or other items. If she feels that the first pound of potatoes is worth \(1.50, the second pound is worth \)1.14, the third pound is worth \(1.05, and all subsequent pounds are worth \)0.30 per pound, how many pounds of potatoes will she purchase? How many pounds will she purchase if she has only $2 to spend?

What is an opportunity cost? How does the idea relate to the definition of economics? Which of the following decisions would entail the greater opportunity cost: allocating a square block in the heart of New York City for a surface parking lot or allocating a square block at the edge of a typical suburb for such a lot? Explain.
