Quantity demanded of toothpaste decreases, and the quantity of toothpaste that firms want to supply increases 4. Which of the following is the most likely explanation for the imposition of a price ceiling on the market for milk? Buyers of milk, recognizing that he price celling is good for them, have pressured policymakers into imposing the price celling 5. Which of the following is not an example of a public policy? Equilibrium laws 6. if the government wants to reduce the burning of fossil fuels, it should impose a tax on either buyers or sellers of petrol 7. In a competitive market free of government regulation, Price adjusts until quantity demanded equals quantity supplied

8. A tax burden falls more heavily on the side of the market that is less elastic. True 9. Which of the following is correct?

Suppose that the demand for digital cameras is elastic, and the supply of digital cameras is inelastic. A tax of $20 per camera levied on digital cameras will decrease the effective price received by sellers of digital cameras by Between $10 and $20 14. Which of the following is correct? Price controls Often hurt those they are designed to help

15. When a binding price ceiling is imposed on a market to benefit buyers, Some buyers benefit and some buyers are harmed 16. A binding price ceiling (i) causes a surplus. (ii) causes a shortage. (iii) is set at a price above the equilibrium price. (iv) is set at a price below the equilibrium price. (ii) and (iv) only 17. A tax on the buyers of cameras encourages Buyers to demand a smaller quantity at every price 18. If the demand curve is very inelastic and the supply curve is very elastic in a market, then the sellers will bear a greater burden of a tax imposed on the market, even if the tax is imposed on the buyers. 19. If a price celling is not binding, then The equlilbrium price is below the price celling

Week 4 1. When comparing short-run average total cost with long-run average total cost at a given level of output, Short-run average total cost is typically above long-run average total cost 2. Short run is a period of time In which a firm uses at least one fixed input 3. If the total variable cost of producing 5 units of output is $10 and the total variable cost of producing 6 units is $15, the marginal cost of producing the sixth unit is $5. True 4. Frank owns a dog-grooming business. Which of the following costs would be implicit costs?

Since the 1980s, Wal-Mart stores have appeared in almost every community in America. Wal-Mart buys its goods in large quantities and, therefore, at cheaper prices. Wal-Mart also locates its stores where land prices are low, usually outside of the community business district. Many customers shop at Wal-Mart because of low prices. Local retailers, like the neighborhood drug store, often go out of business because they lose customers. This story demonstrates that

There are economies of scale in retail sales 12. Which of the following explains why long-run average cost at first decreases as output increases? Gains from specialization of inputs 13. The marginal product of any input is the Increase in total output obtained from one additional unit of that output 14. The marginal-cost curve intersects the average-total-cost curve at the minimum point of the marginal-cost curve. False 15. Which of the following statements is not true MC=ATC/Q 16. If MC is less than ATC, we know that: ATC must be falling 17. Economists normally assume that the goal of a firm is to earn (i) profits as large as possible, even if it means reducing output. (ii) profits as large as possible, even if it means incurring a higher total cost. (iii) revenues as large as possible, even if it reduces profits. (ii) and (ii) only 18.

The kayak company exhibits constant returns to scale because average total cost is constant as output rises Week 5 1.
