Unit III Price Ceilings and Floors (Chapter 5)

1. Unit III Price Ceilings and Floors (Chapter 5)

2. In this chapter, look for the answers to these questions: • What are price ceilings and price floors? What are some examples of each? • How do price ceilings and price floors affect market outcomes? • How do taxes affect market outcomes? How does the outcome depend on whether the tax is imposed on buyers or sellers? • What is the incidence of a tax? What determines the incidence?

3. Market Disruptions • How do we ration goods and services? • Prices • Queues • Lotteries • Prices ration available resources most efficiently

4. Market Disruptions • When a drought occurs in the United States, what is the best means of rationing water? • California vs. Puerto Rico

5. Market Disruptions • When a drought occurs in the United States, what is the best means of rationing water? • California vs. Puerto Rico

6. Government Policies That Alter the Private Market Outcome • Price controls • Price ceiling: a legal maximum on the price of a good or service. Example: rent control. • Price floor: a legal minimum on the price of a good or service. Example: minimum wage. We will use the supply/demand model to see how each policy affects the market outcome (the price buyers pay, the price sellers receive, and eq’m quantity).

9. Black Markets • Market for illegal g/s • Market in which g/s trade at prices above their legal maximum prices • Tickets to sporting events • Rent in some cities • Stacia Bekemeyer

10. What do you think the housing market might look like in Amsterdam?

11. Questions 1. Why do we call a price that is lower than the equilibrium a price ceiling? 2. What would be the long-run effects of a price ceilingpolicy? 3. Isn’t it true that lower prices are a good thing for consumers?

12. Rent Control • placement of price ceilings on rents in particular cities • Over 200 American cities operate under some kind of rent control • Example: • New York City, Santa Monica, CA, Berkeley, CA

13. Two Functions of Rental Prices 1) promote efficient maintenance of existing housing / stimulate construction of new housing • Rent controls discourage the construction of new rental units. Why? • Rent -- most important long-term determinant of profitability / rent controls artificially depress them • Examples: • Dallas, Texas (16% vacancy) no rent control built 11,000 new rental units. • San Francisco (1.6 % vacancy) with rent control built 2000 new rental units

14. Two Functions of Rental Prices 2) allocate existing scarce housing among competing claimants • What happens to the current supply of housing? • When rental rates are held below the market equilibrium levels, property owners cannot recover the cost of maintenance, repairs, and capital improvements through higher rents. • In extreme situations, fixed costs exceed the rental returns. The result is abandoned buildings • Example: New York City and its numerous abandoned buildings.

15. Rent Control • Who loses in rent control? • landlords • low income individuals looking for first apartment • Who gains in rent control? • Upper-income professionals • Important: Effective rent controls discourage new rental unit construction, decrease spending on existing rental units and leads to a “Housing gridlock”

16. P S Rental price of apts $800 D Q 300 Quantity of apartments EXAMPLE 1: The Market for Apartments Eq’m w/o price controls

17. P S Price ceiling $1000 $800 D Q 300 How Price Ceilings Affect Market Outcomes A price ceiling above the eq’m price is not binding – it has no effect on the market outcome.

18. P S Price ceiling $500 shortage D Q 400 250 How Price Ceilings Affect Market Outcomes The eq’m price ($800) is above the ceiling and therefore illegal. The ceiling is a binding constrainton the price, and causes a shortage. $800

19. P S Price ceiling $500 shortage D Q How Price Ceilings Affect Market Outcomes In the long run, supply and demand are more price-elastic. So, the shortage is larger. $800 450 150

20. P S Price ceiling $500 shortage D Q Alternative Market Outcomes Alternative: Section 8 Grants $800 450 150

21. Shortages and Rationing • With a shortage, sellers must ration the goods among buyers. • Some rationing mechanisms: (1) long lines (2) discrimination according to sellers’ biases • These mechanisms are often unfair, and inefficient: the goods don’t necessarily go to the buyers who value them most highly. • In contrast, when prices are not controlled, the rationing mechanism is efficient (the goods go to the buyers that value them most highly) and impersonal (and thus fair???).

22. Price Floors in the Labor Market • Minimum Wage • wage floor, legislated by the government, setting the lowest hourly wage rate that firms may legally pay workers • Proponents: • ensure low-income workers a “decent”standard of living • Opponents: • causes increased unemployment • Note: Economists estimate that a 10% increase in the real minimum wage decreases total employment of those affected by 1 to 2%.

23. W S Wage paid to unskilled workers $4 D L 500 Quantity of unskilled workers EXAMPLE 2: The Market for Unskilled Labor Eq’m w/o price controls

24. W S Price floor $3 $4 D L 500 How Price Floors Affect Market Outcomes A price floor below the eq’m price is not binding – it has no effect on the market outcome.

25. labor surplus W S Price floor $5 $4 D L 400 550 How Price Floors Affect Market Outcomes The eq’m wage ($4) is below the floor and therefore illegal. The floor is a binding constrainton the wage, and causes a surplus (i.e.,unemployment).

26. unemp-loyment W S Min. wage $5 $4 D L 400 550 The Minimum Wage Min wage laws do not affect highly skilled workers. They do affect teen workers.

27. Earned Income Tax Credit • refundable tax credit primarily for individuals and couples with qualifying children • Theory -- Minimum wage laws are a undue burden on small business

28. Price Floors in Agriculture Historical note: 1933 Federal government placed price floors on agriculture • How it works: 1. Government sets a support price for ag product / acts to ensure that price never falls below support price 2. excess quantity supplied or surplus is purchased by government • 3. program run on a per bushel basis / larger farms better off • Note: 1996 these supports were supposed to be eliminated except for tobacco and peanuts

29. surplus P S Ag. Surplus $5 $4 D Q 400 550 Ag Price Floor Ag. Price supports create surplus Ag product in the market.

30. The market for hotel rooms P S D 0 Q ACTIVE LEARNING 1: Price floors & ceilings Determine effects of: A. $90 price ceiling B. $90 price floor C. $120 price floor 29

31. The market for hotel rooms P S Price ceiling D shortage = 30 0 Q ACTIVE LEARNING 1: A. $90 price ceiling The price falls to $90. Buyers demand 120 rooms, sellers supply 90, leaving a shortage. 30

32. The market for hotel rooms P S D 0 Q ACTIVE LEARNING 1: B. $90 price floor Eq’m price is above the floor, so floor is not binding. P = $100, Q = 100 rooms. Price floor 31

33. The market for hotel rooms P S surplus = 60 Price floor D 0 Q ACTIVE LEARNING 1: C. $120 price floor The price rises to $120. Buyers demand 60 rooms, sellers supply 120, causing a surplus. 32

34. Evaluating Price Controls • Markets are usually a good way to organize economic activity. • Prices are the signals that guide the allocation of society’s resources. This allocation is altered when policymakers restrict prices. • Price controls are often intended to help the poor, but they often hurt more than help them: • The min. wage can cause job losses. • Rent control can reduce the quantity and quality of affordable housing.

35. CHAPTER SUMMARY • A price ceiling is a legal maximum on the price of a good. An example is rent control. If the price ceiling is below the eq’m price, it is binding and causes a shortage. • A price floor is a legal minimum on the price of a good. An example is the minimum wage. If the price floor is above the eq’m price, it is binding and causes a surplus. The labor surplus caused by the minimum wage is unemployment.
