I. Housing Markets and Rent Ceilings

A. The 1906 earthquake in San Francisco left 200,000 people homeless, but the housing shortage was eliminated within a month. The market response to the earthquake was as follows:

1. As illustrated in Figure 7.1, in the short-run the earthquake shifted the short-run supply curve of housing leftward. Thus the rent rose from $16 per month before the earthquake to $20 per month after the quake while the quantity of housing fell from 100,000 to 74,000. (These are the same prices and quantities used in the text.) However, there was no shortage of housing as the higher price motivated suppliers to rent more space and encouraged demanders to rent smaller spaces.

2. In the long run the supply of housing is perfectly elastic. Hence in the long-run the equilibrium quantity of housing and the rental rate of housing returned to their initial levels of 100,000 and $16 per month.

B. A regulated housing market operates much differently from a free one. Regulation usually consists of imposing a rent ceiling, which is an example of a price ceiling. Rent ceilings are laws that prohibit charging rent higher than some maximum amount.

1. If the rent ceiling is below the equilibrium price, the quantity demanded exceeds the quantity supplied. In this case, the quantity actually bought and sold equals the quantity supplied.

2. When the quantity demanded exceeds the quantity supplied, potential buyers search for suppliers with goods available for sale. Search is costly to buyers. Therefore the total opportunity cost of housing equals the rent plus the opportunity cost of the search activity.

3. In addition to search, excess demand creates black markets, or illegal trading arrangements wherein buyers and sellers transact at prices above the legal maximum.

4. Rent ceilings create inefficiency and a deadweight loss, as illustrated in Figure 7.2.

5. New York City has had rent ceilings since World War II. These rent ceilings have caused the abandonment of blocks of apartments.

II. The Labor Market and the Minimum Wage

A. Decreases in the demand for unskilled labor constantly occur because of technological advances.

B. In an unregulated labor market, a decrease in the demand for unskilled labor causes a short-run decline in wages (as the demand curve shifts leftward along a positively sloped short-run supply curve of labor), and in the long run no change in wages (if the long-run supply of labor is perfectly elastic).

C. A labor market may be regulated with a minimum wage law, that is, a lowest legal wage that can be paid. In this case, a decrease in demand cannot cause a lower wage, so the quantity supplied of unskilled help exceeds the quantity demanded and unemployment results.

1. Some economists (David Card and Alan Krueger) recently suggested that minimum wage laws do not cause unemployment. However, other economists disagree and most believe that higher minimum wage laws cause more unemployment.

2. A minimum wage law creates inefficiency.

5. Economics in Action Tutorial

A.  Insert your CD-rom in your computer. 
Double-click MyComputer and select your CD-rom drive.  Then do Step B.

B.  Before you can use Economics in Action for the first time, you must  double-click on the setup icon opening one of two folders having icons that look likeTVs with  blue screens and click/run the setup.exe file within that folder.   (Ignore the blue screen TV which also has the Microsoft Internet Explorer icon associated with it.) Then go on to Step C.

C.  When you accomplish Step B., your execute software file will prompt you to restart your computer so that the new settings and the EIA 5.0 icon can hereafter be seen.  From here on your efforts to open the Economics in Action 5.0 CD-rom can be accomplished by inserting your EIA 3.0 CD-rom in its drive, followed by following by selecting and clicking your mouse on the sequence listed in Step D.

D.  Click Start;
Select Programs;
Locate and select the  EIA 5.0 program;
When your mouse identifies the EIA 5.0 program a sub-menu opens;
click the red EIA 5.0 icon.
This brings you to the opening screen within Economics in Action 5.0

E.  To become acquainted with EIA 5.0, click on Using EIA.

F.   When you are comfortable with Using EIA, click on any of the tutorial headings shown on EIA 5.0's opening screen.

G.  The first tutorial of major importance for this course is called Markets in Action located at the lower left side of the opening screen.

The Markets in Action section was created especially for this chapter.  Go ahead and complete the Markets in Action section on your own.

H.  If you are having difficulty installing or getting your Economics in Action 5.0 to work, contact the technical assistant for this course:

6. Let's begin Questions and Problems (study guide pages 101 - 106))

The important true or false, multiple choice,  and problems are those associated with the first three course objectives in which you seek to understand the economics of:

bullet

Housing Markets and Rent Ceilings;

bullet

The Labor Market and the Minimum Wage;

bullet

Taxes.

7. Homework

1.  Review Key Concepts pages 97- 99 in your study guide.
2.  Complete the odd-numbered Questions from your study guide pages 100 - 106 and check your answers using pages 107 - 112.
3.  Compare your class notes and your understanding of the homework Questions with your study partner.

8. Complete the Summary of  Key Points (using text page 146)

Housing Markets and Rent Ceilings

1.  A decrease in the supply of housing decreases short-run supply and increases the equilibrium rent.

2.  The higher rent increases the quantity of housing supplied in the short run and stimulates building in the long run.  The rent decreases, and the quantity of housing increases.

3.  I f a rent ceiling prevents the rent from increasing, the quantity supplied remains constant and there is a housing shortage, which creates wasteful search and black markets.

The Labor Market and the Minimum Wage.

4.  A decrease in the demand for low-skilled labor lowers the wage rate and reduces employment.

5.  The lower wage rate encourages people with low skill to acquire more skill, which decreases the supply of low-skilled labor.  The wage rises gradually to its original level, and employment decreases.

6.  Imposing a minimum wage above the equilibrium wage creates unemployment and an increase in the amount of time people spend searching for a job.

7.  Minimum wages hit young people who have the fewest skills hardest.

Taxes

8.  When a good or service is taxed, usually the price increases and the quantity bought decreases but the price increases by less than the tax.   The buyer pays part of the tax and the seller pays part of the tax.

9.  The portion of the tax paid by the buyer and by the seller depends on the elasticity of demand and the elasticity of supply.

10.  The less elastic the demand and the more elastic the supply, the greater is the price increase, the smaller is the quantity decrease, and the larger is the portion of the tax paid by the buyer.

11.  If demand is perfectly elastic or supply is perfectly inelastic, the seller pays the entire tax.  If demand is perfectly inelastic or supply is perfectly elastic, the buyer pays the entire tax.
