A Regulated Housing Market
Price ceilings are regulations that make it illegal to charge a price higher than a specified level.
Rent ceilings (sometimes called rent control) are price ceilings applied to housing markets.
How does a rent ceiling affectthe housing market?
![Page 5: CHAPTER 6 Government Actions in Markets. Learning Objectives Explain how price ceilings create shortages and inefficiency (example, rent control) Explain](https://reader033.vdocuments.us/reader033/viewer/2022051400/5518acd4550346881f8b4d50/html5/thumbnails/5.jpg)
A Regulated Housing Market
Rent ceilings set above equilibrium have no effect.
Rent ceilings set below equilibrium prevents price from regulating the quantities supplied and demanded.

Rent Ceiling
Instead of letting the housing market adjust normally (P*=2000, Q*=72), suppose a rent ceiling of $1600 per month was imposed.

Effects of a Rent Ceiling
Because of the housing shortage, black markets develop. The maximum black market rent would be $2400.

Effects of a Rent Ceiling
For those who abide by the rent ceiling law, there is no incentive to maintain the existing housing stock. As a result, housing quality falls.
There is also no incentive to build new housing. Thus, a permanent shortage of housing could exist.

Effects of a Shortage When quantity demanded exceeds
quantity supplied, the smaller quantity will be the one actually bought and sold, many suppliers have nothing to sell, and many buyers find there is nothing to buy.
36,000 units are available. Demand for the additional 64,000
units is unsatisfied.

A Housing Market with a Rent Ceiling
Are Rent Ceilings Fair?According to the fair rules view, a rent ceiling is unfair because it blocks voluntary exchange.According to the fair results view, a rent ceiling is unfair because it does not generally benefit the poor.A rent ceiling decreases the quantity of housing and the scarce housing is allocated by Lottery First-come, first-served Discrimination
![Page 24: CHAPTER 6 Government Actions in Markets. Learning Objectives Explain how price ceilings create shortages and inefficiency (example, rent control) Explain](https://reader033.vdocuments.us/reader033/viewer/2022051400/5518acd4550346881f8b4d50/html5/thumbnails/24.jpg)
A Housing Market with a Rent Ceiling
A lottery gives scarce housing to the lucky.A first-come, first served gives scarce housing to those who have the greatest foresight and get their names on the list first.Discrimination gives scarce housing to friends, family members, or those of the selected race or sex.None of these methods leads to a fair outcome.

Labor Markets andMinimum Wages
The interaction of demand and supply in the labor market influences the jobs we get and the wages we earn.
Firms make decisions about the quantity of labor to demand.
Households make decisions about the quantity of labor to supply.
![Page 27: CHAPTER 6 Government Actions in Markets. Learning Objectives Explain how price ceilings create shortages and inefficiency (example, rent control) Explain](https://reader033.vdocuments.us/reader033/viewer/2022051400/5518acd4550346881f8b4d50/html5/thumbnails/27.jpg)
An UnregulatedLabor Market
The wage rate balances the quantity demanded and the quantity supplied, determining the level of employment.

The Minimum Wage
A minimum wage law is a regulation that makes hiring labor below a specified wage illegal.
In the U.S., the current federal minimum wage is $7.25/hour
Most states also have minimum wages. About 40% of the states have minimum
wages above the federal minimum. The larger of the federal or state minimum
is the one that applies to workers in that state.
![Page 30: CHAPTER 6 Government Actions in Markets. Learning Objectives Explain how price ceilings create shortages and inefficiency (example, rent control) Explain](https://reader033.vdocuments.us/reader033/viewer/2022051400/5518acd4550346881f8b4d50/html5/thumbnails/30.jpg)
Effective and Ineffective Minimum Wage Laws
If the minimum wage is set below the equilibrium wage, it has no effect.
If the minimum wage is set above the equilibrium wage, the minimum wage law is in conflict with market forces.
![Page 31: CHAPTER 6 Government Actions in Markets. Learning Objectives Explain how price ceilings create shortages and inefficiency (example, rent control) Explain](https://reader033.vdocuments.us/reader033/viewer/2022051400/5518acd4550346881f8b4d50/html5/thumbnails/31.jpg)
Effects of an Effective Minimum Wage Law
An effective minimum wage causes the supply of labor to exceed the demand for labor.
The excess supply of labor (surplus) is called unemployment.
The unemployed workers are searching for jobs. The unemployed are comprised of two groups
(layoffs and new entrants). In our example each of these groups has 1 million
workers for a total of 2 million unemployed. The minimum wage is inefficient and creates a
deadweight loss.

The Minimum Wagein Reality
Minimum wage laws hit low-skilled workers the hardest, especially the young with few job skills.
The unemployment rate for teenagers is consistently more than twice the national average.
The actual minimum wage is zero, the wage earned by the unemployed.
