What is Demand?
Quantities of a particular good or service that people are willing and able to buy at different possible prices.
![Page 2: Quantities of a particular good or service that people are willing and able to buy at different possible prices.](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649e735503460f94b72aba/html5/thumbnails/2.jpg)
The Law of Demand
Consumers buy more of a good when its price decreases and less of a good when its price increases.

What is supply?
Supply: The amount of a product that is offered for sale at all possible prices in a market.
![Page 12: Quantities of a particular good or service that people are willing and able to buy at different possible prices.](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649e735503460f94b72aba/html5/thumbnails/12.jpg)
The Law of Supply
The Tendency of suppliers to offer more of a good/service at a higher price and less of that good/service at lower prices.

So…

Factors of Supply
Costs of inputs (factors of production)
![Page 16: Quantities of a particular good or service that people are willing and able to buy at different possible prices.](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649e735503460f94b72aba/html5/thumbnails/16.jpg)
Factors of Supply
Changes in productivity.

Factors of Supply
Change of the number of sellers in a market.
More sellers in a market = increased supply
Less sellers in a market = decreased supply

The Best Price!
The equilibrium price is the best price where supply and demand intersect. This is the point where suppliers and
consumers are in perfect harmony.

Price Controls
In an unregulated market system with open entry and exit, market forces establish equilibrium prices and quantities.
While equilibrium conditions may be efficient, not everyone will be satisfied with the outcomes. Consumers Producers 3 Economic Questions – Can’t please
everyone

Price Controls
Are usually enacted when policymakers believe the market price is unfair to buyers or sellers.
Result in government-created price ceilings or price floors.
![Page 22: Quantities of a particular good or service that people are willing and able to buy at different possible prices.](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649e735503460f94b72aba/html5/thumbnails/22.jpg)
Price Ceilings and Price Floors
Price Ceiling A legally established maximum price at
which a good can be sold.
Price Floor A legally established minimum price at
which a good can be sold.
![Page 23: Quantities of a particular good or service that people are willing and able to buy at different possible prices.](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649e735503460f94b72aba/html5/thumbnails/23.jpg)
Price Ceilings
There are 2 possible outcomes when dealing with price ceilings.
The price ceiling is not binding if set above the equilibrium price.
The price ceiling is binding if set below the equilibrium price, leading to a shortage.

Non-Binding Price Ceiling

Distribution Methods
Scarcity leads to consumers bidding up the price until the demand and supply reach an equilibrium.
![Page 29: Quantities of a particular good or service that people are willing and able to buy at different possible prices.](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649e735503460f94b72aba/html5/thumbnails/29.jpg)
Price Ceilings
What are price ceilings?
What if there are price ceilings on a product? (perhaps gas?)
What can that company do to fight the shortage, without raising prices, so they aren’t faced with losses?
![Page 30: Quantities of a particular good or service that people are willing and able to buy at different possible prices.](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649e735503460f94b72aba/html5/thumbnails/30.jpg)
Price Ceilings! Price ceiling can cause a shortage in
supply.• A ceiling forces a
company to produce less of a certain product, thus causing a shortage.
• With a low supply, but an extremely high demand, the company must make tough decisions about distribution.
![Page 31: Quantities of a particular good or service that people are willing and able to buy at different possible prices.](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649e735503460f94b72aba/html5/thumbnails/31.jpg)
Solution:
Limit the hours of when gas will be sold, cut costs on employees and storefront. Sell the good in a shorter period of time.
Black Market! Sell gas at a higher price to those who are
willing to pay for it. (let the equilibrium set the price)
No gov’t regulation in an illegal market. In a shortage situation, some people will be
left without gas and others will have a surplus.
![Page 32: Quantities of a particular good or service that people are willing and able to buy at different possible prices.](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649e735503460f94b72aba/html5/thumbnails/32.jpg)
Black Market
If some people have access to the gas, they will buy as much as they can and then sell at a higher price in the black market.
In the black market, there is no gov’t regulation; thus, the price bidding returns, reestablishing an equilibrium in price, supply, and demand. This will alleviate the shortage.
What are the opportunity costs of operating in a black market?
