As the price goes up…

Quantity goes:

As the price goes down…

Quantity goes:

Summary: Consumers want (more/fewer) goods and services at higher prices than they do at lower prices.

2. Fill in the direction of quantity:

Price Quantity

As the price goes up…

Quantity goes:

As the price goes down…

Quantity goes:

Summary: People buy (more/fewer) goods and services at higher prices than they do at lower prices.

Consider this:

If there was an increase in demand for CDs what would that mean?

If there was an decrease in demand for CDs what would that mean?

6 Factors Shifting Demand

1. Number of Consumers= how many people live in a certain area

5.Who has more consumers, Raleigh or Northampton?

2. Consumer Disposable Income=income left over after you buy necessary items

6. Quick Review: What is the name of the tax we put on these “extra” goods?

7. What is consumer disposable income?   

3. Consumer Tastes=popularity of the product

4. Consumer Expectations=what consumers expect to happen in the future

5.Substitutes=competing products that can be exchanged if the price of one increases

Substitute of hamburgers:

Substitute of cars:

6. Complementary Goods=products that are used together

Complement of peanut butter:

Complement of French fries:

Demand Shift Practice

Try it on your own!!

10 minutes to complete in groups, then correct as a class

If US Gov’t gave citizens a tax credit ($$$) then people would have more money to spend (more disposable income). Would demand increase or decrease?

Demand Factor Increase or Decrease?

DVD players have become popular among consumers. What happened to demand for DVDs?

Demand Factor Increase or Decrease?

Consumers expect that a new version of the iPod will come out around Christmas. What happened to demand for the OLD iPod?

Demand Factor Increase or Decrease?

Demand Factors

Dell raised the price of its laptops, so consumers started to buy the lower priced Sony laptop. What happened to demand for Dell laptops?

Demand Factor Increase or Decrease?

A new housing development was built in Enfield. Did the number of consumers in Enfield increase or decrease? So what happened to demand?

Demand Factor Increase or Decrease?

Consumers who used to prefer board games now prefer video games. What happened to demand for board games?

$.50 1

$1.00 2

$1.50 5

$2.00 7

$2.50 8

Use the table below to draw the supply curve:

11. Fill in the direction of quantity:

Price Quantity

As the price goes up…

Quantity goes:

As the price goes down…

Quantity goes:

Summary: Producers make (more/fewer) goods and services at higher prices than they do at lower prices.

14. Predict: If it becomes cheaper to make something (like an iPod)…the cost of production goes down…what do you think would happen to the quantity supplied?

5 Factors Shifting Supply1. Number of

Suppliers=more businesses making a good=more supply of the good

2. Government Regulations=tighter government regulations (control) make it more expensive to make goodssupply decreases.

15. What are some examples of government regulations?

3. Taxes=Higher taxes raise business costsif a business has to pay more money to the gov’t, it has less to spend on factors of productionso supply decreases.

16. Illustrate how taxes work.

4. Subsidies=gov’t money given to businesses, people, or a group to help them out (reduces the cost of production)

5. Producer Expectations=if producers think that consumer demand is going to drop, they will reduce supply; if they think demand will increase, they will increase supply.

17. What are some other examples of subsidies?  

23. If tape makers expect people to want CDs, what happens to supply? Why?

Supply Shift Practice

Congress gave all corn producers a subsidy for each bushel of corn they produce. Did the cost of corn production go up or down? Did the supply of corn increase or decrease?

Supply Factor Increase or Decrease?

Congress raised the minimum wage from $6.55 an hour to $7.25. What is the impact for fast food restaurants? Did the supply of fast food increase or decrease?

Supply Factor Increase or Decrease?

Congress cut the tax on American corporations to try and boost production in the United States. Did costs for corporations go up or down? Did supply increase or decrease?

Supply Factor Increase or Decrease?

A new shopping plaza opened on Highway. Did the # of suppliers increase or decrease? Did supply increase or decrease?

Supply Factor Increase or Decrease?

As the weather gets warmer near the end of the school year clothing stores expect consumers will want to buy summer clothes. Did the supply of winter clothes increase or decrease? Did the supply of SUMMER clothes increase or decrease?

Supply Factor Increase or Decrease?
