  1. Warm-up Think back to Easter! • What was the price of Easter candy on Monday morning, compared to Saturday afternoon? • What is the need for Easter candy on Monday morning, comparedto Saturday afternoon?

  2. Supply and Demand Graphing, Notes, and Lots and Lots of Practice!!!

  3. The Basic Graph (aka “The Starting Point”)

  4. What do the letters mean? X axis = Q = Quantity Y axis = P = Price D = Demand S = Supply

  5. The Basic Graph (aka “The Starting Point”) Equilibrium

  6. What do the letters mean? “The Intersection” = Equilibrium (shows perfect supply/demand) P* = Equilibrium Price Q* = Quantity Demanded/Supplied (at the equilibrium price)

  7. Definition for Supply • The total amount of a good or service producers are willing and able to make at all prices at a specific point in time.

  8. or Law of Supply • States that as price increases (or decreases) the quantity supplied also increases (or decreases).

  9. Determinants - things that could shift (change) the SUPPLY of a product • Price and availability of land, labor and capital (OJ v. cold winter) • New technology (cotton gin) • Number of other sellers (grocery stores in M’town)

  10. Determinants – things that could shift (change) the SUPPLY of a product, cont. • Price of other goods someone could produce (fresh fruits and/or vegetables in the summer v. winter) • Taxes (if they increase overall cost goes up too)

  11. S2 S2 Graphing a Shift in Supply(start w/ the basic graph)

  12. Graphing a Shift in Supply • The NEW supply line (S2) is called the Supply Curve. That’s Crazy – it’s a straight line! (don’t let that throw you off)

  13. S2 P2 Q2 Graphing a Shift in Supply (show the new price/quantity)

  14. Definitions for Demand • The total amount consumers are willing and able to buy at all prices at a specific point in time.

  15. Law of Demand • States that as price increases (or decreases) the quantity demanded decreases (or increases). or

  16. Determinants - things that could shift (change) the DEMAND for a product • Tastes and fads (McNabb shirts) • Income (BMW dealerships) • Number of buyers (Burger King)

  17. Determinants - things that could shift (change) the DEMAND for a product, cont. • Future price expectations (SUVs when gas increases) • Price and availability of • Substitutes (Uggs v. no name) • Compliments (jam/jelly w/ PB)

  18. D2 D2 Graphing a Shift in Demand(start w/ the basic graph)

  19. Graphing a Shift in Demand • The NEW Demand line is called the Demand Curve. That’s Right Folks – it’s also a straight line!

  20. P2 D2 Graphing a Shift in Demand (show the new price/quantity) Q2

  21. I R D L Always remember it so you know whether to shift right or left(for either supply or demand). . .

  22. I R D L stands for . . . • Increase • Right • Decrease • Left

  23. Let’s Try It! Imagine you are reading a newspaper and come across the following headlines . . .

  24. Two Major Computer Manufacturers Build Five New Factories

  25. Two Major Computer Manufacturers Build Five New Factories • What is the market you are graphing? • Computers • Does it deal with Supply or Demand? • Supply • Does supply increase or decrease? • Increase • Does the supply curve shift to the right or left? • Right

  26. S2 P2 Q2 Supply of computers increases because more factories are built.

  27. Doctors announce benefits of eating ice cream daily Try Another

  28. Doctors announce the benefits of eating ice cream daily • What is the market you are graphing? • Ice Cream • Does it deal with Supply or Demand? • Demand • Does demand increase or decrease? • Increase • Does the demand curve shift to the right or left? • Right

  29. P2 D2 Demand for ice cream increases for health reasons Q2

  30. Car Manufacturer Announces Plans for SUV Price Increase in Two Months Here’s a Tricky One

  31. Don’t forget to ask the questions . . . • What is the market you are graphing? • Does it deal with Supply or Demand? • Does supply/demand increase or decrease? • Does the supply/demand curve shift to the right or left?

  32. P2 D2 Demand for SUVs NOW! Q2

  33. Always read the headline for what it is right now! Try not to read into it too much! Keep it simple!

  37. Don’t forget to ask the questions! • What is the market you are graphing? • Does it deal with Supply or Demand? • Does supply increase or decrease? • Does the supply curve shift to the right or left?

  38. P2 D2 Demand increases for Toyotas with great gas mileage Q2

  39. Protected Owls Discovered in Lumber Forest! Companies told to discontinue logging.

  40. Don’t forget to ask the questions! • What is the market you are graphing? • Does it deal with Supply or Demand? • Does supply increase or decrease? • Does the supply curve shift to the right or left?

  41. S2 P2 Q2 Supply of lumber (logging) decreases due to protection of owls
