  1. Intro to Market Equilibrium

  2. Market Equilibrium • Also referred to as Market Clearing Price • Quantity supplied = Quantity Demanded • This price “clears” the market • There is neither a surplus nor a shortage

  3. Does the Market Clearing Price leave everyone in the market satisfied? • NO: • Everyone who wants to buy goods at lower prices are not satisfied • Any producer who wants to sell at higher prices are not satisfied

  4. When buyers are left out of the market = SHORTAGE • Quantity demanded > Quantity supplied • The shortage is = to the difference between quantity supplied and quantity demanded • Price is BELOW market clearing price

  5. Once a shortage exists in the market, it will begin moving towards equilibrium • HOW? • Buyers begin competing for the amount available 1) Buyers willing to pay more for goods 2) Many buyers will reduce the amount they want to consume as price slowly increases 3) Producers will begin putting more quantity on the market as the price increases

  6. When sellers want to sell more than buyers want to buy = SURPLUS • Quantity supplied > Quantity demanded • The shortage is = to the difference between quantity supplied and quantity demanded • Price is ABOVE the market clearing price

  7. Once a surplus exists in the market, it will begin moving towards equilibrium 1) Sellers begin competing with one another for customers and decrease their prices 2) At these lower prices, some sellers will begin decreasing the quantity supplied 3) Once the sellers begin slowly lowering prices, more buyers begin entering the market

  8. Can their be a surplus of scarce goods? • In economics, a surplus simply means people don’t want to buy goods at a certain price • The question deals with a difference between WANTS and DEMANDS • Demands are wants that can be backed up with the ability to pay for goods

  9. Surplus, Shortage, or Equilibrium? • A Lady Gaga concert will take place in 6 months. Tickets are $120 per person. The concert has been sold out for a month, and people have now begun searching for tickets on Craigslist. Some of these tickets are now selling for $500.

  10. Surplus, Shortage, or Equilibrium? • The Sabres are selling tickets for $50 per seat, per game. You can buy a ticket the day of the game without waiting in line. Of the 18,690 seats in the arena, only 10,000 people are attending the game.

  11. Surplus, Shortage, or Equilibrium? • Loganberry has been selling at $3 per 6-pack for the past 8 months at Wegmans. You can buy a 6-pack any time you enter Wegmans, and Wegmans never runs out before the next shipment from the supplier.

  12. What are the functions of price in a market system? • Prices send SIGNALS (information) • When prices are high • Sellers take the signal as the OK to produce more • Buyers will purchase less -- When prices are low • Sellers will produce less • Buyers will increase purchases

  13. What are the functions of price in a market system? • Prices Ration • Ration scarce goods among people who want more goods than are available • Whoever is willing and able to pay the market price

  14. What are the functions of price in a market system? • Prices Motivate • Provide incentives for people to produce goods and services • Help decide what to produce and how produce

  15. Changes in Prices and Production • Because the supply or demand for a product can change, each market clearing price is likely to rise or fall over time

  16. Chapter 5 NOTES Market-Clearing Price

  17. Demand and Supply • Chapter 3—Market demand shows that consumers buy less if prices go up. • Chapter 4—Market supply shows that producers produce more if prices go up.

  18. Market Clearing Price • Market Clearing Price—is the price that balances the amount buyers want to buy with the amount sellers want to sell. • This price is also called the market equilibrium. • It is the point where the supply curve and the demand curve intersect.

  19. Activity • Copy chart 5-1 on page 38 into your notebook.

  20. Shortage • Shortage—How much more of a product buyers want to buy than sellers want to sell at a given price. • To calculate shortage, subtract the number that buyers demand at a particular price by the number producers are willing to produce at that price. • Copy Chart 5-2 into your notebook

  21. Surplus • How much more of a product sellers want to sell than buyers want to buy at a given price. • To calculate surplus, subtract the number of goods a producer is willing to sell at a particular price by the number of goods consumers want to buy at that same price. • Copy Graph 5-3 into your notebook.

  22. Prices that Ration • Rationing—Distributing or allocating a product. • In a free-market economy, goods are rationed through market prices.

  23. Prices that Motivate • Besides rationing, market prices also provide incentives for people to produce goods and services.

  24. Changes in Price and Production • Look at chart 5-6 in your text book (p.42) • In your groups, come up with two reasons why you think the “Fortune 500” companies have changed over the last 50 years.
