1. The Market Never Stands Still

2. 1. According to the schedule and the graph, what is the equilibrium price and quantity demanded in this example? 2. Priced at $19, what is the surplus / shortage? 3. If there is a shortage of -800, then what was the price of the DVDs? Please write down the three questions below. Use the chart on page 195 to answer. Thanks.

3. SSEMI3 The student will explain how markets, prices, and competition influence economic behavior. a. Identify and illustrate on a graph factors that cause changes in market supply and demand. b. Explain and illustrate on a graph how price floors create surpluses and price ceilings create shortages. c. Define price elasticity of demand and supply.

4. How can changes in supply and demand be illustrated?

5. Determinants of Demand Change in consumer income Change in tastes and preferences Change in the price of a substitute good Change in the price of a complementary good Change in consumers’ price expectations Change in number of consumers in the market

13. Income – income increases, demand increases; income decreases, demand decreases

16. Determinants of Demand (from Cannon) (Things that shift the entire line!) R I P E N references – preferences increase, demand increases; preferences decrease, demand decreases

17. Preferences – preferences increase, demand increases; preferences decrease, demand decreases

20. Determinants of Demand (from Cannon) (Things that shift the entire line!) R I P E N xpectations – expect higher prices in future, current demand increases expect lower prices in future, current demand decreases

21. Expectations – expect higher prices in future, current demand increases expect lower prices in future, current demand decreases

23. Determinants of Demand (from Cannon) (Things that shift the entire line!) R I P E N umber of buyers – # of buyers increase, demand increases; # of buyers decrease, demand decreases

24. The demand for a particular good may increase or decrease due to more or less people in the market for the good. For example, before the advent of ecommerce (using the world wide web to buy and sell), most businesses sold products to people who lived in their area of the country or who ordered products from their mail order catalogs. As people began to use online shopping in greater numbers, many businesses with little or no web presence probably experienced a decline in consumers of their products due to increased competition from online businesses while businesses who quickly and effectively adapted to the ecommerce model probably saw an increase in consumers of their products. Number of buyers – # of buyers increase, demand increases; # of buyers decrease, demand decreases

30. One determinant of demand is the number of buyers in the particular market. The number of buyers can push the curve to the right or to the left. For example, the number of people who left Detroit, Michigan means the demand curve for homes has shifted to the left. Conversely, in Arizona, the rise in population has led to the curve to move to the right.

58. Please write down the following Supply and Demand Schedules; graph the supply and demand curve

59. On the graph paper provided, identify and label the following  Supply Curve and Demand Curve  the Equilibrium Point  Shortage and Surplus areas

60. SSEMI3 The student will explain how markets, prices, and competition influence economic behavior. a. Identify and illustrate on a graph factors that cause changes in market supply and demand. b. Explain and illustrate on a graph how price floors create surpluses and price ceilings create shortages. c. Define price elasticity of demand and supply.

61. What are price ceilings and price floors?

62. Price Floors and Price Ceilings Adam Smith felt that the government should never interfere in the free market …

63. Sadly, Adam Smith was a little bit off base, we need government to rein in free markets

65. Government price controls occur when a government decides to set a legal maximum or legal minimum price in a market for a good or service.

66. A price floor is a legal minimum price for a g, s, or fop Charging or paying a price below the price floor is illegal and can carry a penalty under the law.

67. The most familiar PF is the minimum wage. In the USA, it is illegal to pay less than $7.25 per hour. There are some classifications of workers who may not be subject to this requirement, but most are.

68. The government’s argument for a minimum wage stems from a belief that the market wage is not high enough to provide a reasonable standard of living for low skilled workers.

69. A price ceiling is a legal maximum price for a g, s, fop. Charging or paying a price above the price ceiling is illegal and can carry a penalty under the law.

70. The most familiar “PC” is the rent control. In some cities, the “ER” is viewed as too high for lower income people. Therefore, a city designates some housing units as rent control units.

71. Price ceilings usually create shortages in the market.

72. Price controls will often create underground markets. If the price floor minimum wage is truly too high for the market to bear, both workers and employers will choose to trade in the underground market. This is bad for government because it will not collect taxes on that income earned and it will have to spend resources to enforce the price floor. If the price ceiling rent is truly too low for the market, tenants will cheat by illegally subletting their rent controlled apartments to others, pocketing the difference. Landlords will have no incentive to keep apartments in good repair and the housing will become substandard. Eventually, the number of rent controlled units will decline as frustrated landlords convert their buildings to condominiums or sell off their property for alternative uses.
