8. Section 1 The Law of Demand The law of demand states that as price goes up, quantity demanded goes down, and vice versa.

9. VS 1 The law of demand states that as price goes up, quantity demanded goes down. As price goes down, quantity demanded goes up.

10. Section 1 The Law of Demand (cont.) Several factors explain the inverse relation between price and quantity demanded, or how much people will buy of any item at a particular price.quantity demanded –Real income effectReal income effect –Substitution effectSubstitution effect Factors include:

11. Vocab7 real income effect: economic rule stating that individuals cannot keep buying the same quantity of a product if its price rises while their income stays the same substitution effect: economic rule stating that if two items satisfy the same need and the price of one rises, people will buy more of the other

12. Section 1 The Law of Demand (cont.) Diminishing marginal utility: –Utility - the ability of any good or service to satisfy consumer wantsUtility - –Marginal utility - an additional amount of satisfactionMarginal utility - –Law of diminishing marginal utility - the additional satisfaction a consumer gets from purchasing one more unit of a product will lessen with each additional unit purchasedLaw of diminishing marginal utility

29. Section 2 The Price Elasticity of Demand Elasticity of demand measures how much the quantity demanded changes when price goes up or down.

30. Section 2 The Price Elasticity of Demand (cont.) For some goods, a rise or fall in price greatly affects the amount people are willing to buy. This economic concept is referred to as elasticity.elasticity The measure of how much consumers respond to a given change in price is referred to as price elasticity of demand.price elasticity of demand View: Demand vs. Quantity DemandedDemand vs. Quantity Demanded View: Goods with…Goods with…

36. Section 3 Profits and the Law of Supply The law of supply states that as price goes up, quantity supplied goes up, and vice versa.

37. Section 3 Profits and the Law of Supply (cont.) To understand pricing, you must look at both demand and supply. –The higher the price of a good, the greater the incentive is for a producer to produce more. The law of supply states that as the price of a good rises, the quantity supplied also rises. As the price falls, the quantity supplied also falls.The law of supplyquantity supplied View: The Law of SupplyThe Law of Supply

39. Section 3 The Supply Curve A supply curve is a graph that shows the relationship between price and quantity supplied.

40. VS 2 The law of supply states that as price goes up, quantity supplied also goes up. As price goes down, quantity supplied goes down.

44. Section 3 The Determinants of Supply A change in the supply of a particular item shifts the entire supply curve to the left or right.

45. Section 3 The Determinants of Supply (cont.) Many factors affect the supply of a specific product. Four of the major determinants are: –The price of inputs –The number of firms in the industry –Taxes imposed or not imposed View: If Inputs Become CheaperIf Inputs Become Cheaper View: If Number of Firms IncreasesIf Number of Firms Increases View: If Taxes IncreaseIf Taxes Increase

53. Section 3 The Law of Diminishing Returns When a business wants to expand, it has to consider how much expansion will really help the business.

54. Section 3 The Law of Diminishing Returns (cont.) Will product output continue to increase proportionally as more workers are hired? The law of diminishing returns shows that as more units of a factor of production are added to the other factors of production, after a certain point, the extra output for each additional unit hired will begin to decrease.The law of diminishing returns View: Supply vs. Quantity SuppliedSupply vs. Quantity Supplied View: Diminishing ReturnsDiminishing Returns

56. Section 4 Equilibrium Price In free markets, prices are determined by the interaction of supply and demand.

57. Section 4 Equilibrium Price (cont.) Demand and supply operate together. As the price of a good goes down, the quantity demanded rises and the quantity supplied falls (and vice versa). The point at which the quantity demanded and quantity supplied meet is called the equilibrium price. equilibrium price View: Equilibrium PriceEquilibrium Price View: Change in Equilibrium PriceChange in Equilibrium Price

60. Section 4 Prices as Signals Under a free-enterprise system, prices function as signals that communicate information and coordinate the activities of producers and consumers.

61. Section 4 Prices as Signals (cont.) Rising prices signal producers to produce more and consumers to purchase less. Falling prices signal producers to produce less and consumers to purchase more. A shortage occurs when at the current price, the quantity demanded is greater than the quantity supplied.shortage Prices above the equilibrium price reflect a surplus to suppliers. (quantity supplied > quantity demanded at current price. surplus

62. Section 4 Prices as Signals (cont.) When a market economy operates without restriction, it eliminates shortages and surpluses. –When a shortage occurs, the price goes up to eliminate the shortage. –When surpluses occur, the price falls to eliminate the surplus.

64. Section 4 Price Controls Under certain circumstances, the government sometimes sets a limit on how high or low a price of a good or service can go.

65. Section 4 Price Controls (cont.) –Effective price ceilings, and resulting shortages, often lead to non-market ways of distributing goods and services such as rationing and leading to the black market.rationing black market A price ceiling is a government-set maximum price that may be charged for a particular good or service.price ceiling View: Price Ceilings and Price FloorsPrice Ceilings and Price Floors
