									                 Note Sheet – SUPPLY                      [assume perfectly competitive markets]
41. Supply – quantities producers offer at each (technique/price).
42. The relationship between price and QS is (direct/inverse) and the relationship
    between price and QD is (direct/inverse) or opposite.
43. The “law of supply” indicates that producers will offer (less/more) at higher prices.
44. In moving along a stable supply or demand curve, (income/price) is not held constant.

45. (Inelastic/Elastic) supply – supply that is very responsive to price.
46. (Inelastic/Elastic) supply – when a change in price has little impact on QS.
47. The three-item test for elastic supply is: the item can be made quickly,
    it tends to be cheap, and it can be produced by (skilled/unskilled) workers.
48. The three-item test for inelastic supply is: the item cannot be made quickly,
    it tends to be expensive, and (skilled/unskilled) workers are needed to produce it.
49. An example of inelastic supply is (posters/computers/T-shirts).
50. An example of elastic supply is (HDTV/computers/T-shirts).
51. The supply curve for elastic supply is more (flat/vertical).
52. The supply curve for inelastic supply is more flat/vertical).
53. A reduction in the price of cattle feed will cause the (demand/supply) curve for beef to shift.
