b.Because a demand curve is the graphical representation of the law of demand, which specifies a direct relationship between price and quantity supplied, ceteris paribus.

c.Because a demand curve is the graphical representation of the law of demand, which specifies an inverse relationship between price and demand, ceteris paribus.

d.Because a demand curve is the graphical representation of the law of demand, which specifies a direct relationship between price and demand, ceteris paribus.

e.Because a demand curve is the graphical representation of the law of demand, which specifies an inverse relationship between price and quantity demanded, ceteris paribus.

a.complements.

b.normal goods.

c.inferior goods.

d.substitutes.

e.none of the above

119.Which of the following statements is false?

a.The shift factors for the supply curve are: income, preferences, prices of related goods, the number of buyers, and expectations of future price.

b.A change in (own) price changes the quantity supplied of a good.

c.A change in demand is graphically represented by a shift in the demand curve.

d.A change in quantity demanded is represented by a movement along a given demand curve.

120.If potential buyers of good X expect the price of good X will soon fall, then the current

a.demand for good X will rise.

b.demand for good X will remain unchanged.

c.demand for good X will fall.

d.quantity demanded of good X will fall.

e.quantity demanded of good X will rise.

121.Which of the following statements represents a correct and sequentially accurate economic explanation?

a.X and Y are substitutes. The price of X falls, the quantity demanded of X rises, and the demand for Y rises.

b.X and Y are substitutes. The price of X rises, the demand for X falls, and the demand for Y rises.

c.X and Y are substitutes. The price of X falls, the demand for X rises, and the quantity demanded of Y rises.

d.X and Y are substitutes. The price of X falls, the quantity demanded of X rises, and the demand for Y falls.

e.X and Y are complements. The price of X falls, the quantity demanded of X rises, and the demand for Y falls.

122.Which of the following statements represents a correct and sequentially accurate economic explanation?

a.X is an inferior good and Y is a substitute for X. Income rises, the demand for X falls, the price of X falls, and the demand for Y rises.

b.X is an inferior good and Y is a substitute for X. Income rises, the demand for X falls, the price of X falls, and the demand for Y falls.

c.X is an inferior good and Y is a substitute for X. Income falls, the demand for X rises, the price of X rises, and the demand for Y falls.

d.X is an inferior good and Y is a substitute for X. Income rises, the quantity demanded of X rises, the price of X rises, and the demand for Y falls.

e.none of the above
