Which of the following statements about demand curves is TRUE?
If price falls and quantity demanded increases, this is represented by a movement along a given demand curve.
If price falls and quantity demanded increases, this is represented by a shift of the demand curve.
If price falls and quantity demanded increases, this can be represented by either a movement along a given demand curve, or a shift of the demand curve.
None of the above are true
Which of the following is NOT a determinant of the DEMAND for good X?
The income of consumers who buy good X.
The cost of labor used to produce good X.
The price of good Y, a complement to X.
The number of buyers of good X.
Which of the following will result in a DECREASE in DEMAND (i.e., a leftward shift of the demand curve)?

The diagram below illustrates 3 possible demand curves for coconuts. Suppose that coconuts and pineapples are substitutes. If the price of pineapples increases, which of the following movements will represent the effect of this in the market for coconuts?

B to E
Which of the following will NOT shift the market supply curve of good X

Suppose the equilibrium price of good X is $10 and the equilibrium quantity is 60 units. If the price of good X is $4:
The quantity demanded will be less than 60 units
The quantity supplied will be more than 60 units
There will be an excess demand for good X
There will be an excess supply of good X
