QUESTION 2

A manufacturer of frozen pizzas found that total revenue decreased when price was lowered from $5 to $4. It was also found that total revenue decreased when price was raised from $5 to $6. Thus,

  • the demand for pizza is inelastic above $5 and elastic below $5
  • the demand for pizza is elastic both above and below $5
  • the demand for pizza is elastic above $5 and inelastic below $5
  • $5 is not the equilibrium price of pizza

QUESTION 4

A state government wants to increase the taxes on cigarettes to increase tax revenue. Because cigarettes are addictive, we would expect its demand to be

  • elastic. Thus, the governments cigarette-tax revenues would rise with a tax increase.
  • inelastic. Thus, the governments cigarette-tax revenues would fall with a tax increase.
  • elastic. Thus, the governments cigarette-tax revenues would fall with a tax increase.
  • inelastic. Thus, the governments cigarette-tax revenues would rise with a tax increase.

  • substitutes goods.
  • normal goods.

QUESTION 9

If demand for farm crops is inelastic, a good harvest will cause farm revenues to

  • decrease because of a percentage fall in price that is greater than the percentage increase in quantity sold.
  • increase because of a downward movement along the supply curve, encouraging an increase in demand.
  • increase because of the increase in the quantity that farmers can sell.
  • remain unchanged, because the increase in quantity that can be sold will be matched by an equal decrease in price.
