Many firms use odd pricing - charging prices such as $.99 instead of $1.00 and $9.99
instead of $10.00. One reason for this pricing strategy is that consumers will somehow
believe that the difference in price appears to be greater than it actually is. Researchers
conducted consumer surveys to determine whether this is actually the case. What was
the result of these surveys?
A) The surveys found that small differences in price cause small differences in quantity
demanded. There is no evidence that odd pricing makes economic sense.
B) Although the results were not conclusive, there is some evidence that odd pricing
makes economic sense.
C) The surveys found indifference regarding this strategy among most consumers, but
hostility among other consumers. The latter group resented what they viewed as an
attempt to fool them into buying products with odd prices. Researchers concluded that
odd pricing is counterproductive.
D) The survey results were inconclusive because most consumers gave unreliable
responses to the survey questions.

The demand curve for corn is downward sloping. If the price of corn, an inferior good,

identical firms each producing 5,000 units of output. The prevailing market price is $20.
Assume that each firm faces increasing marginal cost. Now suppose there is a sudden
increase in demand for the industry's product which causes the price of the good to rise
