False
The demand for seats in 10 am. classes at the university is higher than the demand for seats in 8 am. classes. The supply is fixed. If the university prices classes at the price required to achieve equilibrium at 10 am, there will be:
A surplus at 8 am.

Building more freeways, raising the price to drive on the freeway at 8 am, and encouraging workers to carpool
If income elasticity of demand is 2.12, it means that quantity demanded will by 2.12% for every in income.
Rise; 1.0% rise
An inferior good is:
A good for which the demand rises as income fails
If supply is perfectly inelastic, it follows that a:
Both “rise in price will not change quantity supplied,” and “fall in price will not change quantity supplied” are correct
If supply is inelastic, it follows that:
– Quantity supplied always changes more than price changes
– A rise in price will not change quantity supplied
– A fall in price will not change quantity supplied
– Consumers will pay 100% of any tax placed on sellers
None of these answers is correct.
Airlines that try to lower fares to increase revenue believe the demand for airline service is:
Price elastic
The MU/P ratio for good X is greater than the MU/P ratio for good Y. To achieve consumer equilibrium, the consumer reallocates dollars from the purchase of good Y to the purchase of good X. If the law of diminishing marginal utility holds, the marginal utility of good X______ and the marginal utility of good Y_______
Falls, rises
The budget constraint cuts the horizontal axis at 12 units of good X and it cuts the vertical axis at 20 units of good Y. If the price of good X is \$20 and the price of good Y is \$12, then what does income equal?
\$240
The 100th game of chess gives Jones more utility than the 32nd game of chess. It follows that:
The law of diminishing marginal utility may hold, since the 32nd game of chess might have been a different “good” than the 100th game of chess (after all, it could have been played with a different person)
When people treat some dollars differently than others, they are said to be compartmentalizing.

When the perfectly competitive firm produces the quantity of output at which marginal revenue equals marginal cost,
it naturally:
Produces the quantity of output at which marginal cost equals price, since for the perfectly competitive firm price equals marginal revenue
In a perfectly competitive market, the market demand curve is perfectly elastic.
False
Marginal revenue is:
The change in total revenue brought about by selling an additional unit of the good
For a perfectly competitive firm, the demand curve is horizontal at the price determined in the market.
True
A perfectly competitive market is initially in long-run competitive equilibrium. Then, market demand increases. As a result:
The marginal revenue curve for each firm shifts upward, and the demand curve for each firm shifts upward
If, for a perfectly competitive firm, marginal cost is greater than marginal revenue for the 100th unit, then it follows that:
Producing the 100th unit adds more to total cost than it does to total revenue; and the firm is not maximizing profit, or minimizing losses, if it produces the 100th unit
In long-run competitive equilibrium, firms:
Have no incentive to make any changes
One of the reasons why economies of scale exist is that the opportunity for labor specialization increases as the size of the firm grows.
