product is small.

Both I and II are false.
I is true;II is false.
I is false;II is true.

Suppose that a consumer will only drink one cup of coffee (C) with one shot of vanilla

should the consumer buy?
4 cups of coffee and no vanilla syrup.
3 cups of coffee and 3 shots of vanilla syrup.
12 shots of vanilla syrup and no coffee.
4 cups of coffee and 12 shots of vanilla syrup.
In order to identity a consumer's demand curve from an optimal choice diagram, we
change the price of one good, holding income and the price of the other good
constant, and identify the baskets the consumer chooses with each price level.
change the consumer's income, holding the prices of both goods constant, and
identify the baskets the consumer chooses with each income level.
change the price's both goods, holding income constant, and identify the baskets the
consumer chooses with each price level.
change the price of one good and then change the income level so that the
consumer achieves the same level of utility as before the price change and then
identify the optimal consumption baskets at each price level.

Suppose that Bill, George, and AI constitute the entire market for consumers of
national defense. Each man has an identical demand curve for national defense, which
be can be expressed as P=50-Q. Suppose that the marginal cost for national defense
can expressed as MC=$30. What is the optimal quantity of national defense?

An environmental economic consulting firm is hired to measure the production
schedule for a coal-burning electric generating plant in such a way as to incorporate the
negative externalities associated with the pollution from the plant. The marginal social
cost of this plant's production can be expressed as MSC = 3Q +10 . Prior to the
consulting firm's report, the consultants asked the plant's manager for data to generate
the firm's supply schedule. The consultants calculate that the marginal private cost of
the plant's production can be expressed as MPC = Q +10 . The firm's demand curve
can be expressed as P = 60 − Q . If the consultants have accurately measured the
impact of the pollution externality, the cost of the externality is
greater than $572.
between $573 and $468.
between $468 and $312.
less than $312.
