2. Social security programs are aimed at making the distribution of resources in an

the value of the property and resources used at their next best alternative use.
c.
the value of the property and resources used at all of their alternative uses.

infinite, and so we cannot estimate it.
4. Suppose you are considering going to the movies, and you place a $12 value on your

5. Metro North Railway is trying to decide whether or not to run an additional train into
New York City from New Haven, Connecticut at 8:15 a.m. The total cost of running trains
between 8:00 a.m. and 9:00 a.m. is $45,000 and the expected revenues on any given day
are $100,000 during this time period. The cost of running the additional train is $4,000 and
it is expected that revenues will rise to $103,500. Metro North should ( d )
a.
run the train because the total revenues are greater than the total costs.
b.
run the train because the firm’s revenues will rise.
c.
not run the train because the total costs are already too high.
d.

marginal revenue of $3,500.
