The VCR manufacturing business is perfectly competitive. Suppose that currently, firms
which manufacture VCR's utilize either technology 1 or technology 2, whose cost functions are
given below:
TC1(Q) = 1060-60Q+Q^2
TC2(Q) = 220 - 20Q + Q^2
In the long run, assuming no new manufacturing technologies, what will happen in this industry?
(a) Firms utilizing technology 1 will stay in business, and firrms utilizing technology 2 will also stay in
business.
(b) Firms utilizing technology 1 will stay in business, but firms utilizing technology 2 will shut down.
(c) Firms utilizing technology 1 will shut down, but firms utilizing technology 2 will stay in business.
(d) Firms utilizing technology 1 will shut down, and firms utilizing technology 2 will also shut down.
(e) None of the above.
答案是C 为啥捏？
然后关于这两个总成本函数，为什么会有常数项存在？若是长期成本函数，不应该TC1（0）= 0才对吗？而本题中为啥
TC1（0）= 1060    TC2（0）=220
