Afreelance singer-songwriter is planning the restoration of a recently purchased civil war-era farmhouse. while he professes an enjoyment of, and talent in the construction trades, the theory of comparative advantage implies that
a) he ought to do as much of the work himself as possible since imports (in this case, professionalcontractor services) should always be restricted to those things that cannot be done internally.
b) the value of what he imports (in this case, professional contractor services) must equal the value ofwhat he exports (songs).
c) the income lost while away from music will likely exceed the savings realized by doing the workhimself, thus, he should hire professionals to do the restoration work.
d) he should concentrate on the restoration work since his out-of-pocket costs will be much lower than ifhe hires professionals.
e) self-sufficiency is advantageous, hence he should split his time between music and construction.
