Correct statements: A, B, C
A. Company output will be maximized if Calvin makes all the decals and Hobbes makes all the chains.
If they each focus on the skill they are most efficient at, production will be higher.
B. Calvin has a comparative advantage for making decals.
A comparative advantage is being able to do an activity better or more efficiently than someone else. Calvin's comparative advantage is that he is faster than Hobbes at making decals.
C. Hobbes has a higher opportunity cost for making decals than Calvin.
Because Hobbes is more efficient at chains, he is giving up the opportunity to produce at maximum efficiency if he decides to make decals instead. The lost production is the opportunity cost.
