# One firm is better at producing everything than another

Suppose there are two goods, video cassettes and record albums, produced by firm A and firm B. Suppose the marginal rate of product transformation (RPT) of record albums for video cassettes in firm B is 2(That is, firm B can always trade 2 video cassettes for 1 record album in production). On the other hand, the RPT in firm A is 1. Assume that each firm's RPT is constant over all possible output combinations.
