Combining Resources
Up to this point we have analyzed the use of only one resource.
What about a
firm wants to
combine different
resources?
For consumers, we want Utility Maximization, which
means every penny we spend worth the money.
For producers, we want Cost Minimization, which
means every worker we hire worth the money.
