I have a problem in economics on Scope of Economies. Please help me in the following question. Whenever the production of one good (example: milk) decreases the production costs of complementary products (that is, butter and cheese), a firm is capable to exploit the economies of: (i) Scope. (ii) Scale. (iii) Transaction costs. (iv) Information. (v) Structure.
What is the most precise answer from the above.
