b. As you expand output, your marginal productivity eventually declines
c. As you expand output, the total product eventually increases
d. None of the above
2. What are economies of scale?
a. decreasing average costs as production increases
b. increasing average costs as production increases
c. increasing fixed costs as production increases
d. none of the above
3. What are economies of scope?
a. lower average costs when multiple different products are produced
b. higher average costs when multiple different products are produced
c. Constant average costs when multiple different products are produced
d. none of the above

b. As you expand output, your marginal productivity eventually declines

a. decreasing average costs as production increases

a. lower average costs when multiple different products are produced

Explanation:

The law of diminishing marginal returns states that as more unit of variable factors of production are added to production, output would increase at first but after a period, it would increase at a negative rate.

Economies of scale is the reduction in cost thay accrue to firms as they increase production. For example, a supplier might give a firm a discount for buying in bulk.

Economies of scope states that average cost would fall as the production of similar products increases. For example, a fashion designer who makes women's clothings decides to make scarfs with the scraps of clothes left.
