Question

what does constant returns to scale mean?
production becomes inefficient with increasing scale.
the opportunity cost increases with output growth.
expanding all inputs proportionately does not change average cost.
average costs decrease as output increases.
the marginal output increases with additional inputs.
question 5
what is diminishing marginal productivity?
revenue decreases with rising costs.
total fixed cost increases with production.
variable inputs decrease with output growth.
more labor eventually produces less additional output.
more labor produces increasing marginal output.
question 6
what are diseconomies of scale?
production becomes perfectly efficient at large scale.
fixed costs are reduced proportionately to variable inputs.
long - run average costs increase as total output increases.
the marginal product of labor increases indefinitely.
costs decrease with increasing output over time.

Explanation:

Constant returns to scale in economics mean that when all inputs are increased proportionally, the average cost of production remains the same. Diminishing marginal productivity refers to the situation where adding more of a variable input (like labor) eventually leads to a smaller increase in output. Diseconomies of scale occur when long - run average costs rise as total output increases.

Answer:

Question 1: Expanding all inputs proportionately does not change average cost.
Question 5: More labor eventually produces less additional output.
Question 6: Long - run average costs increase as total output increases.
