What is the difference between “diminishing marginal returns” and “diseconomies of
scale”?
A) Both concepts explain why marginal cost increases after some point but diminishing
marginal returns applies only in the short run when there is at least one fixed factor,
while diseconomies of scale applies in the long run when all factors are variable.
B) Both concepts explain why average total cost increases after some point but
diminishing marginal returns applies only in the short run when there is at least one
fixed factor, while diseconomies of scale applies in the long run when all factors are
variable.
C) Diminishing marginal returns, which applies only in the short run when at least one
factor is fixed, explains why marginal cost increases, while diseconomies of scale,
which applies in the long run when all factors are variable, explains why average cost
increases.
D) Diminishing marginal returns, which applies only in the long run when all factors
are variable, explains why average variable cost increases, while diseconomies of scale,
which applies in the short run when at least one factor is fixed, explains why average
total cost increases.
