When does a production function satisfy decreasing returns to scale?
Open in App
Solution
Decreasing
returns to scale (DRS) holds when a proportional increase in all the
factors of production leads to an increase in the output by less than
the proportion. For example, if both labour and capital are increased
by ‘n’ times but the resultant increase in output
is less than ‘n’ times, then we say that the
production function exhibits DRS.
Algebraically,
DRS exists when
f(nL,
nK) < n. f(L, K)
