First, as output is increased by the firms in the economy, diminishing returns to variable factors, especially to labour, accrue resulting in fall in marginal physical product (MPPL) of labour. With money wage rate (W) as given and ‘ fixed, the fall in the marginal physical product of labour causes the rise in the marginal cost (MC) of production (Note that MC= W/MPPL). With the fall in the MPP of labour, wage rate remaining constant, the term W/MPPL measuring marginal cost (MC) will rise. Read more
