Percent Changes
At the starting point, all firms have the same
capital-to-labour ratio.
After the increase in the price of labour,

and experiences the smaller percent
reduction in profit.
Why? Greater ease of substitution enables a
firm to partially offset/avoid the input price
increase by more than the other firms.
