Inflation Adjusted Economic Profit

Abstract

In this paper, we measure economic profit in an inflationary environment. Inflation adjusted economic profit requires two principal alterations to Economic Value Added (EVA[rgrave]). First, because inflation increases the replacement cost of non-current assets above book value, one must make a downward adjustment to EVA[rgrave] to correctly measure economic profit. Second, we add a term to EVA[rgrave] to represent a manager's ability to increase product price as costs increase. This adjustment is positive because this ability adds value to a firm. When a firm's assets are largely current, the first adjustment is not necessary, and therefore, the second dominates. In this case, EVA[rgrave] underestimates economic profit. Economic profit remains positive when a firm's rate of return on invested capital, after tax and after depreciation, is less than the weighted average cost of capital by as much as the rate of inflation. Even when inflation is modest, unadjusted EVA[rgrave] has the potential to seriously misrepresent the operating performance of a firm.
