Investment, capital stock, and replacement cost of assets when economic depreciation is non-geometric


This paper extends the Q-theory of investment to capital goods with arbitrary efficiency profiles. When efficiency is non-geometric, the firm's capital stock and the replacement cost of its assets are fundamentally different aggregates of the firm's investment history. If capital goods have constant efficiency over a finite useful life, simple proxies are readily available for both the replacement cost of assets in place and capital stock. Under this assumption, we decompose the total investment rate along two dimensions: into its net and replacement components, and into its cash and non-cash components. We show these components exhibit significantly different economic determinants and behavior.
