This paper extends the Q-theory of investment to capital product with arbitrary potency profiles. Once potency is non-geometric, the firm’s capital stock and also the cost of its assets are essentially totally different aggregates of the firm’s investment history. If capital product has constant potency over a finite helpful life, easy proxies are promptly offered for each the cost of assets in situ and capital stock. Underneath this assumption, we have a tendency to decompose the full investment rate on 2 dimensions: into its web and replacement parts, and into its money and non-cash parts. We have a tendency to show these parts exhibit considerably totally different economic determinants and behavior. Most assets are in hand by the ï¬Â�rms that use them, in order that the costs and volumes of capital services don't seem to be directly discovered. Growth accountants use mensuration models for imputing values to those variables. They construct each productive stocks – that's, stocks of assets expressed in new equivalent units – and web stocks – that's, stocks of assets valued at second-hand costs. The volumes of capital services are taken proportional to the productive stocks. Internet stocks yield the amounts of depreciation and of interest on the cash endowed, which are the prices of owning and exploitation, the assets for one year. The imputed rental costs simply cowl these prices.
