Fixed Capital - Estimating The Value of Fixed Capital

Estimating The Value of Fixed Capital

Attempts have been made to estimate the value of the stock of fixed capital for the whole economy using direct enterprise surveys of "book value", administrative business records, tax assessments, and data on gross fixed capital formation, price inflation and depreciation schedules. A pioneer in this area was the economist Simon Kuznets.

Using the so-called "perpetual inventory method", one starts off from a benchmark asset figure, and adds on the net additions to fixed assets year by year, while deducting annual depreciation, all data being adjusted for price inflation using a capital expenditure price index. In this way, one obtains a time series of annual fixed capital stocks.

However, it is widely acknowledged that it is extremely difficult to obtain any accurate measurement of the value of fixed capital, especially because even the owner himself or herself may not know what the assets are currently "worth". What they are worth may become apparent only at the point where they are definitely sold for a price. Some valuations for fixed assets may refer to historic cost (acquisition cost) or book value, others to current replacement cost, current sale value in the market, or scrap value. The depreciation write-off permitted for tax purposes may also diverge from so-called "economic depreciation" or "real" depreciation rates. Economic depreciation rates are calculated on the basis of the observed average market prices that depreciated assets at different ages actually sell for. Sometimes statisticians try to estimate the average "service lives" of fixed assets as a basis for calculating depreciation and scrap values, based on the observed length of time that fixed assets are actually held and used by their owners.
