In the second section, we derive the CAPM for rates of change in period-average values of any type of asset, and suggest methods to obtain improved estimates of model parameters from averaged data.
Thus, assumptions about the other components of forest asset value tend to alter only the estimate of the CAPM alpha, and to a good approximation, the CAPM beta can be estimated with rates of change in stumpage price alone (Thomson and Baumgartner 1988).
Annual rates of return for forest assets are calculated from rates of change ([R [bar].
2350 from rates of change in the price of sawtimber stumpage and - 0.
To clarify the empirical implications of the two approaches to measuring the CAPM's explanatory variables, we used first and second calendar year market and risk-free rates of return to estimate the CAPM for rates of change in eleven of the series of annual-average sawtimber stumpage prices analyzed by Redmond and Cubbage (1988): bid prices for Douglas fir, western hemlock, ponderosa pine, southern pine, mixed hardwoods, maple, and oak sold from national forests (Ulrich 1987);(2) and prices for southern pine, ash, gum, and oak sold from private land in Louisiana (Ulrich 1987).
ESTIMATING THE CAPM FROM RATES OF CHANGE IN PERIOD-AVERAGE ASSET VALUES
Procedures to correctly estimate CAPM parameters from rates of change in reported prices of infrequently traded assets utilize both contemporaneous and lagged market and risk-free rates (Scholes and Williams 1977; Dimson 1979).
Rates of change in the index could be used to estimate equation [10] for any value of n because the random error in measuring [R [bar].
