Evaluating some financial uncertainties of tree improvement using the capital asset pricing model and dominance analysis
Although uncertainty considerations are of prime importance in capital budgeting, forestry investments are often evaluated without comparing their uncertainty level with their rates of return. This paper examines some financial uncertainties of a west coast Douglas-fir tree improvement program. Biophysical uncertainties such as amount of genetic gain or uncertainty of site quality are determined by apriori assumption to be nonmarket; thus, use of expected value adjusts for these risks. The market uncertainties of tree improvement are found to be reasonable, vis-à-vis other investments as sensitivity analysis shows that the financial risks were small, or the measured β was low. This paper concludes that the tree improvement investment is worthwhile, considering its risk as well as return.
