RT Journal Article SR Electronic T1 Does Money Grow on Trees? The Diversification Properties of U.S. Timberland Investments JF Land Economics JO Land Econ FD University of Wisconsin Press SP 514 OP 529 DO 10.3368/le.86.3.514 VO 86 IS 3 A1 Bert Scholtens A1 Laura Spierdijk YR 2010 UL http://le.uwpress.org/content/86/3/514.abstract AB This paper quantifies the diversification potential of timberland investments in a mean-variance framework. The starting point is a broad set of benchmark assets represented by various indexes. Including publicly traded timberland investments in the portfolio does not significantly increase mean-variance efficiency. At first sight, U.S. private equity timberland seems to improve the mean-variance frontier, even if the portfolio already contains a forestry and paper equity index. However, after removing the appraisal smoothing bias from the raw timberland data, there is much less evidence that private equity timberland investments increase mean-variance efficiency. (JEL C14)
