Tb168: Time-Series Analysis Of Maine Stumpage Prices, John B. Lindahl, Andrew J. Plantinga
Technical Bulletins
The authors of this bulletin analyze price series for stumpage in Maine. For each available species and product group (sawlogs, pulpwood), they test for stationarity and fit autoregressive integrated moving average (ARIMA ) models to the data based on preliminary diagnostics. They then perform in-sample and out-of-sample price forecasts. The central objective or this work is to characterize the processes for Maine stumpage prices in order to identify opportunities for using reservation price policies to increase timber and land values. These results are of particular value to nonindustrial timber growers for use in scheduling harvests.

Tb166: Maximum Entropy Estimation Of Land Use Shares And Transitions, Andrew J. Plantinga, Douglas J. Miller
Technical Bulletins
This study presents a methodology for estimating land use shares and transitions. Our approach emphasizes the importance of land quality in determining land use. Land quality is an index of the physical characteristics of land such as soil depth, slope, and water capacity. We develop a procedure for recovering the probability that land of a given quality is put t o a particular use. In addition, we identify the probability that land shifts from one use to another.
