GUISE 发表于 2025-3-22 16:44:34

The economics of transformation from even-aged to uneven-aged forestryis. Economic justifications such as improving profitability, or gaining early, well-distributed or flexible revenue are spurious. Falling timber prices do justify shifting to lower-input silviculture. Even without firm data, rational decision making is aided by knowledge of trade-offs between extra

Re-examining the theories supporting the so-called Faustmann formulann or land expectation value formula (LEV). Several conditions have produced the co-existence of different LEV formulas, which generate different land asset values for the same forest management problem. This problem was probably generated given different economic traditions, forest management conce

An econometric analysis of differences in stumpage values using micro-level harvesting datasize and decomposes differences between regions. Due to the thick-tailed distribution of the data and the presence of heteroscedasticity, the paper gives a comparison of ordinary least squares regression with an iterative weighted least squares (IWLS) estimator and a multiplicative heteroscedastic m
