The economics of transformation from even-aged to uneven-aged forestryfitability. Single-tree selection offers a logical possibility of increased long-term profit, but the lead time makes transformation unprofitable except at low discount rates.

A multi-output restricted profit function for Norwegian sawmillings, probably due to different export and import opportunities. Non-jointness was rejected for inputs and for outputs. Separability tests indicated that some further aggregation could have been possible. There were decreasing returns to size and negative technical change for the average sawmill in the short run.
