THE DEVELOPING FRAMEWORK FOR THE ECONOMIC EVALUATION OF FORESTRY IN THE UNITED KINGDOM — A COMMENT
评论了Kula的贴现消费流方法在林业投资评价中的应用，指出该方法虽比净现值法更有利，但可能导致代际不公平，建议降低社会贴现率至零以实现公平。
The application of Kula's sum of discounted consumption flows method to forestry investment gives a more favourable result than NPV, but leads to some curious consequences. In particular, the immediate future generation may not be provided with a timber resource by the present generation, while being expected to provide such a resource for its own successors. The method does not in fact treat future generations equitably: downward revision of the social discount rate, possibly to zero, is a better means of achieving this objective.
