Book Description
This paper derives the optimal harvesting policy for a renewable natural resource using a real-option model. The harvesting policy is illustrated using the well-known “tree-cutting” or “optimal rotation” problem from Forest Economics. We show how to identify the optimal tree size at which to harvest (or the optimal harvesting trigger), and also the resulting expected rotation period. The optimal trigger depends on (i) the growth dynamics of the tree, (ii) the interest rate, (iii) the harvesting cost, and (iv) size of the replacement seedling. With reasonable input parameters, it is shown that tree size must increase to 41⁄2 times the original size before it is optimal to harvest it, which gives an expected rotation period of 51 years. The model is flexible enough to accommodate various adjustments if necessary.

Book Description
As society becomes stressed by economic and population pressures, in turn, nature's renewable resources become stressed by harvesting pressures. For our own survival and euphoria, it is paramount that such resources remain as their name implies and not be driven to extinction through short term programs of over exploitation. Consideration of the harvesting of renewable resources leads to a simple question that was the theme of the workshop and is the focus of these proceedings: SUPPoRe you are assigned the role of manager for a specific renewable resource eco system. How would you decide on harvesting policies so that the system can be exploited economically yet at the same time maintain the integrity of the system? This, of course, is a loaded question. First of all, it is not clear that there is ever anyone single decision maker who is able to set the rules for all of the harvesters in an exploited ecosystem. The political process is complicated and to some extent unpredictable. This aspect of the question is recognized to be important, but could not be addressed here. Assuming then that someone really is in charge, what would be involved in the * decision making process? As Clark points out, "there is no alternative but first to model the system. " We agree. However, if the original question was loaded, modeling is the adulterate.

Book Description
The objective of this thesis is twofold. First, it examines optimal investment problems arising in renewable resource sectors such as forestry where important externalities are attached to the growing stock, and where investment in the resource (the biomass) and application of capital and labour (the harvesting capacity) must be considered simultaneously. Second, a general framework for empirical analysis is developed. to analyze logging production under profit maximization, and when externalities are attached to the standing forest. Taxation regimes and quantitative control policies to correct for market failure in forestry are examined. The analytical solution is characterized by dynamic bioeconomic golden rule equations. A generalized, dynamic Faustmann-Ohlin rule is derived for the case when more than one type of harvesting method is used. This is a new theoretical feature of the approach explicated here. obtained of optimal harvest rates, stock levels, site values and other information of relevance to forest policy. Efficiency implications of current forestry legislation and taxation are assessed. The utility of the estimated model for practical forest management is also demonstrated. Although applied to forestry, the approach is readily amendable to renewable management in general. efficient forest management does not appear to be in conflict with the intent of Swedish forestry legislation.
