A classical problem in forestry is the determination of the optimal rotation. This problem was solved during the 19th century, by German forest mathematicians. Martin Faustmann deserves some of the fame. However, he did not explicitly derive the conditions for an optimal solution. His contender...

This paper examines the effect of risk aversion on the optimal rotation age when the stumpage price is stochastic. Using a mean-variance approach, we show that the optimal rotation age under risk aversion may be lower than, equal to, or higher than the corresponding optimal rotation age under...

Previous studies have reported significant gains from adaptive harvest strategies when future timber prices are uncertain. For the final harvest decision in even-aged stand management, the adaptive strategy typically means that a stand is harvested only when the timber price is high, whereas low...

The paper assesses the welfare effects of biotechnological progress, as exemplified by tree improvements, using a partial equilibrium model. Timber demand is assumed to be stochastic and the distributions of the coefficients of the demand function are known. Assuming that timber supply is a...

This paper develops an optimal harvesting model for the wild Atlantic salmon (Salmo salar), where various age classes of the population is included. It is shown that the marginal value-fecundity relationship of the spawning population, comprising young and old fish, is crucial for the optimal...
