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 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...

A mail survey of NIPF owners in two counties in northern Sweden was conducted to investigate the risk preferences, perceptions of the return and risk of timber investment relative to investment alternatives outside forestry. Our aim was to determine to what extent the NIPF owners’ harvesting...

Woody biomass is the largest source of renewable energy in Europe and the expected increase in demand for wood was the stimulus for writing this paper. We discuss the economic effects of biophysical capacity limits in forest yield from a partial equilibrium perspective. Opportunities to increase...

State-owned forest enterprises (SOFEs) in northeast China and Inner Mongolia play important roles both in timber production and in the maintenance of ecological security. However, since the late 1970s, forest resource and economic crises have seriously restricted these functions. Based on a...

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...
