Wood product differentiation in age-structured forestry
We develop the classic market-level, age-structured forest model by extending the description of forestry output from homogenous wood to a set of differentiated outputs such as sawlogs and biofuels. The extension changes several most established results on the long-run sustainable market equilibrium of forestry. We show the existence of an optimal steady state with two (or more) simultaneous rotation periods. This equilibrium yields a smooth timber flow without normal forest structure and thus deviates from existing normal forest results as well as results on equilibrium cycles. We further show that the optimal rotation structure depends on wood product demand and the demand for land outside forestry, another feature that is absent in previous model formulations.
期刊介绍:
Resource and Energy Economics provides a forum for high level economic analysis of utilization and development of the earth natural resources. The subject matter encompasses questions of optimal production and consumption affecting energy, minerals, land, air and water, and includes analysis of firm and industry behavior, environmental issues and public policies. Implications for both developed and developing countries are of concern. The journal publishes high quality papers for an international audience. Innovative energy, resource and environmental analyses, including theoretical models and empirical studies are appropriate for publication in Resource and Energy Economics.
