Effect of Carbon Taxes and Subsidies on Optimal Forest Rotation Age and Supply of Carbon Services
研究碳税和补贴如何影响森林最优轮伐期及碳储存，发现某些税制下不砍伐可能更优，且考虑碳吸收外部收益后轮伐期略长于财务最优。
Abstract Carbon taxes and subsidies will affect the optimal forest rotation and, consequently, the carbon stored in forests. Unlike the Hartman rotation, where externality benefits are a function of the volume of timber growing on a site at any time, carbon benefits are a function of the change in biomass. Theoretical and empirical results (for coastal British Columbia and northern Alberta) indicate that, under some tax regimes, it may be socially optimal never to harvest the trees. In general, inclusion of the external benefits from carbon uptake results in rotation ages only a bit longer than the financial (Faustmann) rotation age.
