Climate, Adaptation, and the Value of Forestland: A National Ricardian Analysis of the United States
利用县级林地净收益数据,估计气候对林业影响的里卡多模型,发现到2050年气候变化将增加美国东部中纬度林地的净收益,其中约69%的正效应来自广泛边际适应。
This study estimates an econometric Ricardian model of the effects of climate on forestry using a novel national data set of county-level net economic returns to forestland. Results show that climate change projections to 2050 will increase forest net returns on the middle latitudes of eastern U.S. timberland. We quantify the value of extensive margin adaptation to climate change by separately estimating climate's effect on 11 distinct forest types. We find that approximately 69% of the positive climate change effect on eastern U.S. forestry arises from the value of extensive margin adaptation. Climate change impacts in the western United States are inconclusive.
