“Land Sparing” in a von Thünen Framework: Theory and Evidence from Brazil
利用巴西朗多尼亚州家庭地块的面板数据，检验了冯·杜能框架下“土地节约”假说，发现靠近市场的家庭更可能因牛肉和牛奶需求上升而节约牧场用地、保护森林，但初始森林禀赋较多反而导致更多砍伐。
This paper evaluates microscale evidence for “land sparing” in a von Thünen framework. A panel dataset of household lots in Rondônia, Brazil is used to test the hypothesis that the closer a household is to market the more likely it will adopt land-sparing patterns of cattle production in response to rising demand for beef and milk. Results from a fixed effects model suggest that, consistent with theory, pasture area declines and forest is spared in lots located closer to market. Other results differ, however, depending on forest type and commodity. Greater initial endowments of forest are associated with more deforestation. <i></i>
