我们提出了一个框架，在农业生产、可持续森林管理和以非法采伐形式进行的不可持续森林开发之间进行内生性土地分配，以探索产权不安全时的森林砍伐以及农业和木材供应。可持续管理的林地被没收的风险以及边境原生林地的非法采伐活动产生了产权的不确定性。研究表明，没收风险会增加土地转为农业和非法采伐，从而加剧森林砍伐。与目前的观点相反，我们发现木材价格上涨并不一定会导致可持续林业用地的增加，因为价格上涨会刺激非法采伐活动。加强监测和加强执法，减少非法采伐，从而减少森林砍伐。不可持续的林业做法导致没收风险减少了木材供应，而木材价格对木材供应的影响则不明确。
We propose a framework with endogenous allocation of land between agricultural production, sustainable forest management, and unsustainable forest exploitation in the form of illegal logging to explore deforestation and agricultural and timber supplies when property rights are insecure. Uncertainty over property rights arises through risk of confiscation on sustainably-managed forest land, and through illegal logging activities on frontier native forest land. Confiscation risk is shown to increase deforestation by increasing both land conversion to agriculture and illegal logging. Contrary to current wisdom, we find that higher timber prices do not necessarily lead to an increase in the land used for sustainable forestry, because higher prices stimulate illegal logging activity. Increased monitoring and stronger enforcement reduce illegal logging, and thus deforestation. Confiscation risk decreases timber supply from unsustainable forestry practices while the affect of timber price on timber supply is ambiguous.
