Intertemporal Equity and Hartwick's Rule in an Exhaustible Resource Model*
在标准可耗竭资源模型中，已知若竞争路径满足哈特威克规则（将可耗竭资源的租金投资于可再生产资本），则消费水平恒定，实现代际公平。本文证明其逆命题：若竞争路径是公平的，则必满足哈特威克规则。
Abstract In a standard exhaustible resource model, it is known that if, along a competitive path, investment in the augmentable capital good equals the rents on the exhaustible resource (known as Hartwick's rule), then the path is equitable in the sense that the consumption level is constant over time. In this paper, we show the converse of this result: if a competitive path is equitable, then it must satisfy Hartwick's rule.
