New Qualitative Properties in the Competitive Nonrenewable Resource Extracting Model of the Firm
用动态原始对偶方法，证明竞争性不可再生资源开采模型存在对称负半定矩阵刻画的一组定性限制，这些新性质超越了霍特林规则，且对称性是模型的基本性质。
Using the dynamic primal-dual methodology, it is shown that a symmetric negative semidefinite matrix characterizes a set of qualitative restrictions implied by the dynamic maximization assertion and the mathematical structure of the model. All of these results are new and show that this model contains many qualitative properties beyond Hotelling's rule. Just as important, symmetry is shown to be a fundamental property of the model, analogous to static models of producer behavior.
