小弟最近翻译一篇英文文献，叵耐理论功底欠缺，遇到很多阻力。在此请教高人。在后凯恩斯主义流派中提到关于利率的相关观点，分别是
the activist and the parking-it approaches. 我不明其意，有谁可以告诉我这是什么意思并且相关理论（中文的）哪里可以找到？
原文上下文：


As discussed previously, the first element of the Post Keynesian theory of the transmission mechanism rests on the endogenous nature of credit-money and the role banks play. This argument requires very little discussion, as there is considerable consensus in Post Keynesian circles on this matter. However, the second component—the role played by income distribution—requires a more detailed discussion as it necessitates consideration of the two distinct approaches to interest rate policy in Post Keynesian theory: the activist and the parking-it approaches.
