Data and Code for: Correcting the Error in Gamma Discounting

<br>In “Gamma Discounting” Martin L. Weitzman concludes that certainty equivalent discount rates should decline significantly over time. He draws this conclusion from fitting a Gamma distribution to the responses of 2,160 economists asked to give a discount rate estimate and calculating effective discount rates from it. <br><br>The paper to which this dataset pertains replicates Weitzman's calculations on the basis of the data of the above mentoned survey, and repeats the calcualtions with more appropiate methods.<br>

马丁·L·韦茨曼（Martin L. Weitzman）在《Gamma折现》（Gamma Discounting）一文中提出，确定性等价折现率应当随时间推移大幅下降。该结论的推导基于他将伽马分布（Gamma distribution）拟合至2160名受邀给出折现率估值的经济学家的答复数据，并基于此计算得到有效折现率。本数据集所关联的论文基于上述调研数据复刻了韦茨曼的计算过程，并采用更恰当的方法重新开展了相关计算。
