中國人民大學劉凱老師在中國人民大學宏觀經(jīng)濟論壇上作了一場題為“自動穩(wěn)定器在美國經(jīng)濟周期中的作用”的講座，中國人民大學經(jīng)濟學院開設的有政治經(jīng)濟學、西方經(jīng)濟學、經(jīng)濟思想史、世界經(jīng)濟、國際貿易學、經(jīng)濟史、國民經(jīng)濟學、網(wǎng)絡經(jīng)濟學、企業(yè)經(jīng)濟學、區(qū)域經(jīng)濟學、數(shù)量經(jīng)濟學、國防經(jīng)濟、城市經(jīng)濟學、國際商務等碩士學位專業(yè)，講座的主要內容是：

　　大多數(shù)國家都在被部分意在平抑經(jīng)濟波動的稅收和轉移系統(tǒng)自動規(guī)則。本文衡量他們如何有效。我們合并消費和不平等與名義剛性和經(jīng)濟周期的新凱恩斯模型的標準不完全，市場模式，這包括大部分的主要潛在穩(wěn)定的美國經(jīng)濟數(shù)據(jù)。我們發(fā)現(xiàn)，傳統(tǒng)的說法，穩(wěn)定的可支配收入將穩(wěn)定總需求起到的穩(wěn)定劑的有效性的作用微乎其微，而影響不平等和社會保險稅和轉移計劃可以對總的波動有很大的影響。根據(jù)我們的模型，擴大安全網(wǎng)方案，像糧票，具有增強的穩(wěn)定劑的效力最大潛力。

　　人大宏觀經(jīng)濟學研討會(Macro Workshop)旨在追蹤宏觀經(jīng)濟學國際最新進展，倡導構建符合國情的動態(tài)優(yōu)化模型，并使用計算機模擬研究經(jīng)濟增長、收入分配和宏觀政策等中國宏觀經(jīng)濟重大問題。

　　原文：Most countries have automatic rules in their tax-and-transfer systems that are partly intended to stabilize economic fluctuations. This paper measures how effective they are. We merges the standard incomplete-markets model of consumption and inequality with the new Keynesian model of nominal rigidities and business cycles, and that includes most of the main potential stabilizers in the U.S. data. We find that the conventional argument that stabilizing disposable income will stabilize aggregate demand plays a negligible role on the effectiveness of the stabilizers, whereas tax-and-transfer programs that affect inequality and social insurance can have a large effect on aggregate volatility. According to our model, expanding safety-net programs, like food stamps, has the largest potential to enhance the effectiveness of the stabilizers.
