學(xué)術(shù)講座: Uncertain Technology 題目:不確定生產(chǎn)率 時(shí)間:2017年5月26日中午12:20 地點(diǎn):博學(xué)925 Abstract: We develop a general equilibrium business cycle model with imperfectly observed neutral and investment-specific technology shocks. The model response to neutral technology shocks is similar to the response in an environment with perfect information. However the response to an investment-specific shock is more persistent and depends on the distance between agent expectations and actual values at the time of impact. An erroneous signal about technology, a "noise shock", also alters agent behavior persistently, even when the underlying fundamentals governing the economy are unchanged, and even when the noise is not persistent. 摘要:我們創(chuàng)建和研究了一個(gè)具有不完全信息的一般均衡商業(yè)周期模型。在這個(gè)模型中,經(jīng)濟(jì)參與者觀察不到投資型生產(chǎn)率和全要素生產(chǎn)率的變化。我們用美國(guó)宏觀數(shù)據(jù)估計(jì)模型中的參數(shù)。通過(guò)模擬分析,我們發(fā)現(xiàn)經(jīng)濟(jì)對(duì)全要素生產(chǎn)率變化的反應(yīng)類(lèi)似在具有完美信息的環(huán)境中的反應(yīng)。然而,對(duì)投資型生產(chǎn)率的沖擊反應(yīng)更加持久,也取決于期望與實(shí)際之間的距離。關(guān)于不完全信息的錯(cuò)誤信號(hào)可以改變經(jīng)濟(jì)參與者的行為,即使生產(chǎn)率沒(méi)有變化或者錯(cuò)誤信號(hào)并不持久。 演講人簡(jiǎn)介: 馬笑寒現(xiàn)任德州理工大學(xué)經(jīng)濟(jì)學(xué)助理教授。他在北京大學(xué)獲得法語(yǔ)和經(jīng)濟(jì)學(xué)雙學(xué)位學(xué)士,在華盛頓州立大學(xué)獲得應(yīng)用經(jīng)濟(jì)學(xué)碩士,在喬治華盛頓大學(xué)獲得經(jīng)濟(jì)學(xué)博士。他主要研究不確定經(jīng)濟(jì)環(huán)境對(duì)商業(yè)周期和政策決策的影響。他還研究研究國(guó)際貿(mào)易,產(chǎn)業(yè)轉(zhuǎn)型與經(jīng)濟(jì)增長(zhǎng)之間的關(guān)系。他曾在國(guó)際貨幣基金組織和喬治華盛頓大學(xué)國(guó)際經(jīng)濟(jì)政策研究所擔(dān)任研究助理。
