新结构经济学Workshop
时间：2017年6月2日下午15:30-17:00
地点：朗润园万众楼小教室
主持人：王勇、王歆、徐佳君
主讲人：Roberto Samaniego (George Washington University)Topic: Uncertain Technology
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.
Speaker:
Roberto Samaniego is Professor of Economics and International Affairs. He received his PhD in Economics from the University of Pennsylvania in 2001, joining the faculty of the George Washington University in September of that year. He also holds a BA in Economics from Princeton University. Professor Samaniego has published articles in a number of leading economics journals, including the American Economic Review, the Journal of Monetary Economics, the Journal of Money, Credit and Banking and the Journal of Economic Growth. His primary professional interests are in the areas of macroeconomics and economic growth. He has focused on understanding the relationship between technical progress, entrepreneurship and institutions.
