Academic & Professional Qualification
  • Ph.D., M.A., Princeton University
  • B.S., Wuhan University

Prof. Yulei LUO graduated from Wuhan University in 1997 with B.S. in Electronics and Information System, and obtained his Ph.D. in Economics from Princeton University in 2005.  He joined the Faculty of Business and Economics (now HKU Business School) in 2006 and became Associate Professor in 2012.

Yulei’s research interests are in macroeconomics, asset pricing, and international finance. He has papers published in academic journals including Management Science,Journal of Economic Theory, Journal of International Economics, American Economic Journal: Macroeconomics, Journal of the European Economic Association, European Economic Review, Review of Economic Dynamics, Journal of Money, Credit and Banking, Journal of Economic Dynamics and Control, Economic Inquiry, and Macroeconomic Dynamics.

Yulei has done some work on sticky information, robustness, and aggregate fluctuations.  He has also studied the implications of idiosyncratic shocks and incomplete markets on wealth inequality and aggregate dynamics.  His current research interests are about optimal consumption-savings and portfolio rules under induced uncertainty, and their implications for asset pricing, business cycles, and welfare.

Ambiguity, Low Risk-Free Rates, and Consumption Inequality

Macroeconomists failed to predict the Great Recession, suggesting that the existing macroeconomic models may have been misspecified. Bearing in mind this potential misspecification or “model uncertainty,” how do agents’ optimal decisions change? Furthermore, how large are the welfare costs of model misspecification? To shed light on these questions, we develop a tractable continuous-time general equilibrium model to show that a fear of model misspecification reduces both the equilibrium interest rate and the relative inequality of consumption to income, making the model’s predictions closer to the data. Our quantitative analysis shows that the welfare costs of model uncertainty are sizable.
