 Interview with Professor Yongmiao HONG

I. Welcome and Opening Remarks
Anny:  Good afternoon.  As winter comes round, many memories, hopes and aspirations burgeon in our hearts when we join this grand academic conference, which is so inspiriting and so charged with profound educational meaning.
The distinguished guest who will address us today is Professor Yongmiao Hong. Professor Yongmiao Hong is a great econometrician of our time. He is best known, perhaps, for his achievements in economics research and especially for the expertise that concerns us here this afternoon, which is econometrics. Apart from his numerous econometrics publications in high ranking journals, his dedications to education win him respect worldwide.
Professor Hong, could you tell us something about how you came to study economics and what attracted you about econometrics?

这里对华人的几个搞计量的经济学学家做一个简短的评论。

在世界上,华人现在做计量得很多,按照名气排名的话,Chen Xiaohong (Yale & NYU), Fan jianqing(Princeton)(统计+计量),Lee Lungei(Ohio State), Hong yongmiao(Cornell),Li Qi(TAMU), Ai Chunyong(Florida), Bai Jushan(NYU), Fan Yanqing(Vandbilt), Xiao Zhijie(BU), 老一辈的还有 Chow G. (Princeton)(邹至庄), 刁锦寰(Wiconsin)等。都是正教授。

从数量上讲,洪永淼的贡献很多。另外一个很牛的人就是 Li Qi. 他们和很多在美国的华人经济学家一样,写了很多文章。在很多顶尖杂志上灌了很多水。但是很多是修修补补,我们称为Brick-Mover, 贡献很marginal.

但是美国这个社会和中国不一样,质量重于数量。

最典型的是陈晓红 (Yale and NYU),一个矮小的中国女人,就靠两篇论文(证明了GMM在SEIVE中得一致性,效率性和Normality )。刚刚成了econometric society的 fellow.这是大陆出生的经济学家中的第一个。econometric society的 fellow是每一个经济学家的梦想,估计是除了 nobel 炸药奖之后的荣誉了。可以这么讲,要获得炸药奖,首先必须是econometric society的 fellow。要不,根本没有机会获得提名。
感谢洪永淼教授为中国经济学做的贡献,我们也希望洪永淼教授能够成为econometric society的 fellow。

II. Keynote Address by Professor Yongmiao Hong

Yongmiao Hong:Good afternoon, everyone!

It is a great honor to be invited to attend this online forum on RenDa BBS, sharing views on econometrics and economics education in China. First of all, I’d like to thank RenDa BBS and the managers of this forum to provide such an excellent opportunity. In what follows, I will talk about some recent developments in econometrics, particularly time series econometrics. Then I will introduce financial econometrics, a relatively new field emerging from the application of econometrics to finance. I will discuss econometrics education and research in China, also and internationalization of Chinese economics.

Before I discuss the aforementioned issues, let me first introduce my academic career and research. I was born in a village near Xiamen Island where I received my primary and high school education. Because my physics exam earned the highest score among all subjects in my national college entrance examination, I chose Physics as a major at Xiamen University (XMU). This choice was not rational from today’s point of view (except for maximizing the chance to be admitted), because I had no idea about my research and career interest in the future. I received a BA in Physics in 1985, and then was admitted to the MS program in Physics at XMU. I completed all required core MS courses in Physics, I found that Physics was not my interest, and so transferred in 1986 to Economics Training Center at RenDa, which was initiated by Professor Gregory Chow and sponsored by Ford Foundation. I have been most grateful to Professor Chow and Professor Gejia Shu, the first dean of School of Economics at XMU, who allowed XMU students in science majors to apply for the Ford program. I’m also most grateful to RenDa, where I started my economic career.


During one year study at RenDa, I learnt intermediate macroeconomics, intermediate microeconomics, public economics, law and economics, development economics, decision making under uncertainty, taught by American professors, and socialist economy, taught by RenDa professors. One year later, I went back to XMU to write my MA thesis, which compared Konai’s Economics of Shortage (a theory for a socialist economy) and the disequilibrium model in a capitalist market economy (e.g., Benassy). Upon earning an MA in Economics in 1988, I was admitted to the PHD program in Department of Economics, University of California at San Diego (UCSD), majoring in econometric theory. During this period, I also did an empirical panel data project on economic reforms of Chinese state owned enterprises with professors at UCSD. I learnt a great deal about the application of econometrics and Chinese economy by dealing with real data. After receiving a PHD in 1993, I became an assistant professor in Department of Economics at Cornell, a tenured associate professor in 1998, and a full professor in 2001.

My doctoral dissertation was on model specification testing using nonparametric series regressions in a cross-sectional context. The basic idea is to compare the sums of squared residuals between a parametric regression model and a nonparametric series regression model. The sum of squared residuals of the former is close to that of the latter when the former is correctly specified, but becomes larger when it is misspecified. This is essentially a generalized F-test with a large number of degrees of freedom. I derived the asymptotic distribution of the proposed test statistics.

At Cornell, I attempted to apply the nonparametric method to a time series context, and I found that it has been used to estimate the spectral density function of a time series. The spectral density function and the autocovariance function are two basic analytic tools in time series analysis. I developed tests for serial correlation of unknown form in the residuals of a time series regression model. The idea is to use the nonparametric method to estimate the spectral density function of an estimated residual series and checks whether it looks like a “flat spectrum”. If there exists no serial correlation (i.e., the residuals are a white noise process), the spectral density function is a constant (so is flat) as a function of frequency.

In working on testing serial correlation, I received a critism that the spectral density function cannot capture nonlinear serial dependence such as ARCH effects (i.e., positive autocorrelations in squared residuals). Nonlinear dependence is an important feature in macroeconomies and financial markets. In response to this critism, I came up with a solution. The basic idea is to first transform the original time series data via a nonlinear function and then inspect the spectral density of the transformed time series. This new approach can capture nonlinear serial dependence such as ARCH effects, and it is termed as the generalized spectral analysis.

Because subtle nonlinear dependent features often occur in financial markets, a natural application of nonparametric methods and generalized spectrum is to financial markets and financial time series data. Thus, I became interested in financial econometrics. I developed econometric tests for market efficiency, Granger causality in risk, and continuous-time models. I also did some work in empirical finance, including return predictability in stock markets and foreign exchange markets, and interest rate term structure dynamics.

In 2002, I was appointed as a special-term professor in Department of Economics, School of Economics and Management, Tsinghua University. Since 2005, I have been helping running Wang Yanan Institute for Studies in Economics (WISE) at XMU. My involvement in Tsinghua University and particularly in XMU has crowded out much of my academic research time, but it is a very interesting and valuable experience as I can get a better understanding of Chinese economics education and research. I’d be happy to share with you my observations and ideas on Chinese economics education and research, particularly econometrics education and research.
