日本経済学会 - Japanese Economic Association
The JEA-Nakahara Price was established in 1995 and is funded by a donation from Mr. Nobuyuki Nakahara. The prize was established to honour researchers in economics under the age of 45 who have produced internationally recognized research.
It is my great pleasure to announce that the 2006 JEA-Nakahara Prize has been awarded to Professor Yuichi Kitamura of Yale University. Born in 1963, Professor Kitamura gained his BA from the University of Tokyo and his Ph.D. through the Department of Economics, Yale University. Currently he is Professor of Economics, Yale University.
Professor Kitamura has made a significant contribution to the theory of econometrics - in particular to the nonparametric likelihood approach?which has been different from the standard methods explained in textbooks and quite new in that sense (see Kitamura, 2006). In his 2001 paper, in Econometrica, and the 1997 joint paper with Professor Stutzer, also in Econometrica, he has shown that the nonparametric likelihood approach has the optimal properties for estimation and testing in the econometric models. Also his 1997 paper in the Annals of Statistics has shown that the nonparametric likelihood estimation can be generalized to the weakly dependent case; this was a significant contribution to the empirical likelihood method following the line initiated by A. Owen in the statistics literature. Professor Kitamura has also investigated the conditional moment restriction problem that has been usually dealt with the generalized moments method (GMM) and its variants in econometrics (see Kitamura et al., 2004 and Tripathi and Kitamura, 2003). Due to the recent works of Professor Kitamura and some other researchers, the nonparametric likelihood approach has been a major competitor to more traditional methods including the GMM. He has been changing the very fundamentals of econometric methods and will make a significant contribution with possible econometric applications.
