日本経済学会 - Japanese Economic Association
The JEA-Nakahara Prize was initiated in 1995 and is funded by a donation from Mr Nobuyuki Nakahara. The prize was established to honour young economists under the age of 45 who have achieved internationally recognized research.
It is my pleasure to announce that the 2000 JEA Nakahara Prize has been awarded to Professor Kazuya Kamiya. Born in 1957, Kamiya took his BA from Kyoto University in 1981 and his PhD from Yale University in 1986. At present he is Professor of Economics at the University of Tokyo.
Professsor Kamiya has made several contributions in the areas of general equilibrium theory and mathematical programming. He showed that, if firms with non-convex technologies are regulated to follow a certain pricing rule, then under mild conditions there exists an equilibrium, and he presented a nonlinear pricing rule which always leads to Pareto-efficient allocations in an economy with non-convex technologies.
Kamiya presented a decomposition algorithm that is generically applicable to systems of highly nonlinear equations with a special structure. He also constructed a differential equation which always converges to an equilibrium from almost every interior starting point, without imposing an additional assumption that is necessary to guarantee the convergence of Walras's tatonnement process.
Professor Kamiya's major works include:
