Advances in Mathematical Economics Volume 9

A lot of economic problems can formulated as constrained optimizations and equilibration of their solutions. Various mathematical theories have been supplying economists with indispensable machineries for these problems arising in economic theory. Conversely, mathematicians have been stimulated by various mathematical difficulties raised by economic theories. The series is designed to bring together those mathematicians who were seriously interested in getting new challenging stimuli from economic theories with those economists who are seeking for effective mathematical tools for their researchers.

Planned to publish this series once a year under the auspices of the Reserch Center of Mathematical Economics (Tokyo) Designed to bring together those mathematicians who are seriously interested in obtaining new challenging stimuli from economic theories and those economists who are seeking effective mathematical tools for their research Authors are asked to develop their original results as fully as possible and also to give a clear-cut expository overview of the problem under discussion Consequently, this series will also invite articles which might be considered too long for publication in journals
