International Symposium on Choice,
Rationality and Intergenerational Equity

Sponsored by the Grant in Aid for Specially Promoted Research from Japan Ministry of Education for ``Economic Analysis of Intergenerational Issues'' through the Institute of Economic Research of Hitotsubashi University and by the Global Center of Excellence on "Political Economy of Mechanism Design" through Waseda University

Date and Time: From 2:15pm on Tuesday 9th to 5:15pm on Wednesday 10th of September 2008.
Venue: Room 401 of Building 1 of Waseda University. Here is a railway plan to Waseda University.


The purpose of this symposium is to bring together researchers working in the area of rational choice and intergenerational equity. It is intended to be both intensive and extensive: intensive in that each presenter has enough time to go through some details and the audience has some time to ask questions; and extensive in that the topics to be covered by the presentations range from refinements of the classical impossibility theorems on the evaluation of infinite utility streams to problems arising from the multiplicity of choice criteria.
