The research opportunities and experiences at AMU have turned out to be both challenging and constructive. We say “challenging” in the sense that we have never encountered with economic theories as seriously as here at AMU. A new field of research has been opened up. We say “constructive” in the sense that while learning from dialogue with economists, we find that there is something that we can contribute to intellectual development in general and LIBEAC in particular by drawing out the economic consequences of the communicative norm of reciprocity as clearly as possible. We feel that this is probably what we can make as our own genuinely creative work. For this continuing work, we plan to come to AMU again next year, hopefully from April to June, 2015
