Editor's Foreword

This issue is dedicated to the memory of Tapan Biswas,  who passed away on July 3, 2010. Tapan was a founding associate editor of the Review  of Economic Analysis and a great colleague of many of people involved with the journal. The issue begins with In Memoriam by Gianluigi Pelloni, followed by a previously unpublished paper, joint with Taradas Bandyopadhyay on which Tapan was working at the time of his untimely death and by Tapan’s best published papers. I would like to thank all publishers of Tapan’s work for agreeing to republish his papers. The copyright belongs to the original publishers and no part of this issue, except for the first paper, can be reproduced in any form without their permission. Jerzy (Jurek) Konieczny
