On Two Elementary Propositions on Customs Unions

We thank Rick Bond, Ian Wooton and seminar participants in Brussels, Copenhagen and Duisburg for comments on a earlier version of this paper. That version was a substantial revision of notes written by Alan Woodland in 1998 in response to a draft of the Kemp-Shimomura paper. We are grateful to Martin Richardson, who kindly provided his correspondence with Kemp on the Kemp-Shimomura paper and have benefited significantly from having access to it. Our interest on these issues started at early 1996 and developed in 1999/2000, when Raimondos-Meller was on leave at the University of Sydney, the hospitality of which is gratefully acknowledged. Woodland gratefully acknowledges the hospitality and support provided by the Economic Policy Research Unit (EPRU) at the University of Copenhagen, where the paper was completed. The research was supported by a grant from the Australian Research Council and by EPRU, whose activities are financed by a grant from the Danish National Research Foundation. Finally, we thank Thalita Marinho for research assistance.
