ABSTRACT
I would like to thank Guido Erreygers, Albert Jolink, Vincent Tarascio and participants at the 1998 European Conference on the History of Economics (‘Exchange at the Boundaries: Crossing Borders in the History of Economics’) for helpful discussion. I am also indebted to three anonymous referees for their suggestions. I am grateful to Eric Nicander, of Lund University Library, for helping me with the Wicksell Archives. Financial support from CNPq (Brazilian Research Council) is gratefully acknowledged.
