NBER Working Paper No. 15926
---- Acknowledgements ----
This paper is a revision of a long-stalled earlier version circulated and presented in 2006 and 2007 under the title "Expansion of trade at the extensive margin: welfare and trade-volume consequences". The paper was presented at the Athens ETSG and at CESifo Munich in September 2007 and in a couple of other places I can't remember. I appreciate comments received then and added comments, suggestions and references are most welcome now.
