The Case of the Missing Trade and other Mysteries:
Comment
forthcoming in the American Economic Review
The publication process of necessity rations the amount
of information that can be included in a journal article. I have
assembled this Web site as an "appendix" to my comment on Daniel Trefler's
important American Economic Review piece of December 1995.
You should find sufficient information here to duplicate all of my calculations.
You'll also find working papers and appendices that lay out the theoretical
bases of the estimating equations. If you have any comments on the
analysis presented here, please contact
me with your thoughts.

Daniel Trefler originally provided his data to me in SAS format, and these
files are extensions and variations of that original program. Thanks
to Professor Trefler for agreeing to publish the data and programs in this
way.
