This directory contains the data used for the paper
"The Case of the Missing Trade and Other Mysteries"
by Daniel Trefler
November 15, 1994
The files are
1. hov_pub.ssd01
This is a UNIX SAS Version 6.07 file containing the data.
2. hov_pub.xpt
This is a UNIX SAS Version 6.07 export (transport) file. It
was created with the following code:
libname xout sasv5xpt 'hov_pub.xpt';
proc copy in=data out=xout;
select hov_pub;
run;
It be read back into a SAS data set using the following UNIX-based commands:
libname xin sasv5xpt 'hov_pub.xpt';
libname data2 '../junk1';
proc copy in=xin out=data2;
run;
3. hov_pub.dat
This is an ascii version of the data set. It was written with
the following sas PUT statement:
PUT COUNTRY $1-12 FACTOR $14-25 " " AT V Y B YPC;
Thus, the character variable COUNTRY appears in positions 1-12, the
character variables FACTOR appears in positions 14-25, a space appears
in position 26, and the variables AT, V, Y, B, and YPC are formatted
by the SAS "best" format and separated by spaces.
The variables are defined as follows:
at = factor content of trade, F=A*T
v = endowment
y = gdp, world bank, y=p*Q
b = trade balance, world bank b=p*T
ypc = gdp per capita, PWT
country = alphabetic country name
factor = alphabetic factor name
pop = population, wb
4. sample.sas
This is a SAS program that computes some of the statistics used in the
paper as well as in my "International Factor Price Differences:
Leontief was Right!", Journal of Political Economy, Dec. 1993.
5. To check that the data are properly read, the following are sample
statistics
