There are two files associated with this article.  The first, called
WELFARE.PRG replicates the GAUSS program shown in Table A1.  This is
the program that has been used in this article;  it calculates the
compensating variation and standard error for whatever demand function
that is specified.  In the case of Table A1, this is the McKenzie Pearce
example shown in Table 2.

The second program, VARTIA.PRG, replicates Table A2.

Both programs run under most versions of GAUSS, as is.  Copy the program
to some directory eg c:\WELFARE, then from the GAUSS prompt type
RUN c:\welfare\welfare.prg
in the normal way.
