This is a so-called one-sided test. You can use -test- to test the
two-sided test that the effects of new and old are equal, and than use
the tricks discussed in
<http://www.stata.com/support/faqs/stat/oneside.html> to transform the
results in a one-sided test. An example is given at the bottom of that
FAQ.
Hope this helps,
