Why don't you simply construct a 95% confidence interval around the tau
estimate and check if estimates overlap? STATA reports the ASE for tau
with the tab y x, all command.

Warning: overlapping confidence intervals do not necessarily mean that the two are not significantly different.

You need the confidence interval for the difference.
