-dominance- is not found by -findit-. It appears to be a program
produced by World Bank employees. I can see no help file, always a
worrying sign. 

Such an error message might arise because the non-missing values for
your two variables are for quite different observations and the program
expects a different data structure. 
I'm guessing. 

I suggest you contact the authors for support.

I am trying to test dominance of concentration curves using - dominance
- 
command. Say there are 1,000 individuals in the sample and 300 of them
have 
insurance and 700 don't. Concentration curves of their health care 
expenditures are plotted using - glcurve - command. Is it legitimate to 
test dominance of the two curves against each other or do we only test
for 
dominance between two types of variables for the same individual?

When I run the dominance command I get an error saying 'no
observations'. 
Here is what I am doing:

dominance y1 y2 [aw=wt], sortvar(x) rule(both)

where, 
y1= health expenditure of insured
y2=health expenditure of uninsured
x=income variable
