st: Wald tests of equality of coefficients on opposite sides of the land lease markets

[Jeetendra Aryal <jeetendra.aryal@umb.no>]

Dear, 
 
I am working with a dataset in which net land leased in (NLI) is the dependent variable. I ran tobit models for the two sides of the land leased marekt as follows:
1) For nonparticipant (NLI=0) and leasing in (NLI>0) households, say equation 1
2) For nonparticipant (NLI=0) and leasing out (NLI<0) households, say equation 2
 
Now I want to run  Wald tests of equality of coefficients on opposite sides of the land lease markets (i .e. equation 1 and equation 2). 
Any suggestion to run this is appreciated.
 
regards,
Jeetendra
