Dear listers
I'm trying to estimate the Linear Approximate Almost Ideal Demand
System (LA-AIDS). Any resources regarding the estimation of LA-AIDS in
stata? (I've gone through poi's QUAIDS implementation, it didn't help
me). Precisely, the imposition of slutsky symmetry is creating
problems for me.
Furthermore, I studied a document that says that the imposition of or
testing for symmetry restrictions are valid in AIDS models only when
the theoretical price index, instead of the Stone price index, is
used. Thus no need to impose it when using LA-AIDS. Any comments since
no further reference is cited regarding this matter?
