Interpretation of interaction variable in PPML

Dear all,

I would like to know if I can interpret interaction variables in PPML the same way as in OLS.

In PPML the coefficients of any independent variables entered in logarithms can still be interpreted as simple elasticities, right? Does that also mean that I can interpret interaction effects the same way as in OLS or do I have to calculate them in a different way?

Thanks very much in advance!
