PPP and CPI - Combining?

Hi!

I would like to know if it's possible to use both the purchasing power parities (for the comparison between countries) and the consumer price index (for the comparison of one country over time) ?


I invastigate wages in europe and I use pooled panel regression models. For this purpose i have to weight hourly wages by both cross-country and time differences in purchasing power.


I hope someone can help me!
Best Regards
