Of course you can. That is what government statistics and academic studies are for. But the source here, I believe was from an executive of a pasta factory. It would be surprising to me if essentially all the pasta in Italy was made by one producer and sold at one price, such that you could talk about trends in fractions of a Euro based on one interview like this. I'm used to staples being sold at different price points within a grocery store and across different stores or different communities. Not a range of 40-80% like your sample numbers, but 300% or more.
