Hi,
I can only give you a perspective for Toulouse School of Economics. I am a PhD student there and I did my master 2 Econometrics and Economic Theory (ETE) at TSE as well. TSE is a great school and the only reason you haven't seen it "recognized" in the rankings is that the school is only ten years old. Rankings are usually done with data for the past 5 years and so on and is only updated so often, so when you look up ranking for TSE you will find the rankings for its first 4 years or so. Give it a few more years, and TSE will be appearing in all rankings. The quantity of professors and researchers in economics is amazing and has no comparison. One way you could notice the rising prestige of TSE is to see the amount of papers published by our faculty. Furthermore, the school is good at helping you find internship and jobs afterwards and during your studies.
Good luck with your studies!
