Here are the slides from my talk regarding the state aid cases at a conference in Luxembourg University last week. (I couldn't post them while abroad due to an error that I needed to fix from back home.)
I'll be discussing the state aid cases again later this month, at an Oxford Centre for Business Taxation annual conference, to be held on June 30. The conference, entitled "Escalating Uncertainty and Competition in Business Taxation, will follow immediately on the heels of their 2017 Academic Symposium, at which I'll be a discussant (re. an Ed Kleinbard paper discussing his business tax reform plan). But the Oxford state aid slides will be quite different from the ones I've just posted, reflecting the different setting.
