It's funny that you ask for case studies, because many people argue that what is happening right now has never happened before.

I'm studying business with a healthy dose of economics, and when we ask Professors, they even don't know what is going on, and everyone who says so is just guessing. IMHO no one knows what's really going on!

We have to just let it play out. If you want to be somewhat prepared be flexible and adapt quickly to new situations as you see them developing. Not very useful and very generic but the only thing you and I can do.
