Austerity Facts?

Russ Roberts wants the facts:

Which nations in Europe have slashed government spending? I suppose “slash” is an ambiguous term but when you write  that the experiment has been tried, don’t you have to show that spending has at least been cut or reduced, right? Maybe some European states have slashed the growth rate in government spending? Is that what he means? If so, shouldn’t different words be used? And either way, should there be some facts on this “experiment.” The word implies something scientific. But it all appears to be going on in the mind of the writer rather than in the real world

I’d like some facts. I have seen many articles on austerity. I can’t remember seeing any that suggest that government spending in any European country has actually fallen. Yes, there is talk of spending cuts or cuts in growth rates. But I’d like to see the data that shows the cuts have actually been implemented.

Me too. Where should I look?
