I discussed in a previous post about the failure of austerity measures in Portugal. Here, I would like to take a few steps back and look better at the theoretical foundations of austerity. Without being a theoretical presentation of austerity, this post rather discusses the empirical evidences regarding the effects of austerity measures.
To many, this is not news. However, given the persistence of IMF and other international institutions to insist with new austerity measures, it is still surprising.
There is a general agreement that the mainstream macroeconomics has largely failed to predict or correctly estimate the last economic and financial crisis, see the introduction here on the website of the Institute for New Economic Thinking. This failure has motivated more than ever different heterodox approaches to macroeconomics.
