Simon Wren-Lewis forcefully argues that austerity is a product of political opportunism on the right.
" ... Austerity is nearly always unnecessary,...
[Which] makes the question of why policy makers made the mistake all the more pertinent....
The set of arguments that I think have more force, and which make up the general theory of the title, reflect political opportunism on the political right which is dominated by a ‘small state’ ideology. It is opportunism because it chose to ignore the (long understood) macroeconomics, and instead appeal to arguments based on equating governments to households, at a time when many households were in the process of reducing debt or saving more. But this explanation raises another question in turn: how was the economics known since Keynes lost to simplistic household analogies.
This question can be put another way. Why was this opportunism so evident in this recession, but not in earlier economic downturns? There are a number of reasons for this, which I also discuss here, but one that I think is important in Europe is the spread of central bank independence, coupled with a phobia that European central bank governors have about fiscal dominance. In the UK, for example, the Bank of England played a key role in 2010 in convincing policymakers and the media that we needed immediate and aggressive fiscal consolidation. Keynesian demand management has been entrusted to institutions whose leaders (but not those who work for them) threw away the manual. But as Ben Bernanke showed, it does not have to be this way.
If my analysis is right, it means that we cannot be complacent that when the next liquidity trap recession hits the austerity mistake will not be made again. Indeed it may be even more likely to happen, as austerity has in many cases been successful in reducing the size of the state. My paper does not explore how to avoid future austerity, but it hopefully lays the groundwork for that discussion."
I also liked the Obama quote he opens with:
“If we cannot puncture some of the mythology around austerity … then we are doomed to keep on making more and more mistakes.”
