Simon Wren-Lewis says:
Corbyn, QE and financial interests: ... I want to talk about Quantitative Easing (QE). The basic idea behind QE is that by buying long term assets at a time when their price is high (interest rates are low) to make their price even higher (interest rates even lower) in the short term, and selling them back later when asset prices are lower (and interest rates higher), you could stimulate additional demand. At first sight it seems not too dissimilar to a central bank’s normal activities in changing short rates. There are however two major differences....
After discussing the differences, and some of the problems with QE, he continues with:
That should mean that everyone is looking around for a better way of doing things when short rates hit their lower bound. Fiscal stimulus is the obvious candidate, but we know the political problems there. ...
In the absence of an appropriate government fiscal policy, I find the logic for helicopter money compelling and the arguments against it pretty weak. But just as with fiscal policy, just because something makes good macroeconomic sense does not mean it will happen. I have always been reluctant to pay too much attention to the distributional impact of monetary policy, because it seemed like one of those occasions when even well meaning attention to distribution can mess up good policy. Yet in terms of the political economy of replacing QE, perhaps we should.
It is more likely than not that QE will lead to central bank losses. ... After all, they are buying high, and selling low. That is integral to the policy. Who gains from these losses. Where does the money permanently created because of these losses go? To the financial sector, and the owners of financial assets (who are selling to the central bank high, and buying back low). In that sense, likely losses on QE will involve a transfer from the public to the financial sector.
If QE was the only means of stabilizing the economy in a liquidity trap, because fiscal policy was out of bounds for political reasons, then so be it. The social benefits would far outweigh any distributional costs, even if the latter could not be undone elsewhere. But if QE is a highly ineffective instrument, and there are better instruments available, you have to ask in whose interest is it that we stick with QE?
