Crucial questions on policy

Despite appearances to the contrary most economists do not spend their time on designing policy. They actually spend their time on the 'basic science' of economics. The answers they come up with allow others to design policy accurately.

In a recent FT article by Lord Skidelsky and Felix Martin suggest a 'Plan C' is needed for the UK economy.

Plan A was cut the deficit and by this remove prssure on the hard pressed 'wealth creating' sector.
Plan B was print money to reduce interest rates and encourage investment (Quantitative Easing).


The authors argue that Plan B would not work due to theoretical issues raised by Keynes. They then back this up with evidence from the experience of QE, principally pointing out that confidence is the main determinant of capital investment, not interest rates.


They present Friedman's argument that liquidity is a key element of preventing depression, but don't give it the credit it deserves. Perhaps because it is a short piece, or perhaps because they are both Keynesians and have been waiting thirty years for a chance to get their own back.


Whatever their motives their piece is an excellent survey and shows the requirement to understand how the relationships in the economy actually work before policy is designed. Sadly the theory often lags reality.
