Now to the additional point I really wanted to make. When people invoke the idea of confidence, other people (particularly economists) should be automatically suspicious. The reason is that it frequently allows those who represent the group whose confidence is being invoked to further their own self interest. The financial markets are represented by City or Wall Street economists, and you invariably see market confidence being invoked to support a policy position they have some economic or political interest in.
Bond market economists never saw a fiscal consolidation they did not like, so the saying goes, so of course market confidence is used to argue against fiscal expansion. Employers drum up the importance of maintaining their confidence whenever taxes on profits (or high incomes) are involved. As I argue in this paper, there is a generic reason why financial market economists play up the importance of market confidence, so they can act as high priests. (Did these same economists go on about the dangers of rising leverage when confidence really mattered, before the global financial crisis?)
The general lesson I would draw is this. If the economics point towards a conclusion, and people argue against it based on ‘confidence’, you should be very, very suspicious. You should ask where is the model (or at least a mutually consistent set of arguments), and where is the evidence that this model or set of arguments is applicable to this case? Policy makers who go with confidence based arguments that fail these tests because it accords with their instincts are, perhaps knowingly, following the political agenda of someone else.
I generally agree with this based on facts on the ground. At the same time, Keynes emphasized the role of business confidence. Keynes held that business confidence was a function of effective demand and that a government's fiscal policy could address that potential loss of confidence by supplementing demand should effective demand contract owing to demand leakage resulting from increased liquidity preference.
There is a huge difference between inflation fighting, especially when there is little inflation in sight, "sound finance," monetary "discipline" and fiscal austerity, and bolstering effective demand by loosening the fiscal stance to address demand leakage to increased private or (inclusive) external saving desire, whether this is due to domestic private saving or a trade deficit.
Those who are monetarists of one sort or another hold that business confidence is chiefly a function of central banks' monetary policies. Fiscalists of whatever sort that follow Keyes, at least, connect business confidence with effective demand and see fiscal policy as the tool to address it, shifting the government's fiscal stance as appropriate to shifting non-government saving desire. For one thing, fiscal policy can be tightly targeted, whereas monetary policy is a shotgun approach.
