About that confidence fairy. This is from Simon Wren-Lewis

Confidence: Francesco Saraceno reminds us about the days in which very important people believed in the confidence fairy (aka expansionary fiscal austerity), which are not so very far away. He also points to some recent ECB research which shows that confidence - as measured by surveys - clearly falls following fiscal austerity. The confidence fairy, rather than waving her wand to make everything alright again, may be making austerity worse. 
However, looking at the research in detail revealed some results I found at first surprising. In particular, revenue cuts have a bigger effect on consumer confidence than spending cuts. In terms of GDP impacts, theory - and most but not all empirical evidence - suggests that temporary spending cuts will have a larger impact on overall activity than temporary tax increases, if there is no monetary offset and incentive effects are not very large. Do these empirical results contradiction this?
To answer that you need to ask two further questions. First, what does consumer confidence actually measure? Second, and perhaps more interesting, what information do fiscal announcements actually reveal. ...[goes on to explain]...
Trying to evaluate the impact of past fiscal actions is complicated, in large part because it is difficult to know what the counterfactual was, or what people thought the counterfactual was. Were changes thought to temporary or permanent? (Governments hardly ever say, and even if they did would they be trusted?) To what extent do people internalise the government’s budget constraint? If they do, are fiscal changes telling us about the timing of taxes or spending, or their mix, or something else? It seems to me that these difficulties arise whether we are trying to assess the impact of fiscal changes on confidence, or on activity itself.
