In the coming period and probably years you should expect to hear, read and be submerged with mainstream economists coming out and assessing the structural budget deficit. Across most economies, these so-called “experts” will be arguing that the structural deficit in the nation is too high and deep cuts are needed to bring it into surplus. The importance of this debate is that they use the structural deficit estimates as an indicator of the fiscal stance being taken by the government and thus separate out the effect of the automatic stabilisers. The problem is that it is an inexact science. The mainstream approach is highly dependent on the NAIRU concept (see below) and thus will err on the side of concluding that the deficit is “too big” and “likely to cause inflation”, whereas it is probable that the deficit will be too small to underpin private savings and high levels of employment.
