When The Definition Of A Recession Matters

The official Definition of a recession inwards nearly all developed economies except the U.S.A. is 2 consecutive quarters of negative growth. In the U.S.A. a recession is ‘called’ yesteryear the NBER. Economists, of course, but facial expression at the numbers. This is manifestly the sensible affair to do, because a autumn inwards gross domestic product of 3% followed yesteryear positive increment of 0.1% is clearly worse than 2 periods of -0.1% growth, but alone the latter is an official recession. The media on the other mitt behaves differently, hence nosotros had the lightheaded province of affairs inwards the Great Britain earlier 2013 when tiny revisions to gross domestic product led to headlines similar ‘UK avoids double dip recession’.

Yet this youngster annoyance for people similar me has been turned into an chance inwards a recent newspaper (pdf) yesteryear 2 political scientists at the LSE (HT David Rueda). Andrew Eggers in addition to Alexander Fouirnaies facial expression at the information to encounter if the annunciation of a recession causes whatever additional bear upon on macroeconomic aggregates compared to what y'all mightiness await from the gross domestic product information itself. In other words, does the annunciation of a recession trim consumption or investment inwards OECD countries, conditional on actual economical fundamentals? For ease I’ll telephone band this an annunciation effect.

For investment they teach the answer that economists would promise for - at that topographic point is no annunciation effect. Firms are good informed, in addition to but facial expression at the numbers. However for consumption they practise uncovering a pregnant annunciation effect, both inwards terms of the actual information (and the size of the bear upon tin live non-trivial) in addition to inwards terms of consumer confidence indicators. One lastly final result they emphasise, which makes clear feel from a macro betoken of view, is that the bear upon of recession announcements on consumer spending inwards smaller inwards countries amongst to a greater extent than robust social security nets.

There are many reasons why this is interesting, but allow me focus on i that I own got discussed before. In this post I pointed to a potential paradox. On the i mitt I believe that for most macroeconomic problems, rational expectations rather than naive expectations is the correct house to start. On the other mitt I too intend that media reporting tin own got a strong influence on the average persons persuasion on for certain highly politicised issues, similar is man-made climate modify a serious problem, or how of import is the terms of welfare fraud. I discussed this paradox here, in addition to argued that it could easily live resolved yesteryear thinking almost the costs in addition to benefits of obtaining information. In particular, the costs of researching climate modify are significant, whereas the terms to the individual of getting their ain persuasion incorrect is almost zero. (This is but a variation on the paradox of voting.)

In the illustration from this paper, nosotros own got a measure macroeconomic problem, which is trying to assess what degree of consumption to choose. The importance of the annunciation upshot suggests that for consumers the costs of ‘looking at the numbers’ (and, of course, interpreting them) to roughly extent exceeds the benefits of going beyond media headlines. If the media tin own got an influence on something that clearly has a pregnant fiscal pay-off for individuals, hence it is outpouring to influence attitudes when the personal costs of making mistakes is almost zero.
