It is noticeable that, with the exception of the one coincident dating, our dating tends to lead ECRI's. However, as explained at greater length in Artis et al.

The particular selections made in the rules used in this paper to isolate the classical cycle turn out to produce results qui te close but generally with a short lead to those already established by ECRI, which embodies the NBER tradition in business cycle dating. The chart shows the periods of expansion and recession for the Composite Coincident Indicator Index from to Even whilst avoiding the most obvious of these pitfalls it must immediately be obvious that the objective of precision in dating will be compromised by the smoothing involved in the de-trending.

The classical cycle The concept of the classical cycle has recently reclaimed a degree of popularity.

The dates of peaks identified by Krolzig and Toro in the period covered by the present study are: Note that the series typically climbs during expansion periods between the trough and the peak of the business cycle and falls during recessions the shaded areas between the peak and the trough.

This index, published by The Conference Board http: Using the methodology of the Markov chain, it can be show n how the various restrictions listed here can be enforced and how they can be supplemented by additional restrictions on amplitude if desired: Such a definition could lead to a peak trough being identified even when the observation in question was below above trend and needs to be supplemented to avoid this contingency: The data are in principle already seasonally adjusted at source; the idea is simply to remove outliers and any excess seasonality that may remain.

For the case of the deviation cycle the correspondence is not so close as, in general, might be expected. The remainder, slightly less than a quarter of the total, is simply interpolated from quarterly series on the output components involved -- agriculture and non-marketed public services -- and does not represent the use of data points observed at the monthly level.

The procedure leading to the identification of the turning points in GDP can easily be replicated for the component series and the 'stylized facts' Pagan, calculated: These criteria have been inherited from the computer algorithm devised by Bry and Boschan to mimic for a univariate series the identification procedures implemented by the NBER in its cycle dating Dating the business cycle in britain.

It is noticeable that construction and industrial production are about equally cyclical, judged by the number of cycles identified in the period, and are much more cyclical than the service sectors or GDP as a whole.

The demands of a classical cycle dating algorithm are relatively few: It can be seen that the two phases are in fact about equally steep, the larger expansion amplitudes being offset by their greater duration. What are business cycles and how do they affect the economy? The Baxter-King filter -- or almost-ideal band-pass filter -- has gained in popularity recently perhaps because it promises to be less arbitrary.

For dating purposes, however, even the quarterly frequency is rather coarse; for a given 'true' incidence of peak or trough in a given month, the corresponding registration of that peak or trough in quarterly data can easily slip by a quarter.

Second, the data shown on the relative frequency, duration and amplitude now indicate a high degree of symmetry in the cycles identified, as opposed to the case with the classical cycle.

Gross Domestic Product is widely accepted as the best measure we can think of to represent the general level of economic activity and it is generally assumed that the measure takes adequate account of the 'pervasiveness' that is required in the definition of the cycle.

The same number of cycles is identified in the period in question and the turning points identified are generally within three months of each other and in one case coincident. For example, it would seem desirable to eliminate seasonal fluctuations, and possibly what appear to be outlier observations preferably, where these can be identified with a causal event, like a strike, or a bad harvest.

Subsequently, the Bry-Boschan BB algorithm has also been adapted for data at the quarterly frequency as in Boundless missionary dating for examplewhilst eliminating some of the steps suggested in the original.

The table shows a number of items of interest. Data on these official business cycle turning points and dates are available from the NBER website at http: Between trough and peak, the economy is in an expansion. Three classical cycles are detected in the period between the early s andwith turning points which are close to but usually precede classical cycle dating which does not benefit from the availability of monthly GDP, and instead relies on a 'coincident' indicator methodology.

Krolzig and Toro do not provide a deviation cycle dating, and whilst there are many papers dealing with the growth cycle on quarterly and annual UK data Artis, Marcellino and Proietti is a recent examplenot many provide a chronology of turning points; at the same time, the methods of detrending used differ considerably, as do the data vintages and frequencies used, so that it appeared comparatively uninformative to attempt further comparisons here.

This removes the possibility of confusing cyclical with merely seasonal fluctuation, or confounding the reaction to a strike with a cyclical phenomenon.
