Nber dating

opinion

Gregory Mankiw Victor Zarnowitz January 13, According to the Nber dating recent data, Nber dating U. Real personal income has generally been growing over the past year, while employment fell significantly in both November and December Recent data Nber dating our earlier conclusion that additional time is needed to be confident about the interpretation of the movements of the economy last Nber dating and this year.

The NBER's Business Cycle Dating Committee will determine the date of a trough in activity when it concludes that a hypothetical subsequent downturn Nber dating be a separate recession, not a continuation of Nber dating past one. The trough date will mark the end of the recession.

Nber dating committee will not issue any judgment about whether the economy has reached a trough until it makes its formal decision on this point. The committee waits for many months after an apparent trough to Nber dating its decision, because of data revisions and the possibility that the contraction would resume. For example, the committee waited until Nber dating to announce that a trough had occurred in March In NovemberNber dating committee determined that a peak in business activity occurred in the U.

A peak Nber dating the end Nber dating an Nber dating and the Nber dating of a recession. The determination of a peak date in Nber dating is thus a determination that the expansion that began in March ended in March Nber dating a recession began in March.

The expansion lasted exactly 10 years and was the longest in the NBER's chronology. A recession is a significant decline in activity spread across the economy, lasting more than a few months, Nber dating in industrial production, employment, real income, and wholesale-retail sales.

A recession begins just after the economy reaches a peak of activity and ends as the economy reaches its trough. Between trough Nber dating peak, the economy is in an expansion.

Expansion is the normal state of the economy; most recessions are brief and they have been rare in recent decades. Because a recession influences Nber dating economy broadly and is not confined to one sector, Nber dating committee emphasizes economy-wide measures Nber dating economic activity.

The Nber dating dating role of the committee Nber dating to maintain a monthly chronology, so the committee refers Nber Nber dating exclusively to monthly indicators.

Business Cycle Expansion and contraction...

The committee gives Nber dating little weight to real GDP because it is only measured quarterly. The committee generally studies two monthly measures Nber dating activity across the entire economy: In addition, the committee refers to two indicators with coverage primarily of manufacturing Nber dating goods: Because manufacturing is a relatively small part of the economy, the movements of these indicators often differ from those reflecting other sectors.

Although the four indicators described above are the most important measures considered Nber dating the NBER in developing its business cycle chronology, there is no fixed rule about which Nber dating measures contribute information to the process. Figure 1 shows the recent movements of employment superimposed on the average movement over the past six recessions. Employment reached a peak in March and declined through April Current revised data show that employment rose Nber dating from May through October with a slight decrease in Nber dating fell by 88, in Nber dating andin Nber dating, the most recent reported month.

Employment in December was only 29, above its lowest post-peak Nber dating, that of April Figure 2 shows the movements of real personal income less Nber dating. Real income generally fell from late through lateand generally rose through the most recently reported month, Octoberexcept for a slight decline in July.

This indicator is now slightly above its previous peak Nber dating November Figure 3 shows industrial production. A peak occurred in June and the index declined over the next 18 months by 7. Industrial production rose between January and Septemberfell in October, but rose slightly again in November, the Nber dating recent reported month.

It is still above its level at the peak in March Current Employment The dark line shows the movement of employment in and the shaded line the average over the past 6 recessions.

Inindicators measuring output and income generally have been rising, while employment has been essentially constant until its significant decline in the Nber dating two months. The primary factor accounting for the more favorable performance of income and production relative to employment is the continuation of rapid productivity growth resulting in corresponding growth in real wages.

According to data released in December http: GDP reached a peak in the fourth quarter of This was followed by contraction during the first three Nber dating of and growth since then. In the fourth quarter ofreal GDP surpassed the earlier peak.

How does that relate to...

This Nber dating of real GDP is consistent with the other data considered by the committee. Output fell less than Nber dating during the Nber dating and currently is rising faster than employment because of unusual productivity growth. For more information, see the FAQs at the end of this memo, and also see http: Files containing the data and figures is available from that page as well. Suppose Nber dating the current weakness Nber dating the economy continues, contrary to current forecasts.

How will the NBER decide about turning points? The first Nber dating Nber dating be to determine if the Nber dating of weakness that began in late amounts to a recession. In this determination, we would refer to our Nber dating criteria of depth, duration, and dispersion.

The definition of a recession is stated in the Nber dating paragraph of this memo. The second step would be to determine if the recession Nber dating dating in late was a continuation of the recession that we have already determined began in March We would decide in favor Nber dating a single, longer recession if we determined that economic activity in the period from March Nber dating late never surpassed its peak in March Here, we would have Nber dating reconcile the conflicting behavior of Nber dating and employment.

Output surpassed its previous peak in latewhile employment rose only slightly from its lowest level of Nber dating to the highest level it reached inin August.

At that time, employment was still 1. The financial press often states the definition of a recession as two consecutive quarters of decline in real GDP. How does that Nber dating Nber dating the NBER's recession dating procedure?

Most of the recessions identified by our procedures Nber dating consist of two or more quarters of declining real GDP, but not all of them.

According to current data forthe present recession falls into the general pattern, with three consecutive quarters of decline. Our procedure differs from the two-quarter rule in a number of ways. Nber dating, we use monthly indicators to arrive at a monthly chronology. Second, we use indicators subject to much less frequent revision. Third, we consider the Nber dating Nber dating the decline in economic activity.

Recall that our definition includes the phrase, "a significant decline in activity. Some observers, however, cite April as Nber dating start of the recession, reasoning Nber dating if the peak ended in March, then the recession began in April. The exact peak occurred sometime in March.

For the rest of the days in March, the economy was in recession. Nber dating the expansion ended and the recession began Nber dating March. Isn't a recession a period of diminished economic activity? It's more accurate to say that a recession-the Nber dating we use the Nber dating a period of Nber dating activity rather than diminished activity.

We identify a month when Nber dating economy reached a peak of activity and a later month when the economy Nber dating a trough. The time in between is a recession, a Nber dating when the economy is contracting. The following period Nber dating an expansion. Economic activity Nber dating below normal or diminished for some Nber dating of the recession and for some Nber dating of the following expansion as well.

Some call the period of diminished activity a slump. Following the precedents established Nber dating many decades of maintaining Nber dating business cycle chronology, the NBER considers employment, production, sales, and real income.

The NBER's Recession Dating Procedure....

When special factors-such as unusual productivity growth and favorable shifts in the terms of trade-make income Nber dating production-based measures move differently from those based Nber dating employment, we Nber dating the two types of evidence. You emphasize the payroll survey as a source for data on economy-wide employment.

What about the household survey? Although the household Nber dating is a large, well-designed probability sample of the U. The two sources agree reasonably closely Nber dating the movement of employment Nber dating this recession.
