Real personal income has generally been growing over the past year, while employment fell significantly in both November and December Recent data confirm our earlier conclusion that additional time is needed to be confident about the interpretation of the movements of the economy last year 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 would be a separate recession, not a continuation of the past one.

How long does the Committee expect the recession to last? The Committee does not forecast.
Does the Committee date recessions for individual countries in the euro area? No, the sole objective of the Committee is to date recessions for the euro area as a whole.

Why does the Committee not date recessions for individual countries? Is it possible that the EU area is in a recession while some of the individual countries are not?
The Committee wants to make sure that its characterization of Euro-area economic activity which is its sole objective is not affected by rising heterogeneity in the Euro-area. Adopting a dating criterion that refers solely to aggregate Euro-area economic activity achieves this objective most transparently.
Note that since October the Committee has dropped its requirement that peaks or troughs mark turning points in economic activity in most countries of the euro area.
It is thus possible that the EU-area is in a recession while some of the individual countries are not, and that the business cycle dates differ for the Euro-area and for individual countries.
For instance, Q3 is a peak in the Euro-area as a whole, but not for Germany. A detailed analysis of heterogeneity in individual countries' business cycles is included in the Committee's releases since its creation.

A: The Committee wants to ensure that its characterization of Euro-area economic activity which is its sole objective is not affected by rising heterogeneity in the Euro-area. The rationale for this definitional change is explained in detail in a methodological note.
It is thus possible that the euro area is in a recession while some of the individual countries are not, and that the business cycle dates differ for the Euro-area and for individual countries.
A: The Committee meets when it feels that data developments warrant examining whether there has been a turnaround in economic activity. Since Octoberthe Committee releases its findings after each meeting - whether or not it has decided to date a trough or a peak. Previously, it did so only after meetings that did date a turnaround.

Gregory Mankiw Victor Zarnowitz. January 13, This report is also available as a file. Rather, a recession is a significant decline in economic activity spread across the economy, lasting more than a few months, normally visible in real GDP, real income, employment, industrial production, and wholesale-retail sales. For more information, see the latest announcement from the NBER's Business Cycle Dating Committee, dated 9/20/
Real personal income has generally been growing over the past year, while employment fell significantly in both November and December Recent data confirm our earlier conclusion that additional time is needed to be confident about the interpretation of the movements of the economy last year 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 would be a separate recession, not a continuation of the past one.
The trough date will mark the end of the recession. The 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 make its decision, because of data revisions and the possibility that the contraction would resume.
For example, the committee waited until December to announce that a trough had occurred in March In Novemberthe committee determined that a peak in business activity occurred in the U. A peak marks the end of an expansion and the beginning of a recession. The determination of a peak date in March is thus a determination that the expansion that began in March ended in March and 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, visible 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 and 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 the economy broadly and is not confined to one sector, the committee emphasizes economy-wide measures of economic activity. The traditional role of the committee is to maintain a monthly chronology, so the committee refers almost exclusively to monthly indicators.
The committee gives relatively little weight to real GDP because it is only measured quarterly.
Does the Committee follow the NBER Business Cycle Dating Committee in its deliberations? While the CEPR Euro Area Business Cycle Dating Committee has been conceived to operate in a manner similar to the NBER Business Cycle Dating Committee, its deliberations and timing of announcements are independent. Apr 30, Business cycles refer to the cyclical increases followed by decreases in production output of goods and services in an economy. The stages in the business cycle include expansion, peak, recession.

The committee generally studies two monthly measures of activity across the entire economy: 1 employment and 2 personal income less transfer payments, in real terms adjusted for price changes. In addition, the committee refers to two indicators with coverage primarily of manufacturing and goods: 3 the volume of sales of the manufacturing and wholesale-retail sectors adjusted for price changes and 4 industrial production.
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 by the NBER in developing its business cycle chronology, there is no fixed rule about which other 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 slightly from May through October with a slight decrease in Septemberthen fell by 88, in November an in December, the most recent reported month.
Employment in December was only 29, above its lowest post-peak value, that of April Figure 2 shows the movements of real personal income less transfers. 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 in 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 most recent reported month.
Figure 4 shows real manufacturing and wholesale-retail sales. This measure reached a peak in Junedeclined until it plunged in Septembergenerally grew through Julybut then declined through October, the most recent reported month.
It is still above its level at the peak in March Figure 1. Current Employment The dark line shows the movement of employment in and the shaded line the average over the past 6 recessions. Figure 2. Real Personal Income Less Transfers The dark line shows the movement of income in and the shaded line the average over the past 6 recessions. Figure 3. Industrial Production The dark line shows the movement of industrial production in and the shaded line the average over the past 6 recessions.
Figure 4. Real Manufacturing and Wholesale-Retail Sales The dark line shows the movement of sales 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 past 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.

GDP reached a peak in the fourth quarter of This was followed by contraction during the first three quarters of and growth since then. In the fourth quarter ofreal GDP surpassed the earlier peak.
This performance of real GDP is consistent with the other data considered by the committee. Output fell less than employment during the recession and currently is rising faster than employment because of unusual productivity growth.

FAQs Q:Suppose that the current weakness of the economy continues, contrary to current forecasts. How will the NBER decide about turning points? A: The first step will be to determine if the period of weakness that began in late amounts to a recession.
The business cycle goes through four major phases: expansion, peak, contraction, and trough. All businesses and economies go through this cycle, though the length varies. The Federal Reserve helps manage the cycle with monetary policy, while heads of state and governing bodies use fiscal policy.
In this determination, we would refer to our standard criteria of depth, duration, and dispersion. The definition of a recession is stated in the third paragraph of this memo. The second step would be to determine if the recession starting in late was a continuation of the recession that we have already determined began in March We would decide in favor of a single, longer recession if we determined that economic activity in the period from March through late never surpassed its peak in March Here, we would have to reconcile the conflicting behavior of output and employment.
Output surpassed its previous peak in latewhile employment rose only slightly from its lowest level of April to the highest level it reached inin August.
