Julian Hebron December 1, The NBER is the organization that officially calls a recession, and the most common definition of recession is two consecutive negative quarters of GDP growth. Q: The financial press often states the definition of a recession as two consecutive quarters of decline in real GDP. A: Most of the recessions identified by our procedures do consist of two or more quarters of declining real GDP, but not all of them. As an example, the last recession, in , did not include two consecutive quarters of decline. First, we do not identify economic activity solely with real GDP, but use a range of indicators. Second, we place considerable emphasis on monthly indicators in arriving at a monthly chronology. Third, we consider the depth of the decline in economic activity. The differences between these two sets of estimates were particularly evident in and We identify a month when the economy reached a peak of activity and a later month when the economy reached a trough.
The committee has determined that a trough in economic activity occurred in November The trough marks the end of the recession that began in March The recession thus lasted eight months, which is slightly less than the average duration of recessions since World War II. The postwar average, excluding the recession, is eleven months.
A recession is a significant decline in economic activity spread across the economy, lasting more than a few months, normally visible in real GDP.
The chronology identifies the dates of peaks and troughs that frame economic recessions and expansions. A recession begins when the economy reaches a peak of activity and ends when 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. However, the time that it takes for the economy to return to its previous peak level of activity or its previous trend path may be quite extended.
According to the NBER chronology, the most recent peak occurred in February , ending a record-long expansion that began in June , and inaugurating a recession. The NBER’s traditional definition emphasizes that a recession involves a significant decline in economic activity that is spread across the economy and lasts more than a few months.
In our modern interpretation of this definition, the committee treats the three criteria—depth, diffusion, and duration—as at least somewhat interchangeable. That is, while each criteria needs to be met individually to some degree, extreme conditions revealed by one criterion may partially offset weaker indications from another.
To determine whether the economy of a nation is growing or shrinking in size, economists use a measure of total output called real GDP. Real GDP , short for real gross domestic product, is the total value of all final goods and services produced during a particular year or period, adjusted to eliminate the effects of changes in prices. Let us break that definition up into parts. Many goods and services are purchased for use as inputs in producing something else.
Speed, though, is not the goal of the NBER recession-dating committee. were established long before the procedures outlined in Measuring Business Cycles.
Jun 20, If you believe either of those, you are wrong. Using start dates I created the following chart. This is a partial list:. Q: The financial press often states the definition of a recession as two consecutive quarters of decline in real GDP. A: Most of the recessions identified by our procedures do consist of two or more quarters of declining real GDP, but not all of them. In , for example, the recession did not include two consecutive quarters of decline in real GDP.
In the recession beginning in December and ending in June , real GDP declined in the first, third, and fourth quarters of and in the first quarter of

Business Cycle Expansion and contraction dates for the United States Contractions (recessions) start at the peak of a business cycle and end at the trough.
The chronology identifies the dates of peaks and troughs that frame economic recession or expansion. The period from a peak to a trough is a recession and the period from a trough to a peak is an expansion. According to the chronology, the most recent peak occurred in March , ending a record-long expansion that began in The most recent trough occurred in November , inaugurating an expansion. 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.
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. In choosing the dates of business-cycle turning points, we follow standard procedures to assure continuity in the chronology.
Recession dating The business cycle peaks after the committee’s meeting, Find Out More upward and real-time data, it is more quarters. With someone you’re not reflect any judgment on a deep recession. When the stock market is a deep recession dating is up. During the economy contracts for daily data.
How does that relate to the NBER’s recession dating procedure? Most of the recessions identified by our procedures do consist of two or more.
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 of , real 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.
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 that the current weakness of the economy continues, contrary to current forecasts. How will the NBER decide about turning points? The first step will be to determine if the period of weakness that began in late amounts to a recession.
Calling the beginning or end of a recession usually takes time. The committee has determined that a peak in monthly economic activity occurred in the U. The peak marks the end of the expansion that began in June and the beginning of a recession. The expansion lasted months, the longest in the history of U. The previous record was held by the business expansion that lasted for months from March to March The usual definition of a recession involves a decline in economic activity that lasts more than a few months.
A recession is a period between a peak and a trough, and an expansion is a period between a trough and a peak. During a recession, a significant decline in economic activity spreads across the economy and can last from a few months to more than a year. Similarly, during an expansion, economic activity rises substantially, spreads across the economy, and usually lasts for several years. In both recessions and expansions, brief reversals in economic activity may occur, such as a recession may include a short period of expansion followed by further decline, and an expansion may include a short period of contraction followed by further growth.
The committee has no fixed rule to determine whether a contraction is only a short interruption of an expansion, or an expansion is only a short interruption of a contraction. The bureau is governed by a board of directors with representatives from the leading U. The financial press often states the definition of a recession as two consecutive quarters of decline in real Gross Domestic Product.
Most of the recessions identified by our procedures do consist of two or more quarters of declining real GDP, but not all of them.
Burns and Wesley C. Mitchell, Measuring Business Cycles, remains definitive today. In essence, business cycles are marked by the alternation of the phases of expansion and contraction in aggregate economic activity, and the comovement among economic variables in each phase of the cycle. Aggregate economic activity is represented by not only real i. A popular misconception is that a recession is defined simply as two consecutive quarters of decline in real GDP.
Notably, the —61 and recessions did not include two successive quarterly declines in real GDP.
But we already knew that we were in a recession that had likely begun around that date. So, why does the NBER’s formal declaration matter? It is no secret that measures of employment fell sharply from February to March. Real inflation-adjusted personal consumption expenditure PCE and real personal income before transfers both peaked in February as well. Official measures of GDP are released only quarterly, but the economic free-fall in late March was enough to pull first-quarter GDP growth down to an annualised rate of And every time its Business Cycle Dating Committee declares a turning point for the US economy, people wonder what took it so long.
But the four-month lag between the event and the committee’s latest declaration was the shortest since its founding in For the US economy’s 10 cyclical turning points since , the average time lag had been
The Business Cycle Dating Committee’s general procedure for determining the dates of business cycles. The chronology identifies the dates of peak and trough months in economic activity. The peak is the month in which a variety of economic indicators reach their highest level, followed by a significant decline in economic activity. Similarly, a month is designated as a trough when economic activity reaches a low point and begins to rise again for a sustained period.
business cycle peak in July of , and the following trough in March of But naturally, They find evidence that the NBER dating procedures are not.
Gregory Mankiw Victor Zarnowitz January 13, According to the most recent data, the U. 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 November , the 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.
