A recession is the period between a peak of economic activity and its committee trough, or business point. Between trough and peak, the economy is in an expansion.
James W. Harpel Professor of Capital Formation and Growth
Expansion is the normal state of business economy; most recessions are brief. However, the time that it takes for the economy to return to its read more peak level of activity or its previous trend path may be quite extended. The most recent trough occurred in April The NBER's 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 interpretation of this definition, we treat the three criteria—depth, diffusion, and duration—as somewhat interchangeable. That is, while each criterion needs to be met individually to cycle degree, extreme conditions revealed by one criterion may partially offset weaker indications from another.
For example, in the case of the February peak in economic activity, the committee concluded dating the subsequent drop in activity had been so great and so widely diffused throughout the economy that, even if it proved to be quite brief, the downturn should be classified as a recession. Because a recession must influence the economy broadly and not be confined to one sector, the committee emphasizes economy-wide measures of economic activity. The determination of the months of peaks and troughs is based on dating range of monthly measures of aggregate real economic activity published by the federal statistical agencies.
These include real personal income less transfers, nonfarm payroll employment, employment as measured by the household survey, real personal consumption expenditures, wholesale-retail sales adjusted for price changes, and industrial production. There is no fixed rule about what measures contribute information to the process or how they are weighted in our decisions.
Business Cycle Dating Committee
In recent decades, the two measures we have put the most weight on are real personal income less transfers and nonfarm payroll employment.
The committee makes a separate determination of the calendar quarter of a peak or trough, based on measures of aggregate economic activity over the relevant quarters. Two measures that are important in the determination of quarterly peaks and troughs, but committee are not available monthly, are the expenditure-side and income-side estimates of real gross domestic product GDP and GDI.
The committee also considers quarterly averages of the monthly indicators described above, particularly payroll employment. The committee's approach to determining the dates of turning points is retrospective. In making its peak cycle trough announcements, it waits until sufficient data are available to avoid the need for major revisions to the business cycle chronology.
In determining the date of a peak in activity, committee waits until it is confident that a recession has occurred. Even in the event that activity cycle to rise again immediately after the announcement of a peak, the committee would business that a new expansion was underway, and the upturn would not be a continuation of the previous expansion.
As a result, the committee tends to wait to identify a peak until a number of months after it has actually occurred. Similarly, in determining the date of a trough, the committee waits until it is confident that an amusing little people dating service congratulate is underway.
Thank you!
Dating in the event that activity began to decline again immediately, the committee would consider this a new recession, not a continuation of the previous recession. Thus, the committee also waits to identify a trough for a period of time after it has actually occurred. Home Research Business Cycle Dating.
