What it means
The National Bureau of Economic Research was founded in the early twentieth century and brings together a large network of academic economists. It publishes working papers on everything from taxation to health and productivity, and many of those papers shape policy debates and later appear in journals.
Most business people meet the NBER through recession dating. A committee of economists decides, using a range of indicators, when the US economy peaked and when it reached its trough.
Its definition of a recession is a significant decline in economic activity that is spread across the economy and lasts more than a few months. Many people believe a recession simply means two consecutive quarters of falling gross domestic product (GDP, the total value of goods and services produced).
That is a popular rule of thumb, but the committee looks more broadly, including employment, income, spending, industrial production and wholesale and retail sales. The announcement usually comes well after the fact.
The committee waits for enough data to be confident, so a recession may be declared many months after it began, and the dates can be revised. Businesses therefore treat the NBER as the official record for history, not as a real-time warning system.
For finance teams the dates are useful in several ways. Analysts use them to test how a business or portfolio behaved in past downturns, to build stress scenarios and to compare the length of expansions and contractions across decades.
The long run of dates also reveals that expansions have generally lasted much longer than contractions, a helpful reminder when planning for the long term. The organisation is independent and not part of the government.
Its dates are therefore a respected reference rather than a legal definition, and other countries use their own bodies or rules to date their cycles. Anyone comparing downturns across countries should check how each one was dated.
In practice
Real-world examples.
Example
A CFO building a stress test for the company's budget looks up the NBER recession dates for the past fifty years. She measures how much the firm's revenue fell in each downturn and uses the worst case as a planning assumption.
Example
An investment analyst compares stock market returns in the twelve months before each NBER-dated recession began. He finds that markets often moved before the official start, which tells him that waiting for the announcement would have been too late. He therefore builds his own early-warning dashboard from credit spreads, hiring data and new orders.
Example
A university lecturer asks students to explain why the economy can be in recession even though GDP did not fall in two consecutive quarters. The students use the committee's broader definition to answer. They then discuss how the severity, breadth and duration of a downturn all count, not just the headline output figure.
Case study
Seen in the real world.
Ridgeway Components is an illustrative, fictional manufacturer that sells to the construction industry. Its finance team noticed that sales had weakened for several months, but management hesitated to cut costs because no official recession had been announced.
The CFO pointed out that the official dating committee works with a long delay and that the company's own order book was a far earlier signal. She presented a chart of the firm's past downturns against the official dates, which showed that the company's sales had always started falling several months before the recession was formally declared.
In this illustrative story, the board agreed to a staged cost plan triggered by internal measures such as order backlog and cash conversion, with the official dates used only to review the results afterwards. Eighteen months later the company had protected its cash and avoided the heavy cuts that competitors were forced into.
Watch out
Common mistakes.
- Believing the NBER defines a recession as two consecutive quarters of falling GDP, when its committee weighs a wider set of indicators.
- Waiting for an official announcement before acting, when the declaration normally arrives long after the downturn begins.
- Assuming the NBER is a government agency, when it is a private non-profit research organisation.
Questions
People also ask.
Who sits on the Business Cycle Dating Committee?
It is a group of academic economists chosen by the organisation, who meet when the data suggests a turning point and who have no fixed schedule for announcements.
Does the NBER cover countries other than the United States?
Its recession dating applies to the United States, although its researchers publish on many countries, so readers should not assume the dates apply abroad.
Can the dates change?
Yes, the committee can revise its dating if later data change the picture, although such revisions are rare, and the committee explains its reasoning in a public statement each time it announces a turning point.
