The Unemployment Rate

I just wanted to clarify a couple of things that came up in class and offer some criticisms (by others) of the unemployment rate.

For my own benefit, Alternative measures of the unemployment rate: Table A-12 has been changed to A-15.

A couple of graphs first:



U-3 vs U-6 unemployment since Jan 2007.




U-6 as a percentage of U-3 since Jan 2007


Finally, here is a comparison between the seasonally adjusted numbers and the "raw" series (this is U3).


Seasonally Adjusted and Unadjusted


Okay, I want to clarify "marginally attached" and "discouraged workers". Discourages workers make up about half of marginally attached workers. Also note that to be considered either marginally attached or discourages you either have to have been employed or have looked for a job within the last year. Otherwise you are not part of the labor force at all.

From the BLS glossary:

Marginally attached workers (Current Population Survey)
Persons not in the labor force who want and are available for work, and who have looked for a job sometime in the prior 12 months (or since the end of their last job if they held one within the past 12 months), but were not counted as unemployed because they had not searched for work in the 4 weeks preceding the survey. Discouraged workers are a subset of the marginally attached.


Discouraged workers (Current Population Survey)
Persons not in the labor force who want and are available for a job and who have looked for work sometime in the past 12 months (or since the end of their last job if they held one within the past 12 months), but who are not currently looking because they believe there are no jobs available or there are none for which they would qualify.


Someone had also asked about how illegal immigrants are counted. From the Q&A page:

Does the household survey count illegal immigrants?
The BLS cannot determine to what extent illegal immigrants are reflected in the household survey, though it is likely that it does include some illegal immigrants. The household survey does not include questions to identify one’s legal status, but it does include questions about whether respondents were born outside the U.S. The CPS shows that foreign-born workers (whether legal or illegal) accounted for about 16 percent of the labor force in 2007 and about 48 percent of the net increase in the labor force from 2000 to 2007.



Okay so time for some criticism:

Eric from Sunday Macro sent me a couple of articles by a NY Post columnist John Crudele. One of them outlines a number of things that are worth addressing. Bear in mind that this was written after the December unemployment numbers was released. I essentially agree with Crudele except his tone and his complaints about the "birth/death" model which as far as I can tell has nothing to do with the "headline" unemployment number.

The birth/death model is a statistical tweaking of the Current Employment Survey (CES) which is a survey of businesses. The CES numbers accompany the unemployment press release but does not factor into the "unemployment rate" that comes from the Current Population Survey (CPS) which is a survey of households. The CES contains a lot of information about hiring and firing in industries and gives an overall picture of "jobs created or lost" but it is separate measure. They fill in gaps in their ability to survey new business or firms that have go out of business with an estimation, this birth/death model.

Its important to keep this in mind because often news reports will say "x numbers of jobs lost" which comes from the CES (business survey) and then the "unemployment rate" which comes form the CPS (household data). Those numbers may not make sense when put together but its reasonable that they do not since they measure different things.

As far a Crudele's tone. I'm perfectly fine with criticizing the statistical measures. However, because these are statistical measures (not facts!) there are necessarily somewhat arbitrary judgments that need to be made and it is impossible to make such judgments in a way that defy criticism.

I agree that there is probably some amount of "politicking" going on with the numbers to engineer them to look better. The Goolsbee anecdote in the article though is a good example of the politicking involved in criticizing the number too. One thing that bugs me about Crudele is that he often invokes John Williams' who runs Shadow Government Statistics (SGS). SGS publishes alternative economic indicators (such as unemployment and inflation). The SGS numbers always look worse than the official numbers and John Williams has made some apocalyptic claims that garnered a lot of attention like in this Reuters article from January of last year:

By his count, if unemployment were still tallied the way it was in the 1930s, today's jobless rate would be closer to 16.5 percent -- more than double the stated rate.

I expect that unemployment in the current downturn, which will be particularly deep and protracted, eventually will rival, if not top, the 25 percent seen in the Great Depression," Williams said.

Ignoring the fact that the BLS did not calculate the unemployment rate in the 30s my big issue with John Williams is that--try as I might--I have not found any hints to his methodology for his alternative measures. The BLS on the other hand has wholly transparent data and methodology which is for my money the best and most honest thing you can do with any kind of statistical work. Such a thing requires a lot of work by the press and by citizens, which I suppose is the real problem.


Anyway here is the article. It reiterates a lot of the stuff I brought up in class:

Jan 12, 2010

This'll make you laugh.
Back in November 2003 an economist named Austan Goolsbee from the University of Chicago wrote an op-ed piece for The New York Times criticizing a Labor Department announcement about job growth the month before.

And he attacked the idea that the country had just experienced nothing more than a mild recession.

"Unfortunately, underreporting unemployment has served the interest of both political parties," wrote Goolsbee. "The situation has grown so dire, though, that we can't tell whether the job market is recovering."

OK, I promised you a laugh. So here it comes.

Goolsbee no longer works at the University of Chicago. He now has a job at the White House as President Obama's top economic adviser.

So the president and Goolsbee will now have to convince the American public that the slight statistical improvement in the employment situation over the past year really is credible -- even if Goolsbee doesn't believe it.

Laughing yet? Of course not. There's nothing funny about what we went through either back in 2003 after the 9/11 terrorist attacks or what we are experiencing now.

As you already know the Labor Department last Friday announced that another 85,000 jobs disappeared from the economy in December and that the unemployment rate stayed, unbelievably, at 10 percent.

On one level it was -- to say the least -- a disappointment for the White House, Wall Street and every American who is out of work or thinks they might be.

Yet on another level, the negative 85,000 figure was a blessing for Goolsbee and President Obama.

At least, as they are quick to point out, this job loss wasn't as bad as the hundreds of thousands per month that were coming earlier this year.

As any regular reader of this column already knows, I take the side that Prof. Goolsbee took when he was in Chicago -- the government's employment numbers aren't believable.
I thought it would be interesting today to present a few (not-so) fun facts about the jobs market.

Fact 1: The next employment report will be worse.
When the Labor Department puts out the January employment figures on Feb. 4, they will include an assumption that a lot of companies went out of business.
This is something called the birth/death model that is used by the department. Last year it caused 356,000 jobs to be subtracted from the January job count.
So, the next employment figure should be shockingly bad.

Fact 2: The birth/death model will then turn optimistic in the spring, causing jobs that really don't exist to be added to the Labor Department's count.

It won't make the people who are unemployed feel any better. But it could give Wall Street another excuse to rally and, really, isn't that what it is all about?

Fact 3: Nobody in the media will pick up on this, but the Labor De partment will also do something called a benchmark revision on Feb. 4 that will subtract around 840,000 jobs that the government thought existed, but really don't.

This will mostly make up for the mistakes created by the birth/death model.

Fact 4: That 840,000 job adjustment will only correct errors up to March 2009. Mistakes for the April 2009 to March 2110 period will be corrected next year.

Fact 5: You keep reading that the unemployment rate stayed at 10 percent. But the press has been playing up the 17.3 percent rate that includes those "underemployed," meaning they can't find a full-time job but want one.

I've been mentioning that under-employed figure -- called U-6 by the Labor Department -- for years and I'm glad everyone else has finally caught up.

But that larger figure doesn't include a huge number of unemployed folks who have given up looking for work because they feel the search is hopeless. Last Friday's report said 661,000 such people left the labor force in December.

If you count these hopelessly unemployed, the real jobless rate is probably close to 22 percent. If these all weren't such important issues, this would all be a big joke.

Contributions to the Change in Nonfarm Payroll Employment

From Economist's View:
June 8, 2009



The graph is from "Are there green shoots in the labor market?" by Melinda Pitts and Menbere Shiferaw of the Atlanta Fed. They say "it is promising that the labor market is at least producing some variation from the negative trends." However, see also Jobless Recovery Redux? from Mary Daly, Bart Hobijn, and Joyce Kwok of the SF Fed. They say "Our analysis generally supports projections that labor market weakness will persist, but our findings offer a basis for even greater pessimism about the outlook for the labor market."

Update: Jeff Frankel, a member of the NBER Business Cycle Dating Committee, says we haven't hit bottom yet:

The labor market has NOT yet signaled a turning point: The rate of decline in employment fell abruptly in May, according to the BLS figures released June 5, to about half the monthly rate of job loss recorded over the preceding six months (345,000 vs. 642,000). The news was received in a variety of ways.

First, the cynics. They tend to wax sarcastic at the idea of “things are not getting worse quite as fast as they were” as a good-news proposition. But a wide variety of recent data indicate that the economy is no longer in the state of free-fall that it entered last September, and this is indeed good news. ...

Second, the academics note (correctly) that there is little information in each individual monthly statistical fluctuation that is measured, because the data are inevitably noisy. Still, the public wants to know, in real time, what is the best we can glean from the information we have.

Third, the financial press, in particular, had been asking whether this quarter could turn out to have be the bottom of the recession. The May employment report encouraged speculation that the answer was “yes.” The stock market went up.

The members of the NBER Business Cycle Dating Committee (of which I am one) will be responsible for calling the trough when the time is right. We have a range of views... But all of us agree, on the one hand, that a decline in economic activity is a decline in economic activity, and therefore still a state of recession, even if the rate of decline has moderated a lot. But I believe that we also agree, on the other hand, that employment is usually a lagging indicator of economic activity. (For example, the economy continued to lose jobs long after the ends of the 1991 and 2001 recessions. Hence the “jobless recoveries.”)

Speaking entirely for myself, I like to look at the rate of change of total hours worked in the economy. Total hours worked is equal to the total number of workers employed multiplied by the average length of the workweek for the average worker. The length of the workweek tends to respond at turning points faster than does the number of jobs. When demand is slowing, firms tend to cut back on overtime, and then switch to part-time workers or in some cases cut workers back to partial workweeks, before they lay them off. Conversely, when demand is rising, firms tend to end furloughs, and if necessary ask workers to work overtime, before they hire new workers. (The hours worked measure improved in April 1991 and November 2001 which on other grounds were eventually declared to mark the ends of their respective recessions.) The phenomenon is called “labor hoarding” and it is attributable to the costs of finding, hiring and training new workers and the costs in terms of severance pay and morale when firing workers.

Unfortunately, as reported by Forbes, pursuing this logic leads to second thoughts about whether the most recent BLS announcement was really good news after all. The length of the average work week fell to its lowest since 1964 ! The ... rate of decline (0.7%) was very much in line with the rate of contraction that workers have experienced since September. Hours worked suggests that the hope-inspiring May moderation in the job loss series may have been a minor aberration. If firms were really gearing up to start hiring workers once again, why would they now be cutting back as strongly as ever on the hours that they ask their existing employees to work? My bottom line: the labor market does not quite yet suggest that the economy has hit bottom.

He has a graph of hours worked. Also see: The ‘part-timezation’ of America at FT Alphaville.
