The economy has been on a roller coaster ride since the cyclical peak of December 2007. (See illustration.) The gradual slide of early 2008 turned into a terrifying freefall in the last quarter of 2008 (after the Lehman Brothers bankruptcy) and the first quarter of 2009. Now the train is probably at the bottom of the roller coaster valley.

The Index of Leading Economic Indicators, represented by the first car in the train, was this morning reported to have risen for the seventh consecutive month in October. Similarly, consumer confidence is substantially improved relative to February (though it, like all economic statistics, has experienced some bumps in the ride). The important middle cars, which represent measures of aggregate output, probably reached bottom in the early summer, and then started back up.  The BEA’s advanced estimate for GDP growth in the third quarter was 3 ½ % .

The jobs measures are lagging well behind the rest of the train, as usual.
Among three key labor market measures, the hours worked series has apparently reached the bottom. Employment is still falling, though thankfully not at the very rapid pace of a year ago. The unemployment rate brings up the rear; people in that car are understandably unhappy.

The quip “There are three kinds of lies:  lies, damn lies, and statistics” is variously attributed to Benjamin Disraeli or Mark Twain.   What should the public make of government statistics, such as the monthly employment report released today, Thursday, July 2, by the U.S. Bureau of Labor Statistics (BLS)?  

There is no lying in US government statistics.   But there are always commentators who will use the numbers to make whatever point they want.     One should learn enough to be able to interpret the numbers for oneself.     That is the only way to prevent being misled.

Of the many numbers contained in the BLS reports, I view three as especially important.    

The most salient figure politically is the unemployment rate, which hit 9.5% in June, according to Thursday’s report.    This was the highest level since August 1983 and clearly reflects the current extent of distress in American labor markets.

Critics of the official statistics like to point out that the unemployment rate does not capture discouraged workers who have dropped out of the labor force because they couldn’t find a job.  True.  But the government isn’t trying to make the unemployment number look smaller.   Rather, it is just too difficult to decide who is a “discouraged worker,” as opposed to simply being out of the labor force.   So the BLS always defines only those who have looked for a job recently as being in the measured labor force.   This still allows us to compare changes in unemployment over time, which is the purpose of the unemployment rate.   The agency does compute a measure that attempts to include discouraged workers and part-time workers — the U-6 series — but I don’t think it is right to call this the “real unemployment rate.”   

The second important number in the labor market reports is employment, that is, the number of workers who have jobs, which was down another 467,000 in June.    This is the statistic to which the financial markets and macroeconomic forecasters pay the most attention on a monthly basis.  (In that sense, the question of discouraged workers is a red herring.)     Employment peaked in December 2007, the start of the recession.    Since then, we have lost 6 million jobs altogether.   The current recession is now both the longest-lasting and the deepest since the 1930s.    But at least the period of the steepest rate of job loss –  November 2008 to March 2009 – appears to be behind us.  

Two details about the jobs number.    First, the statisticians get the “employment” number through one method, by surveying establishments (employers), while the unemployment rate uses a measure of employment derived through a different method, by surveying households.   The employment number is generally considered more reliable because it is based on a wider survey — another reason to prefer it.  

The second point is that, for purposes of comparison across different business cycles, we still need to divide employment by something.     If not the labor force, then what?   We must, at a minimum, allow for population growth.    So it is useful to divide employment by total population.  This way we don’t have to attempt distinctions about which Americans might be prepared to take a job under the right circumstances.  The fraction of the population (civilian non-institutional) with jobs peaked at the end of the Clinton Administration, reaching 64 ½  % in January 2001.   It has now declined to 59 ½ %.

Although the financial markets pay most attention to the number of workers with jobs, employment is not much good for forecasting the overall economy, because it tends to be a lagging indicator.   Even when firms see economic activity starting to pick up, they delay hiring, because it is costly to find, hire, and train new workers – not to mention to fire them again if the recovery turns out abortive.   

For this reason, the third indicator is my personal favorite for gauging the business cycle in real time:  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 length of the workweek for the average worker.   The length of the workweek can be expected 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.    The phenomenon is called “labor hoarding.”  Conversely, when demand begins to rise, firms tend to increase the workweek, before they hire new workers.   (To take two historical examples, the “change in total hours worked” improved in both April 1991 and November 2001, which on other grounds were eventually declared to mark the ends of their respective recessions.)   

The workweek reached a historically short level in June: 33.0 hours.  Not a good sign.    As one consequence, total hours worked fell 0.8% that month, continuing the same rapid deterioration we have seen since last September, the month when Lehman Brothers failed and the recession worsened sharply.  

The bottom line for the economy:   despite signs in other areas that the recession is leveling out – most importantly, production and sales — the labor market indicators in themselves are not yet signaling a turning point.   Thus the June numbers confirm the evaluation I made a month ago, based on hours worked in May, that the apparent good news in the widely reported May employment number was probably an insignificant blip.   The bottom line for newspaper readers:   master your statistics, so that they can’t master you.

Payroll employment peaked in December, and according to numbers released today had declined by 260,000 jobs as of April. (Source: BLS.) Since we have not yet seen a single negative number on GDP growth, this job loss is easily the most tangible statistical evidence we have so far that the much-heralded recession indeed may have started in the first quarter of 2008.

It has been noted that the unemployment rate started out from a low level — averaging 4.6 % in 2007 — so that even after a period of gradual increase, it remains relatively low by historical standards: 5.0% in April. This is still inside the range that has usually been considered by politicians as too low to generate serious discontent (and by central bankers as too low to put downward pressure on wages and prices). But why, then, is there so much popular dissatisfaction with the economy?

One answer is the old “discouraged worker” effect. Workers who stop looking for a job are not counted in the labor force, and so are not counted as unemployed. There is an obvious way to capture this phenomenon. Compare employment to the entire population, rather than only to those who are actively in the work force. The chart does that. (These figures include farm jobs, as in the standard BLS employment ratio.)

The path of the employment/population ratio during the current decade has been remarkable. The steep slide in jobs that began with the 2001 recession continued thereafter, and actually accelerated in late 2002. Finally the freefall leveled out. (The Bush Administration trumpeted the turnabout in terms similar to those it now uses to sell the aftermath of the troop surge in Iraq: the response to an unacceptable casualty rate was to make things worse for a half-year, and thereafter to compare the post-surge rate of casualties to the high-point, rather than to the period that came before.)

Employment did indeed rise between the years 2003 and 2007. But it barely stayed ahead of population growth. It did very little to make up for the decline equal to 2-3% of the population that had taken place during the first two years of the Bush Administration. The labor force participation rate normally rises in a boom, as good labor market conditions lure workers out of homes, schools and retirement. This is certainly what happened during the record expansion of 1992-2000. But it did not happen during the most recent expansion. To the contrary, the labor force participation rate was at a minimum in 2007, even though that year appears to have been the peak of the business cycle. As a result, employment as a share of the population was well below what it had been at the preceding business cycle peak year (2000). The fraction of Americans with jobs shows a decline from 64.7% to 62.6%, which translates into 4.9 million missing jobs ! Little wonder that, as employment once again starts to decline even in absolute terms, workers are unhappy.
