from Market Oracle:
Month after month, with the exception of January, the BLS is assuming more jobs were created by new businesses than lost by businesses closing shop. The BLS model is horribly wrong.
BLS Black Box
For those unfamiliar with the birth/death model, monthly jobs adjustments are made by the BLS based on economic assumptions about the birth and death of businesses (not individuals). Those assumptions are made according to estimates of where the BLS thinks we are in the economic cycle.
The BLS has admitted however, that their model will be wrong at economic turning points. And there is no doubt we are long past an economic turning point.
Here is the pertinent snip from the BLS on Birth/Death Methodology.
* The net birth/death model component figures are unique to each month and exhibit a seasonal pattern that can result in negative adjustments in some months. These models do not attempt to correct for any other potential error sources in the CES estimates such as sampling error or design limitations.
* Note that the net birth/death figures are not seasonally adjusted, and are applied to not seasonally adjusted monthly employment links to determine the final estimate.
* The most significant potential drawback to this or any model-based approach is that time series modeling assumes a predictable continuation of historical patterns and relationships and therefore is likely to have some difficulty producing reliable estimates at economic turning points or during periods when there are sudden changes in trend.
Household Data
In March, the number of persons working part time for economic reasons (sometimes referred to as involuntary part-time workers) climbed by 423,000 to 9.0 million. This category includes persons who would like to work full time but were working part time because their hours had been cut back or because they were unable to find full-time jobs.
Persons Not in the Labor Force
About 2.1 million persons (not seasonally adjusted) were marginally attached to the labor force in March, 754,000 more than a year earlier. These individuals wanted and were available for work and had looked for a job sometime in the prior 12 months. They were not counted as unemployed because they had not searched for work in the 4 weeks preceding the survey.
Among the marginally attached, there were 685,000 discouraged workers in March, up by 284,000 from a year earlier. Discouraged workers are persons not currently looking for work because they believe no jobs are available for them. The other 1.4 million persons marginally attached to the labor force in March had not searched for work in the 4 weeks preceding the survey for reasons such as school attendance or family responsibilities...
Grim Statistics
The official unemployment rate is 8.5% and rising sharply. However, if you start counting all the people that want a job but gave up, all the people with part-time jobs that want a full-time job, all the people who dropped off the unemployment rolls because their unemployment benefits ran out, etc., you get a closer picture of what the unemployment rate is. That number is in the last row labeled U-6.
It reflects how unemployment feels to the average Joe on the street. U-6 is 15.6%. Both U-6 and U-3 (the so called "official" unemployment number) are poised to rise further.
Looking ahead, I expect the service sector to continue to weaken. Mall vacancy rates are rising and a huge contraction in commercial real estate is finally started. There is no driver for jobs and states in forced cutback mode are making matters far worse.
