"Why bother aping a data series that is not particularly helpful in real time?"

The Big Picture criticizes ADP on job data reports:

"ADP has put together a fairly miserable track record in forecasting BLS job data. This month, they have, once again, revamped their methodology in an attempt to more closely track BLS data, which they claim after the BLS revisions one year later their data will match up.

Why? Why is that goal is even remotely desirable? ( A GOOD POINT. IT SEEMS REDUNDANT. )

ADP has their own proprietary data sources; they track employees (new and existing), they can track payroll dollars (total gains and losses, and per employee changes), off of the actual payroll checks going to employees. Why try to imitate the BLS output each month? ADP can create a very specific set of reports that ARE PURELY DRIVEN BY THEIR OWN PAYROLL RECEIPTS, that stands on its own. ( WHY NOT? )

Why even bother messing around with trying to imitate or forecast BLS data? ( A GOOD QUESTION )

The BLS Non-Farm Payroll numbers are somewhat flawed, subject to massive revisions, and fatally flawed due to how the Birth Death adjustment has been applied.

If ADP wants to contribute something valuable, they should stop trying to forecast BLS, and instead generate their own, proprietary, data driven monthly NFP numbers. ( SEEMS GOOD )

Consider how NFP lags the end of recessions, continuing to be negative long after the recovery begins. Employers often expand output without new hiring( TRUE ): They offer full time employment to part–time workers, and offer overtime to full timers( ESPECIALLY AFTER A DOWNTURN. ). ADP can track that, and capture a real time improvement in the economy long before it shows up in the BLS data. ( WOULDN'T THAT SHOW IN THE PRODUCTIVITY NUMBERS? )

Inquiring minds want to know: Why bother aping a data series that is not particularly helpful in real time?

HI Don,

There is a demand for the ADP service from market participants, as the BLS report is almost impossible to predict. As a trader or portfolio manager, the ADP report may be helpful when making portfolio decisions for the coming BLS report - especially in fixed income.

Clearly, the average person only focuses on the BLS report - if they look at anything besides the unemployment rate at all.

Best, Rebecca

Rebecca,

Thanks for the help, but I do have questions. How does it help if it is so far off? Also, wouldn't it be better for ADP to produce its own report? Wouldn't two reports be better than one? Or, is the BLS the necessary report, and the ADP attempt at mirroring it the real use of the ADP report? Namely, as a bridge for investors until the BLS report comes out? From my perspective, since all measures are flawed, it would be better to have two independent reports to use? But then, I'm not a portfolio manager.My belief is that government measures are tied into their use for government programs, and so are useful, but not necessarily the best measure. The government generally wants a report that is easy to use for things like benefits and budgets.

Take care,

Don

The ADP report is very different than the BLS report, and I think that they should better highlight those differences. The cool thing about the ADP report is that they are using real-time payroll data, rather than survey data about workers that are on payroll (may not necessarily be getting paid), as does the BLS. Furthermore, ADP breaks down their survey by size - small, medium, and large - within broad production sectors, rather than by industry like the BLS does.

They ADP hasn't always done such a poor job of forecasting the BLS report, but perhaps they should better highlight their added value (as stated above), rather than try to forecast the BLS report.

Best, Rebecca
