Multifactor Productivity Growth: A Record High in 2010

Posted on by

US Productivity Growth, Non-farm Business Sector, 1988- 2010

The Republican presidential candidates continue to assert loudly that over-bearing new regulatory burdens under Obama have crippled the American economy and account for the slow recovery from the 2008 collapse.  Mitt Romney, in a policy address at the University of Chicago on March 19 for example (see transcript here), asserted that regulatory burdens (in addition to higher taxes, even though taxes have in fact been cut under Obama), were leading to businesses shutting down and jobs disappearing as “Entrepreneurs decide it’s too risky and too costly to invest and to hire.”

New burdensome regulations, if they were a problem, would reduce productivity.  Yet as this blog has noted previously (see here), productivity growth has in fact been quite good during the Obama period.  The productivity concept normally used for such discussion is simple labor productivity, which measures output (GDP) per unit of labor input (either employment or hours of labor).  This productivity concept is useful in part because it can be estimated as soon as one has an estimate of GDP, i.e. each calendar quarter.  But it is not a measure of pure productivity, as output per unit of labor can rise due to several things, including from increased capital investment (more machinery and equipment, which improves productivity) or from changes in the composition of labor (towards more highly educated, and hence more productive, workers).

Multifactor Productivity (also sometimes called Total Factor Productivity) is a measure of productivity that takes into account increased capital availability and other such factors.   The Bureau of Labor Statistics of the US Department of Labor provides an estimate of it, but because it is more difficult to estimate, it only comes out with a major lag.  On March 21, the BLS issued its estimate for 2010.  Only annual estimates are made.  And while the series only goes back to 1987 (and hence has growth rates only from 1988), it is interesting that while Romney and the other Republicans are complaining of a large increased burden on business from regulations under Obama, the BLS found that multifactor productivity grew faster in 2010 than in any year since they started estimating the series in 1988.

The graph above shows the BLS estimates of multifactor productivity (MFP) growth for 1988 to 2010, for the private non-farm business sector.  MFP grew by 3.5% in 2010, reversing the downward trend seen since 2003 and absolute declines in 2008 and 2009.  As noted, the 3.5% increase in MFP in 2010 is the highest in the history of the series.  If Obama’s regulations were stifling businesses, one would not see such an upward bounce in productivity.  The Republican charge is simply not consistent with the facts.

One should also not jump to the opposite conclusion that the upward bounce in productivity in 2010 can be credited totally to regulatory or other reforms instituted by the Obama administration.  It would be consistent with such reforms improving productivity (i.e. the opposite of what Romney and the Republicans have asserted), but it could be due to other factors also.

The truth is that much of the year to year change in productivity can be accounted for by the business cycle.  When economic output is falling, as it was in 2008 and the first half of 2009, productivity will typically fall (or not grow as much as in normal growth years), as businesses lay off labor only with a lag after they find they cannot sell all of their output.  And in an economic recovery, productivity will rise, as businesses also only start to hire new workers with a lag.  The same happens with business investment (and hence the stock of machinery and equipment and other capital available for use), so that capital is underused as economic output falls in a recession and then is more intensively used at the start of a recovery.  Looking forward, it is likely that MFP growth will not be so high in 2011, and indeed might even be relatively low, as businesses started hiring new workers more aggressively in 2011 as the economic recovery continued (albeit slowly, due to still low demand for what they could produce).  But we will not know for another year, when the BLS issues their estimate for MFP growth in 2011.

The productivity data cannot by itself demonstrate conclusively whether or not the record high growth in productivity in 2010 was primarily due to measures implemented by the Obama administration.  But what we do know is that the data is clearly not consistent with the Republican charge that Obama has imposed huge new regulatory burdens which have stifled productivity.

Weekly Initial Claims for Unemployment Insurance: A Good Report, But Not Yet Where It Needs to Be

Posted on by

Initial claims for unemployment insurance continue to improve, although claims are still somewhat above where they would normally be when the economy is at full employment.  While there is a good deal of noise in the week to week figures, the trend has clearly been an improving one.  But there are concerns that weak US growth, and problems stemming from Europe and elsewhere, could undermine the improvement seen so far.

The data come from this morning’s regular weekly release by the US Department of Labor, and it is helpful to see the figures in the longer term context.  The graph above updates one from my posting of November 20, 2011.  Initial claims for unemployment insurance came to 348,000 in the week ending February 11, far better than the roughly 650,000 per week who were being laid off and filing claims for unemployment insurance when Obama took office.

The initial unemployment claims are still somewhat above, although now fairly close to, the level of around 310,000 to 320,000 per week that one would see when the economy is at close to full employment.  As was discussed in a January 19 posting on this blog on the dynamics of the labor market, there is constant churning in the jobs market, with workers being laid off even when the economy is at full employment.  And as was shown in the second graph in that January 19 posting, layoffs are now close to where they were before the 2008 economic collapse.

But new hires remain (at around 4 million per month) well below where they would be when the economy is operating at full employment (around 5 million per month).  Hence unemployment remains high (8.3%).  Firms have a surfeit of cash in their accounts from very high profits (see posting here), but there is little demand for extra production.  Unfortunately, it is now politically impossible (due to concerted Republican opposition in Congress) for the government to follow the expansionary policy one would need to provide that demand.

So the economy continues to grow, but slowly.  Hence the employment situation has continued to improve, but only slowly.  And there are concerns that the on-going recovery in 2012 remains fragile.  As was noted in a January 27 post, US growth in the fourth quarter of 2011 was largely due to a large increase in inventories.  This is unlikely to continue, and even if inventory growth increases again as much as it did in the fourth quarter (with all else growing as it did in the fourth quarter, although these will of course change), GDP growth would come to only 0.8% at an annual rate.

There are also major concerns arising from Europe.  Europe has been following deliberate austerity policies, and consequently is likely now in recession.  It was announced yesterday that GDP fell in the EU as a whole at a 1.2% annualized rate in the fourth quarter (0.3% at a quarterly rate).  The normal criterion for a recession is for two quarters of such negative growth.  The Greek crisis is also not resolved, and could get much worse.  And there are other global concerns as well, such as the risk that tensions with Iran could escalate and lead to an attempt to close of the Straits of Hormuz, and cause oil prices to skyrocket.

So while the labor market has improved, there are concerns on whether this can be sustained.

Employment Growth in January: Better, but Sustainability is a Concern

Posted on by

The employment report for January, released this morning by the Bureau of Labor Statistics, is a positive report.  But while employment growth is now improving, it is still not rapid enough, and its sustainability is a concern.

As I had noted in a posting on December 5 in this blog, monthly employment growth in the US needs to be in a range of roughly 200 to 250,000 per month for unemployment to fall on a sustainable basis.  One is now starting to see that, with overall employment growth of 203,000 in December and 243,000 in January.  With such growth, the unemployment rate fell from 8.9% in October to 8.7% in November to 8.5% in December and to 8.3% in January.  This is certainly welcome.  But unemployment at 8.3% is still far too high.  In a more robust recovery, one would be seeing monthly employment growth figures of over 300,000.

And the overall employment figures are still being held back by falling employment in government (mostly state and local government, which accounts for 87% of government employment in the US, but there have also been falls in federal employment).  In January, total government employment fell by 14,000, thus partly offsetting the rise in private employment of 257,000, to produce the overall gain of 243,000.

For the past year (January 2011 to January 2012), government employment fell by 276,000.  This has been a significant factor in holding down overall employment growth.  And government employment fell by 230,000 in the year before that (January 2010 to January 2011), and fell by 97,000 in the year before that (January 2009, when Obama was inaugurated, to January 2010), for a total fall in government employment of 603,000 over the three years.  In the three years before Obama took office, government employment rose by 248,000 in 2006, rose by 281,000 in 2007, and rose by 200,000 in 2008, for a total increase of 729,000.

Yet Obama has been repeatedly accused of creating an explosion of government.  (For a more detailed review of what has happened to Federal Government employment alone, see this blog.)  Had total government employment risen by 600,000 rather than fallen by 600,000 since Obama took office, one would have had an extra 1.2 million jobs directly.  Even ignoring any multiplier impact, this by itself would have led to an unemployment rate now of 7.5% rather than 8.3%.  And assuming, conservatively, a multiplier of just two (so that one additional government job leads to one additional private job, to supply the goods to cover the increased personal spending of the now employed government workers), the unemployment rate would now be a more respectable 6.7%.

While the January employment report was positive, one should keep in mind that there are threats on the horizon.  Two to consider:

1)  As noted in a January 27 blog, GDP growth in the fourth quarter of 2011 was only 2.8%, and 70% of this came from the change in the change in private inventories.  Without this inventory change, GDP would have grown by just 0.8%.  For the first quarter of 2012, it is unlikely that private inventories will again go up by so much.  And note that because it is the change in the change in private inventories that is the contribution to GDP growth (see this blog), then should private inventories once again increase by as much as they did in the fourth quarter of 2011, the growth in GDP in the current quarter would only be 0.8% (everything else being equal as in the fourth quarter of 2011, which of course it won’t be).  That is, inventories would have to continue to rise by as much as they did in the fourth quarter of 2011 simply to keep GDP growth at 0.8%.  They are likely to rise by far less, and quite possibly might fall if the high level of inventory accumulation in late 2011 was more than suppliers wanted.  This could then significantly hold back production and GDP growth, and hence employment growth, over the next several months.

2)  Europe continues to be problematic, with the focus on policies (fiscal austerity) which will make the situation worse rather than better.  Europe will certainly be in recession in 2012, and probably already is, and this will hurt the US recovery.

And there are of course other risks, such as, for example, an escalation in tensions with Iran leading to disruption of shipping through the Strait of Hormuz, that could cause oil prices to skyrocket.  There are many such scenarios that one can imagine, so a US recovery is anything but certain.  So while the January employment report was a positive one, there are still reasons to be concerned.
