The Outcome of Income

October 13th, 2013

“Use words not fists” a parent might say to a child.  For the second weekend during the government show down – I mean shut down, the children – er, representatives – in Washington have taken that to heart.  In a contest of dueling podiums, members of each party in both houses of Congress assure the public that their party is the reasonable one.  On Thursday, the market shot up on the news that – no, not a deal – but the likelihood that the two parties might talk to each other instead of mouthing platitudes and principles at their separate podiums.  About three weeks ago, speculative talk of a government shut down began to surface and where was the market after Friday’s close?  Back where it started three weeks ago and just 1.5% below the high on September 19th.

 In the Washington Irving tale, Rip Van Winkle fell asleep for twenty years only to wake up to a new United States of America.  In this version of the tale, an investor goes to sleep for three weeks, wakes up and there’s a whole new United States of Closed For Remodeling.  In a townhome association I belonged to many years ago, the tenants argued for several months over the choice of roofing contractor, color and style of roof for the townhomes.  A large Federal government may take a while longer.   In fact, it has been years since the Congress passed an actual budget.  The Treasury department used up the debt limit last May and has been running on fumes since then, grateful that the housing loan agencies Fannie Mae and Freddie Mac have been paying back some of the cash they “borrowed” from the taxpayers a few years back.

Because of the shut down there have been few government reports.  Commodities traders have been buying and selling in the dark,  guesstimating what the weekly and monthly government reports on the sales and production of corn and other commodities would have been if there had been an actual report.  We can only hope that traders have been fairly accurate.  If there are some notable surprises, duck.

There have been some private reports, one of them the monthly manufacturing and services reports from the Institute for Supply Management (ISM).  I updated the combined weighted index (CWI) that I have been showing the past few months.  Unlike the environment during the August 2011 budget negotiations, business activity shows strength this year and the resilience of the S&P500 index reflects that underlying strength.  Although 10 of 14 trading days were down, the index lost only about 4% from the recent high.

The CWI has been in expansion territory since the summer of 2009, which coincided with the NBER’s official call of the recession’s end.  You’ll notice that there is a rolling wave like movement to the index since then, an ebb and flow of strong and not so strong growth.  Since this is a coincident indicator of the fundamental strengths in the economy, it might not be a good predictor of short term market swings but has been a reliable predictor for the longer term investor.   Despite the recent highs in the market index, the market has been in a downtrend since the highs of thirteen years ago.  It is approaching the high set in 2007, a sign of renewed optimism.

The Federal Reserve recently posted up Census Bureau median household – not individual – income figures for the past thirty years.  Continuing on our theme from last week – the story we tell depends on how we adjust for inflation.  In this case, neither story is particularly cheerful.  Median household income adjusted for inflation using the Personal Consumption Expenditure measure has fallen  to 1998 levels, declining 7% from 2007 levels.

In 1983, the Bureau of Labor Statistics changed their methodology for computing the cost of owning a home, or owner equivalent rent.  Over the years, some economists and financial writers have made the case that the official measure of inflation, the CPI, overstates inflation.  This tells an even bleaker story: a decline of almost 9% from 2007 levels, an annual growth rate over 28 years  of just 1/4% per year.

Now, let’s compare the two.  Does the CPI overstate income by 5% or does the PCE Deflator understate inflation by the same amount?

The methodology influences many people in this country, from seniors on Social Security to working people who rely on cost of living increases.  Yet there will be more debate about whether the manager of a baseball team should put in a fastball pitcher who sometimes struggles with accuracy or go with a pitcher who throws less hard but has good location and change up.  There are political consultants who spend late night hours trying to figure out how to present the problem to the public so that they can understand it and get passionate about it.

The slow growth in household incomes arises because there is a greater supply of people who want work than employers offering work that people can or want to do.  Slow growth in the economy means less demand for labor, which puts downward pressure on the wages that workers can demand.  Smoothing the quarterly percent change in GDP growth for the past thirty years gives a clear picture of this less than robust growth.

While that may be the chief reason for slow income growth, the negative real interest rate of the past five years has played some role, I think.  When the economy is in a recessionary funk,  the Federal Reserve keeps the interest rate low to spur growth.  In the past two recessions, the Fed kept interest rates low for a considerable period of time after GDP growth began to rise.  Now it is easy to look in the rear view mirror at GDP growth, which is revised several times and may be revised again a year later as more information becomes available.  The Federal Reserve has to guess what the growth is and lately they have been overestimating the growth in the economy.

As long as the Fed keeps interest rates low, banks can make easy, safe profits in the spread between buying Treasury bonds and borrowing from the Fed and other banks.  There is less incentive for banks to take the additional risk of investing in business loans.  Although climbing up from the trough of several years ago, business loans in real dollars are still below the levels of mid 2008.

During the past twenty-five years, the rise and fall of commercial loans has become more pronounced.  Have the banks become that much more cautious at each recession, are businesses circling the wagons at the first hint of a downturn, and what part do low interest rates play?

This past week President Obama confirmed his pick of Janet Yellen as the new chairwoman of the Federal Reserve.  Larry Summers had been Mr. Obama’s first choice but Summers withdrew after learning that he would have a difficult confirmation process.  Although very smart, Summers is not a concensus builder.  Many in Congress and the market preferred Yellen to Summers.  Ms. Yellen takes a dovish stance, meaning that she is likely to further the current policy of low interest rates for the near future.  A cautious investor might want to rethink rolling over that 5 year CD that comes up for renewal in the next few months.  Rates are currently 1.5 – 2%, so that after inflation an investor is losing a little money.

Employment and Government Shut Down

Earlier this past week there were rumors that, due to the government shut down,  the Bureau of Labor Statistics (BLS) might not release the monthly employment report on Friday.  The employment report is probably the foremost key indicator that guides stock and bond market action as well as a prime metric used by the Federal Reserve in the determination of future monetary policy. On Thursday, the BLS confirmed that they would not release the report, which prompted a drop in the stock market, followed by an almost equal rise over the next day.

On Wednesday, ADP released a tepid 166,000 estimate of net job gains for September accompanied by a downward revision of their August estimate.  On Thursday, the weekly report of new unemployment claims held no surprise.  Traders probably figured that they had enough information to guesstimate the BLS number of net job gains – tepid growth a bit above the 150,000 needed to keep up with population growth.  In short, there was less likelihood that the Federal Reserve would be tapering their QE program before the end of the year.

So this is a good opportunity to take a look at some historical employment trends.  Measuring wage growth and inflation adjustments to wages is a complex task, far more complex than the gentle reader wants to delve into.  Labor economists crunch a lot of regional employment data gathered by the BLS.  Whenever there is a wealth of data, there is also a wealth of ways to treat that data, which data to focus on, etc.  Some economists focus on median compensation.  The median represents the middle, i.e. 50% of workers make more than the median, 50% make less.

In a 2011 paper published by the Economic Policy Institute (EPI), author Lawrence Mishel states  “Between 1973 and 2011, the median worker’s real hourly compensation (which includes wages and benefits) rose just 10.7 percent.”

“Real” means inflation adjusted but there are different methods used to calculate inflation.  One method, the Consumer Price Index, or CPI, has been changed over the years, making it difficult to make comparisons of data.

For a longer term perspective into the controversy over measurement, let’s turn to a graph of real output and total compensation per hour worked for the business sector.  Here we see a narrowing between compensation and output until output crosses above compensation in the mid-2000s.

The flattening of compensation growth is shown when we focus on the past twenty years.

But the hourly data seemingly contradicts the claim that there has been only an 11% increase in real compensation over the past forty years.  Looks like the total compensation of all workers has risen about 40% or more in the past forty years.  How can the median growth be so far below the total?  To understand that, a reader would have to examine the data sources behind the claim.  We might find that median weekly, not hourly, compensation has risen only 11%.  This could be due to more part time workers, or the rising percentage of women in the labor force who generally work fewer hours than men. What we do know is that a competent economist can find or crunch the data to prove his or her point.

The ability to work empirical magic with data often leads to contradictory claims by noteworthy economists.  The contentiousness of the discussion among economists baffles the intelligent reader.

Let’s return to that bugaboo mentioned earlier: measuring inflation. Twenty years ago, economists Brian Bosworth and George Perry noted the trending gap between output and productivity: “In an economy where real wage growth has paralleled the rise in productivity over the long run, this apparent divergence implies that the benefits of increased productivity have not been distributed in the expected way over the past two decades.”  A chart from their paper illustrates the trend.

A notable trend in the numbers is the steep rise of employee taxes and benefits, or non-wage employer costs.  Economists or politicians sometimes point to the decline in the real hourly wage over the past forty years, without bothering to note the growing non-wage costs of employment, a convenient omission.

Bosworth and Perry document problems and changes in measuring inflation in both consumption and output but noted that “the prices that workers pay as consumers have been rising significantly more rapidly than the prices of the products they produce.”  Further analysis by the authors shows that the wage growth in that twenty year period 1973 – 1993 did not flatten till after 1983.  They conclude that the major reason for the divergence is the difference between how inflation was measured before and after 1983. The authors recommended the use of a Personal Consumption Expenditure (PCE) deflator instead of the CPI, which overstates inflation relative to output.

Let’s look at wage growth over the past twelve years using two methods to see the difference.  The BLS calculates real wage growth using the CPI-U inflation index (Source).  Here is a graph from their data.

Now let’s use the PCE deflator to get a slightly different picture of the same Employment Cost Index.

Now let’s compare the two.

They tell two different stories.  Using the CPI inflation adjustment, the blue line, I could tell a story that wage growth has stagnated over the past ten years.  Using the PCE inflation adjustment, I could tell a story that wage growth has stagnated since the financial crisis.

Now imagine a politician who wants to bash the policies of former President George Bush and exalt the policies of the current administration.  That politician would use the blue line to tell the story of how the Bush Administration undercut the wages of American workers and that this led to the worst recession since the Great Depression.

On the other hand, if a politician wanted to criticize the Obama administration, she would point to the red line.  Worker’s wages grew during the Bush years.  Since Obama took office, wages have stagnated, indicating that Obama’s policies are hurting American workers.

Thus a dense and complicated argument on how to measure inflation becomes a talking point for a politician.  Even worse, noteworthy and popular economists who understand the difficulties of measuring both employment and inflation choose one line or the other to tell a simple story based on their own bias.

During this ongoing government shut down, we will hear a lot of spin and invective.  The profusion of TV, radio and internet media sources ensures that anyone can choose exactly – to a ‘T’ – the version of reality that they want to hear.  Of course, our sources and opinions are unbiased and perfectly reasonable.  But can you believe what the other side is saying?  Boy, are they crazy!
