MMT And Its Fictional Discipline?

That is some crazy talk” – Bill Gates on the topic of MMT

Q4 hedge fund letters, conference, scoops etc

In our article, MMT Sounds Great in Theory… But, we dove into the latest and greatest of economic thinking, Modern Monetary Theory (MMT). This theory is crucially important for investors and citizens to understand as its popularity is spreading like wildfire. The theory promises to be a strong force in the coming election and a challenge to the popular Keynesian policies that are widely adhered to by most governments and central banks.

Free healthcare and higher education, jobs for everyone, living wages and all sorts of other promises are just a few of the benefits that MMT can provide. At least, that is how the theory is being sold. Regardless of the apparent unreasonableness of such promises, it’s not hard to imagine presidential and congressional candidates running and winning on such a “free lunch” economic platform. Bear in mind, this was done with some success in 2016 as Stephanie Kelton, Bernie Sander’s chief economic advisor, is a leading advocate of MMT.

Given the importance of this new thinking, we will analyze various bits and pieces of the theory in the coming months. In this article, we discuss a crucial aspect of the theory, inflation. MMT theory essentially believes the government spending can be funded by printing money. Currently, government spending is funded by debt and not the Fed’s printing press. MMT disciples tell us that when the shackles of debt and deficits are removed, government spending can promote economic growth, full employment and public handouts galore. MMT does, however, have a discipline that regulates spending, and that is inflation.


Inflation is impossible to calculate. Inflation is impossible to calculate. No, that is not a typo. For emphasis, let us put it another way. Inflation is impossible to calculate.

The point that inflation is impossible to calculate cannot be overstated.

Economists will say the Consumer Price Index (CPI), for instance, does a good job of telling us whether prices are rising or falling and to the precision of a tenth of a percent. As background, CPI measures how a select basket of goods changes in price from month to month.

In regards to CPI and its purported accuracy think about these questions:

  • Do the specific goods and amount of goods in the CPI basket match what you buy?
  • Are prices of goods the same in Nevada as they are in Maine?
  • Do you substitute apples for oranges when oranges rise in price?
  • Does a 75-year-old retired couple consume the same basket of goods as a single 20-year-old in college or a 50-year-old couple with three teenagers?
  • Are value hedonic adjustments fair and reflective of the value you receive from the goods? (Hedonic adjustments attempt to change the price of goods based on perceived improvements in value. For instance, the decline in computer prices as measured within CPI is greater than what we observe at the store because they deliver more power today than in the past. We expanded on this concept in the MMT article mentioned earlier.)

We now get personal because this point is crucial. Michael Lebowitz, a partner at Real Investment Advice, is 50 years old, married, with three teenagers. He pays for his own health care and has one kid in college. He lives near Washington D.C. where real estate and many of the goods and services he consumes are more expensive than the national average. CPI, as reported by the BLS, is running annually at +1.9%. Do you think Michael’s personal CPI is only 1.9%? Based on a simple and reliable personal budget analysis, his price index has been running in the double digits for the last few years.

Washington, DC provides one good example as a city, but it is not a leap to say that major metropolitan and urban areas impose a higher cost of living than rural areas. Furthermore, according to the 2010 United States Census, over 71% of the population live in “urbanized areas”, which the Census Bureau defines as “densely developed residential, commercial and other nonresidential areas.” Does measurement of CPI or any other inflation metric properly account for such complexities? How can they?

The bottom line is that inflation varies widely by demographic, region and individual needs and desires and a host of other differences that cannot possibly be accounted for in one number.

That is problem number one with applying a “CPI-for-all” mentality and using it to make important policy decisions.

Inflation Manipulation

There is a bigger and more nefarious problem with inflation measurements and how they can be manipulated. To reiterate, MMT states that government spending and money printing can occur as long as inflation is limited.

If inflation regulates government spending and by default the health of the economy, then won’t leaders, who will do anything to retain their power, suppress inflation readings to allow greater spending?

Sadly, that question is rhetorical. We know the rate of inflation is already being suppressed for political reasons. As an example, the Federal Reserve uses Core CPI, a derivative of CPI that excludes food and energy, as prices on those two components are unusually volatile. They do tend to be volatile, but they are also two of the biggest expenses of the population. That is like measuring a quarterback’s accuracy without considering passes that occur further than ten yards from the line of scrimmage.

As for the government, they routinely take steps to manipulate how CPI and other inflation data are calculated and published.

Before continuing with what some may call a conspiracy theory, we think a little background on the Boskin Commission is appropriate. Per Wikipedia:

The Boskin Commission, formally called the “Advisory Commission to Study the Consumer Price Index”, was appointed by the United States Senate in 1995 to study possible bias in the computation of the Consumer Price Index (CPI), which is used to measure inflation in the United States. Its final report, titled “Toward A More Accurate Measure Of The Cost Of Living” and issued on December 4, 1996, concluded that the CPI overstated inflation by about 1.1 percentage points per year in 1996 and about 1.3 percentage points prior to 1996.

The report was important because inflation, as calculated by the Bureau of Labor Statistics, is used to index the annual payment increases in Social Security and other retirement and compensation programs. This implied that the federal budget had increased by more than it should have, and that projections of future budget deficits were too large. The original report calculated that the overstatement of inflation would add $148 billion to the deficit and $691 billion to the national debt by 2006.

The Boskin Commission was formed, and their recommendations enacted, to reduce reported inflation. Inflation is costly to the government due to higher borrowing rates, cost of living wage adjustments, and social security expenses. Said differently, by lowering measured inflation they reduced governmental expenses and allowed for more spending. Our opinion on the government’s motives is not a result of our cynical nature; it is based on the illogic of some of the adjustments that have occurred since the commission was formed.

The best example to highlight this is housing prices and their contribution to CPI. In 1998, the Bureau of Labor Statistics (BLS) changed the way they calculated real estate prices within CPI. The BLS replaced an index based on actual home prices with what is now called owner’s equivalent rent (OER). OER is a rental equivalence which calculates the price at which an owned house would rent. It is important to note that rents were then and continue to be a part of the CPI calculation.

The graph below compares the compounded growth rates of the OER index and the widely recognized leader in home price indexing, Case-Shiller U.S. National Home Price Index.

It is clear from the graph that OER is a great substitute for actual home prices if the goal is to reduce reported inflation. However, if you are a citizen and in the market for a house, OER represents wishful thinking.

Based on the data above, CPI has been suppressed by an average of 0.40% per year since 1998 due to the OER calculation. That may not seem material, but this one modification accounts for 20% of the CPI growth over the period.

Even more concerning, the graph below shows that OER understates CPI by much more than 0.40% when the decline in house prices during the financial crisis is excluded. Since the crisis, OER has underestimated CPI by 0.75% annually, meaning that a truer inflation rate over the period from 2010 to current was 2.37% not 1.62%. Annual compounding implies CPI understated the rate of inflation by approximately 7%.

To put a final point on MMT and home prices, consider the following: If house prices in California are rising rapidly while falling in New York, should the same fiscal and monetary policy be applied to both situations? MMT would benefit both New York and California but is that what is truly best for Californians, a state notorious for pricing many out of the housing market? In either case, those most severely impacted are the lower and middle classes struggling to maintain their standard of living.


The problems described above are symptomatic. In this article we only touched on a few of the flaws with the government’s preferred inflation calculation and how it is being manipulated. There are a plethora of other adjustments that are made to adjust inflation to accommodate the preferences of policy-makers. Given the relative ease with which inflation can be hidden, we should assume politicians, especially those that embrace MMT, will lobby for more “adjustments” when inflation rises and threatens their campaign promises. Those promises are, after all, the basis upon which they assume power.
