Ultra-Low Interest Rates Have Diminished Productivity



  • The Cantillon Effect is the uneven benefits of monetary stimulus that advantage some market actors over others.
  • A recent academic paper provides a model showing that ultra-low interest rates have acted as a Cantillon Effect, benefiting industry leaders and diminishing competitiveness.
  • This diminished competitiveness has decreased investment and productivity, thus also curtailing economic growth.
  • Slower economic growth disproportionately hurts the less well-off.
  • Quality factor ETFs are poised to benefit from this continued trend.

In a previous article, I described how corporate profitability is inversely related to the level of interest rates. In other words, low interest rates lead to high corporate profits, and high interest rates lead to low corporate profits.

The following charts do a good job of illustrating this. The first chart (corporate profits after tax divided by GDP) shows a rough V-shape, with the nadir occurring around 1986.

In the second chart, we see an upside-down V-shape, reaching its zenith around 1984.

Compare these charts to one more chart, one that should come as no surprise considering the previous chart - the 10-year Treasury yield:

You can see if you look closely that the 10-year Treasury yield peaked in 1981 at above 15%.

Corporate debt was priced higher following Treasuries during this time, which is what led to the spike in cost of capital. As with many economic shocks, it took time for interest rate changes to ripple through the economy, first pulling up corporate debt yields, and then weighing on profitability as businesses were unable to raise prices fast enough to compensate for increased financing costs.

Now that interest rates have plummeted back down to the ultra-low level enjoyed in the wake of World War II, business profitability has rocketed back up, above even the late 1940s and early 1950s. But not all businesses benefit equally.

The Cantillon Effect

What affects the amount of goods or services that are produced? There are basically three factors: capital, labor, and know-how. These are sometimes called the "factors of production." Without capital, even laborers with the know-how to create products will be unable to realize that creation process. Without labor, capital sits idle. And without technical knowledge or intellectual property, laborers using the existing stock of capital cannot increase their production capacity.

So what happens when money is printed or digitally created in order to stimulate the economy? In theory, this extra injection of cash increases liquidity and greases the gears of the economy, spurring increased production and consumption. But do all market actors benefit from this stimulus the same? At the same time?

No, they do not. It's an oft-repeated (and more or less accurate) truism that inflation is a monetary phenomenon. When the money supply grows faster than market demand for dollars (or interest rates fall lower than market forces of supply and demand would dictate), inflation follows. But when monetary stimulus is effected, prices do not immediately reflect it. Rather, the first recipients of this monetary stimulus benefit more than others, as they have the ability to spend newly created dollars before prices rise to reflect the increase in the money supply.

As the newly created money filters through the economy, prices slowly begin to reflect the reality of an enlarged money stock. Those who are last to receive this new money or take out a loan are worse off, as prices have already risen to reflect the expanded supply of dollars. Those who are worst off are those who personally receive no benefit from the newly created money but still have to pay the higher prices.

(If you ask me, I'd call this a form of redistribution — from the poor to the rich.)

This phenomenon is called the "Cantillon Effect," named after 18th century Irish-French economist Richard Cantillon. It describes this uneven dispersion of new money in the economy. There may be increased production or consumption as a result of monetary stimulus, but only for some at the expense of others.

Increasing the money supply does not increase the supply of capital, labor, or know-how. At best, it increases the financial strength and flexibility of those market actors who are closest to the money spigots while harming those who are furthest from them.

It is a monetary trickle-down effect, and it works about as well as opponents of "trickle-down" economics say that theory works.

A Real-World Example Of The Cantillon Effect

It turns out that lowering interest rates does not affect all businesses equally. Larger companies which have stronger balance sheets and command significant market share benefit more than smaller, newer entrants into the field.

Simcha Barkai of the London Business School finds that:

declines in the interest rate lead to significantly larger gains for dominant firms (defined as the top 5 percent in an industry, with alternative definitions for robustness).

Larger, more established and stabilized firms can borrow for cheaper than their competitors and therefore have a lower cost of capital. A lower cost of capital amounts to a lower hurdle rate for potential investments.

But this has lessened total competitiveness in many industries, as the largest players are able to maximize their size and financial strength as an advantage against smaller, financially weaker competitors. Thus, fewer industries are "contestable" — feasibly open to new competitors entering to claim market share. Barkai writes:

A low interest rate results in low growth because it reduces the fraction of industries that (in steady state) are contestable.

In other words, low interest rates, all else being equal, reduce the total competitiveness of the economy.

As I wrote in the previous article:

With low interest rates, market-leading firms are less incentivized to invest in longterm and risky R&D than they are to go about other methods of maintaining market share such as acquiring smaller, innovative companies, lobbying the government, and buying back corporate shares. But for industry leaders who are typically larger and more stable, the ability to borrow cheaply is disproportionately beneficial.

Lower interest rates benefit market leaders regardless how they use their cost of capital advantage — as long as it results in maintaining their market position.

One recent study corroborates this line of reasoning, concluding that the US business sector has indeed under-invested (in terms of R&D) since 2000 and cited declining competition (due to market competition) as one of the primary culprits.

The Upshot: Eroding Productivity

What is the result of this declining competition? In short, less competition has led to less productivity growth. See, for instance, this chart of YoY productivity growth in the US:

ChartData by YCharts

It looks a bit like a polygraph test, but I would point out that the average from the 1970s through the late 1990s remained quite high. Then, beginning in the early 2000s, the average drops off noticeably - from almost 4% at 2000 to 1.5-2% today.

A January 2019 study from two Princeton economists and one Chicago Booth School economist, entitled "Low Interest Rates, Market Power, and Productivity Growth," substantiates and enriches the above argument. The researchers write:

The existing literature in growth either assumes no supply-side response to declining interest rates, or a positive response driven by an increased incentive to invest in the face of a higher discounted present value of future profits.

But this isn't the case, they say:

We show theoretically that a low interest rate gives industry leaders a strategic advantage over followers, and this advantage becomes more dominant as the interest rate approaches zero. Consequently, as the interest rate declines, market structure becomes more monopolistic, and, for a sufficiently low interest rate, productivity growth slows. . . . A decline in the ten year Treasury yield generates positive excess returns for leaders, and the magnitude of the excess returns rises as the yield approaches zero.

Thus, they conclude, "the effect of lower interest rates on growth in a low interest rate regime can be negative."

The reason is that while both the leader and follower within an industry increase their investment in response to a reduction in interest rates, the increase in investment is always stronger for the leader. As a result, the gap between the leader and follower increases as interest rates decline, making an industry less competitive and more concentrated. When interest rates are already low, this negative effect of lower interest rates on industry competition tends to lower growth and overwhelms the traditional positive effect of lower interest rates on growth.

This rationale goes a long way in explaining the "secular stagnation" that developed countries have experienced in recent decades. This phenomenon is often blamed on demographics, the Great Recession, insufficient fiscal or monetary stimulus, etc. All of these traditional explanations are looking in the wrong direction. They want to see anything but the obvious: the Cantillon Effect is real, and it has been working exactly as envisioned.

This paper introduces the possibility of low interest rates as the common global “factor” that drives the slowdown in productivity growth. . . A reduction in long term interest rates increases market concentration and market power in the model. A fall in the interest rate also makes industry leadership and monopoly power more persistent.

"In short," says a Chicago Booth School article summarizing the paper, "as interest rates fell, rich companies got richer, and the smaller companies got stuck, or worse."

Conclusion And Investor Takeaway

Going forward, with tens of trillions of dollars' worth of global debt already in negative territory and US rates falling, it does not appear as though the current situation is going to reverse anytime soon.

This may not be good for economic growth as a whole, but it may have implications for which kinds of stocks will outperform others over long time periods. Higher quality companies or those with wider economic "moats" (competitive advantages over rivals) will likely remain in dominant positions.

Take a look, then, at ETFs that seek to collect industry leaders with competitive advantages in one basket:

ChartData by YCharts

Notice that international stocks that supposedly wield competitive advantages (purple line above) have performed much more poorly than quality US stocks. It appears that international investors place more trust in US stocks than in the stocks of their home countries, at least in relation to American investors.

The three top-performing ETFs above have each outperformed (albeit slightly) the S&P 500 (SPY) during the current bull market.

Considering the current interest rate situation and the likelihood of additional monetary stimulus to come, these ETFs seem like good candidates for continued outperformance in the future.

Become a “Passive Landlord” with our 8% Yielding Real Estate Portfolio.

My adult life can be broken out into three distinct phases. In my early 20s, I earned a bachelor's degree in Cinema & Media Arts (emphasis in screenwriting), but I hated working in Hollywood. Too much schmoozing and far too much traffic. So, after leaving California, I earned a Master of Fine Arts in Creative Writing from Western State Colorado University. I loved writing fiction, but it didn't pay the bills.

In my mid-20s, I became a real estate agent and gained some very valuable experience in residential and commercial real estate. But my passion for writing never went away.

Now, in my early 30s, I write for Jussi Askola's excellent marketplace service, High Yield Landlord, as well as its sister service, High Yield Investor. I also perform freelance research for a family office that owns and manages over 40 net lease commercial properties in Texas and Arkansas. Writing about finance and investing scratches that creative itch while paying the bills - the best of both worlds.

I'm a Millennial with a long-term horizon and am fascinated with the magic of compound interest and dividend growth investing. I also have an interest in macroeconomic trends, though I am but an amateur in that field.
