The long-term downward trend for working teens continued in August 2026. The month saw the overall, seasonally adjusted number of teens Age 16-19 counted as having jobs come in at 5,373,000. While just 7,000 less than in July, that figure is 487,000 below the May 2024 peak.

Breaking the working teen demographic down into younger (Age 16-17) and older (Age 18-19) parts, the number of younger teens with jobs increased month-over-month to a seasonally adjusted 1,856,000, which is 505,000 below its peak from December 2022. Older teens with jobs however saw their seasonally adjusted number decline 95,000 from their level in July to 3,499,000, some 302,000 below their recent February 2025 peak.

Looking at the employed-to-population ratio of the working teen demographics, older teens still come out on top, with 41% of the Age 18-19 population employed, which is down from the December 2025 peak of 45.8%. Younger teens however have a bigger decline from their April 2022 employed-to-population percentage peak of 25.5%, dropping to 20.7% as of August 2026. This latter change is nearly equivalent to going from one in four teens Age 16-17 having jobs in April 2022 to just one in five as of August 2026.

The following pair of charts depicts the rise and fall of teen employment from January 2021 through August 2026.

Each of the data series shown in these charts are subjected to their own seasonal adjustment, which is why the employment numbers for the Age 16-17 portion of the teen population and the Age 18-19 portion won't necessarily add up to the figures indicated for the whole working Age 16-19 population.

The final week of summer saw the S&P 500 (Index: SPX) close out the week at 7,718.60, slightly up over the preceding week's close and one percent below its 13 August 2026 record high.

As expected, investors focused on the upcoming quarter of 2026-Q4 in setting stock prices. The future quarter has become the focus because of the Fed's ongoing "will they or won't they hike rates during the quarter" drama.

Speaking of which, the CME Group's FedWatch Tool projects a 59% probability the Fed will hike the Federal Funds Rate by a quarter percent on 16 September (2026-Q3), with a little under 41% chance of holding at its current target range of 3.50-3.75%. The big change from the previous week however is that the FedWatch Tool now projects the Fed will delay its next quarter point rate hike until 27 January (2027-Q1), although it still gives a 39% probability of an earlier rate hike on 8 December (2026-Q4).

The continuing uncertainty provides investors with an incentive to set their attention on 2026-Q4. The latest update of the alternative futures chart shows the S&P 500's trajectory remains consistent with the approximate level the dividend futures-based model would project for it provided investors focus their forward-looking attention upon 2026-Q4.

The headlines out of Japan suggest the recent rising yields of U.S. Treasuries have a "made in Japan" element to them. This factor may be significant because they would have an effect on the U.S. stock market, with higher yields depressing stock prices because of the resulting higher cost of debt. The effect would be most pronounced on firms that are looking to utilize significant debt financing to support their growth.

The Atlanta Fed's GDPNow tool anticipates +4.7% real GDP growth for the U.S. economy in 2026-Q3, ticking up from the +4.6% annualized growth it projected a week earlier.

04 September 2026

We first wrote about Hauser's Law in 2009. At the time, we described it as "one of the stranger phenomenons in economic data". The law itself was proposed by W. Kurt Hauser in 1993, who observed:

No matter what the tax rates have been, in postwar America tax revenues have remained at about 19.5% of GDP.

In 2009, we found total tax collections the U.S. government averaged 17.8% of GDP in the years from 1946 through 2008, with a standard deviation of 1.2% of GDP. Six years later, we revisited it once again and found that while the standard deviation was the same, average total tax collections from 1946 through 2018 was lowered to 16.8% of GDP because of 2013's comprehensive revision of GDP that significantly boosted historic GDP estimates after the basic GDP formula was redefined.

Seven years later, we're revisiting the historic data once again to see if it still holds. Spoiler alert: it does!

Here's a triple-set of charts to show off Hauser's Law in action!

Hauser's Law in Action: 1946-2025

Since we're now spanning 80 years worth of data, during which the U.S.' maximum income tax rate has ranged between 28% and 92% of income, we confirm once again that the U.S. government's total tax collections have averaged 16.8% with a standard deviation of 1.2% of GDP from 1946 through 2025. If you know your normal distribution bell curve from statistics, that means over 99% of the U.S. government's total tax collections from 1946 through 2026 would be expected to fall between 13.2% and 20.4% of GDP, which they have.

The pattern also holds true for U.S. personal income tax collections, although here, the average is 7.7% of GDP and the standard deviation is 0.8% of GDP.

What all these numbers mean is that the U.S. government's tax collections have been remarkably stable as a percent of GDP, or the national income, over the last eight decades, regardless of how the top income tax rate has been set. We think that represents a political equilibrium, especially as higher rates of tax collections have not been able to be sustained.

There are just four periods where tax collections rose more than one standard deviation above the mean level, none of which proved to be sustainable.

  1. In 1968, the Democratic U.S. Congress and President Lyndon Johnson passed a shock 10% income surtax that took effect in mid-year, spiking the top tax rate from 70% to 77% and increasing the amount collected from top income tax earners by an additional 10%. Coupled with a spike in inflation, for which personal income taxes were not adjusted to compensate, this tax hike led to outsize income tax collections in that year.
  2. The sustained high inflation of 1978 (7.62%), 1979 (11.22%), 1980 (13.58%) and 1981 (10.35%) led to higher tax collections through bracket creep, as income tax brackets in the U.S. were not adjusted for inflation until 1985 as part of President Ronald Reagan's first term Economic Recovery Tax Act.
  3. Beginning in April 1997, a cut in the capital gains tax rate caused the Dot Com Stock Market Bubble to being inflating. As it expanded, the bubble minted a large number of new millionaires as investors swarmed to participate in Internet and "tech" company initial public offerings or private capital ventures, which in turn, inflated personal income tax collections. Unfortunately, like the vaporware produced by many of the companies that sprang up to exploit the investor buying frenzy, the illusion of prosperity could not be sustained and tax collections crashed with the incomes of the Internet titans in the bursting of the bubble, leading to the recession that followed. It eventually came to an end in 2003 after the capital gains tax rate was increased to be equal to the dividend tax rate once again.
  4. In 2022, tax collections spiked with the recovery from the coronavirus pandemic after government-mandated lockdowns and restrictions on businesses were lifted.

There's one final piece of the puzzle we haven't tackled, and that's why the U.S. national debt has grown so large even as federal tax collections have been so relatively stable. Here we find three factors that have contributed to its growth:

  1. The launch of Medicare in 1965 coincides with a period in which government spending no longer drops below the long-term average of tax collections. Before Medicare was passed into law, government spending only surged above that level when wars were fought, dropping back to pre-war levels after they ended. World War 2 is a classic example, with its drawdown in spending taking place in the years after it ended in 1945. The 1980s Cold War defense buildup also shows the same pattern, with spending returning to pre-buildup levels as a percent of GDP in the 1990s as a peace dividend.
  2. The Great Financial Crisis of 2008 led to massive bailouts by the U.S. government. Even though that crisis ended, spending failed to return to its pre-crisis level because President Obama's Affordable Care Act permanently inflated the government's spending from 2014 onward.
  3. The Coronavirus Pandemic of 2020 led to massive government subsidies to offset the impact of the extreme economic disruption caused by state and local government lockdowns. However, two Biden administration initiatives combined to permanently inflate government spending above their pre-crisis levels: the American Recovery Act with its inflationary impact and the cynically-named Inflation Reduction Act that further boosted spending. These two initiatives kept government spending elevated at levels far above what the U.S. government can reasonably expect to collect in taxes based on the last 80 years of experience.

And that, in a nutshell, is why the U.S. government has gone from running mostly balanced budgets in the years before 1965 to running consistently in the red in the years since with few exceptions. The upward ratcheting of government spending in the years since 1965, and particularly since 2008 to levels far above what the U.S. government is capable of sustaining through its stable tax collections is why the national debt has grown to exceed $40 trillion.

The median price of new homes sold in the United States paid by their buyers is declining.

Incentives provided by homebuilders to entice sales is offsetting an increase in mortgage rates in recent months, improving the affordability of new homes. So much so that new homes have become relatively more affordable than existing homes.

Here are the three numbers that define how affordable a new home is for a typical American household in July 2026 and how they've changed from the values we reported for May 2026:

  • Median new home sale price: $393,800 (decrease of $31,100)
  • Median household income: $88,150 (increase of $504)
  • Average 30-year conventional fixed mortgage rate: 6.54% (increase of 0.10%)

Assuming a 0% down payment, a new home sold in July 2026 at the nation's median sale would have a mortgage payment that consumes 34% of the income earned by a household at the exact middle of the U.S. spectrum of income. The following chart reveals the typical new home sold in the U.S. moved to fall within the affordable reach of the typical American household during July 2026:

Mortgage Payment for a Median New Home as a Percentage of Median Household Income, January 2000 - July 2026

The relative affordability thresholds indicated on the chart are defined by the 28/36 rule that mortgage lenders traditionally use to determine whether to extend a mortgage to new home buyers. Here, a monthly mortgage payment that consumes more than 36% of a household's income means that the median new home sold is fully outside the affordable reach of a household earning the median income, even if it has no other debts. At the other end of the rule, a mortgage that does not exceed 28% of a household's income is considered affordable even with average levels of other kinds of debt.

July 2026's relative affordability level falls between these two levels, but nearer the upper end, which means a new home is affordable for a household earning the nation's median household income provided it maintains a low level of other kinds of debt.

The S&P 500 (Index: SPX) rebounded back above its mean trend in August 2026 after briefly breaking below it.

Through the end of trading on Monday, 31 August 2026, the index' value was just slightly below its its trailing 20-day moving average. Meanwhile, the moving average itself was about 96 points (or about 1%) above the level the mean trend trajectory the index has established during its current period of relative order, which has largely held in the 32 months since 31 December 2023.

The following chart visualizes the relationship between the value of the S&P 500 and its underlying trailing year dividends per share from 29 December 2023 through 31 August 2026:
