AI Summary.A study of US private firms finds that a one-standard-deviation rise in a firm's financing shortfall is associated with a 45% higher likelihood of going public. After an initial public offering, disagreement among lenders about a firm's default risk falls, borrowing costs drop by 45 basis points, and debt rises more than 50% relative to comparable firms by year three.

A study of 100k+ private nonfinancial firms (2012–23), including 433 IPOs, suggests listing improves access to debt as well as equity. After listing, lenders’ risk assessments converge and bank borrowing costs fall 45 basis points, controlling for assessed risk.
Do financing shortfalls drive private firms to go public?
Core argument: A one-standard-deviation increase in a US private firm’s financing deficit is associated with a 45% higher likelihood of going public, controlling for size, growth, leverage, investment, and industry–location–time effects.
A one-standard-deviation increase in a firm’s financing deficit is associated with a 45% higher likelihood of going public [controlling for size, growth, leverage, investment, and industry–location–time effects]. Consistent with a reduction in asymmetric information, we find that dispersion in PD [probability of default as perceived by disparate market participations] drops,beginning immediately after the IPO. [Note that] we calculate PD dispersion only for banks present prior to the IPO]. We find that after controlling for these risk assessments, firms’ borrowing costs drop by 45 bps after going public. [controlling for bank–firm and bank–quarter fixed effects]. Figure 7 shows that in the first year, there is a statistically significant drop in leverage of about 4 pp.. However, the point estimate returns to zero by year three. Figure 6 shows that IPO firms increase their debt by more than 50% relative to control firms by year three following the IPO. [An important caveat is that our post-IPO estimates capture both treatment and selection effects].

A Catalyst For The AI Bubble Break— Historically, controlling for valuations, a 1% rise in the share of the market represented by initial public offerings has been associated with roughly a 4% decline in prices. With large artificial-intelligence company listings expected and share issuance exceeding buybacks, equity supply could shift from shrinking about 1% a year to growing near 5%, implying returns roughly 20% below average.

Funding that equity supply requires selling existing holdings, and index rule changes make passive funds forced buyers, pressuring large-cap technology stocks.

AI Summary.The Congressional Budget Office projects that if interest rates run 1.5 percentage points above its economic forecast, deficits would be $6tn larger over 2026–2036, reflecting a $4.9tn rise in net interest costs and $1.1tn in added debt-service costs. Debt held by the public would reach 133.1% of GDP in 2036, 12.9 percentage points above its baseline.

If interest rates rise 150bp above CBO’s current extended baseline over 2026–2036 (which would leave the 10-year Treasury with a mean yield of 5.8% over that period), deficits would be $6T larger over the period.
How much would higher interest rates add to deficits and debt?
Core argument: CBO projects that interest rates 150 basis points above its economic forecast would make deficits a total of $6 trillion larger over the 2026–2036 period than in its baseline projections.
[If] interest rates are 150 basis points higher than those in CBO’s economic forecast—deficits are a total of $6 trillion larger over the 2026–2036 period than they are in the agency’s baseline projections. That increase in deficits is attributable to a $4.9 trillion increase in net interest costs resulting from higher interest rates on the amount of debt in CBO’s baseline projections and a $1.1 trillion increase in debt-service costs. In 2036, debt held by the public reaches 133.1% of GDP—12.9 percentage points more than debt that year in CBO’s baseline projections.

The Budget and Economic Outlook: 2026 to 2036— The Congressional Budget Office projects the federal deficit will grow from $1.9tn (5.8% of GDP) to $3.1tn (6.7%) over a decade, above the 3.8% averaged over the past 50 years, with rising net interest costs driving much of the increase. Federal debt held by the public is projected to rise from 101% to 120% of GDP.
How Might Fiscal Policy Respond to the Rise of Artificial Intelligence?— The Congressional Budget Office estimates that a permanent 0.5 percentage point increase in annual productivity growth would lower publicly held federal debt after 30 years by 39% of GDP, offsetting roughly half the projected rise from 101% of GDP to 175%. Higher revenue and slower spending growth outweigh higher interest costs.

AI accounts for the only positive trend in US construction spending, having risen by 38% since January 2024. Unfortunately the other three main categories are down since then (manufacturing -28%, commercial real estate -13% and residential -6%). That’s why the decline in planned data center projects is something to watch.

Financing the AI Buildout— The authors estimate roughly 57 gigawatts of operating US data center capacity against a planned development pipeline of about 509 gigawatts, which is not a completion forecast since projects may be delayed, scaled back, or abandoned. Their central scenario has 182.8 gigawatts of added capacity becoming operational through 2032, 117.2 gigawatts completed later, and 226.9 gigawatts never completed.
How Much Revenue Does The AI Buildout Need In 2030?— The authors estimate AI capital spending of $560bn in 2026 and, in a high-investment case, $3.5tn of net AI capital in service by 2030, requiring roughly $1.3tn in annual infrastructure revenue once depreciation, operating costs and a 15% return are covered. That implies 7.4x growth from current annualized revenues, with downstream revenues of $1.9–2.6tn.
One Hundred Years in the U.S. Stock Markets— Over a century, U.S. publicly traded stocks generated roughly $91tn in shareholder wealth enhancement, with returns strongly positively skewed and dominated by a relatively small number of high-performing firms. Because most possible outcomes fall below the mean in a skewed distribution, the authors argue financial planning should focus on median outcomes or the full distribution.
AI Summary.France's official retirement age for full benefits was 62 in 2023, versus 67 in Denmark and the US, and its average actual retirement age was the lowest in Western Europe while life expectancy at 65 reaches about 87, two years longer than in the US.
Paul KrugmanKrugman Wonks Out
Date Posted:
The sharp rise in the price of credit default swaps on French government debt implies a 1.2% of default over the next 5 years, which Krugman thinks “is too low” and cautions “France may have crossed the line from too big to fail to too big to save.”
Does France retire earlier than other wealthy countries despite longer lifespans?
Core argument: France’s official retirement age for full benefits was 62 in 2023, compared with 67 in both Denmark and the United States, and its average actual retirement age was the lowest in Western Europe.
France does stand out, even among fiscally troubled nations, in one main way: its persistent inability to get realistic about retirement. The official French retirement age — the age at which workers can collect full benefits — was only 62 in 2023. By comparison, the retirement age in Denmark was 67 (which is also the age in the U.S.). The average actual age of retirement, which is always lower than the statutory age because some people choose to accept reduced benefits, was lower in France than anywhere else in Western Europe. You don’t have to be a conservative to see France’s early retirement as unsustainable, especially given that French life expectancy at age 65 is about 87 years of age, 2 years longer than in the US. France’s reliance on the euro means that it’s all too easy to see how this loss of confidence could turn into an ugly crisis.

AI Summary.Corporate profit margins, long regarded as one of the economy's most reliably mean-reverting series, have risen continuously so far this century.

Since 2000, post-tax corporate profits as a share of GDP have trended upward across cyclical setbacks and are now near an all time high, above their 1929 level.
Have corporate profit margins stopped reverting to the mean?
Core argument: Corporate profits measured in the National Income and Product Accounts take a larger share of the U.S. economy than on the eve of the 1929 Great Crash.
Throughout the 20th century, profit margins were regarded as one of the purest mean-reverting series in the economy. So far this century, however, margins have done nothing but rise. Measured with the National Income and Product Accounts, part of the GDP calculation, profits are currently taking a bigger share of the economy even than on the eve of the Great Crash in 1929. The series comes with a lag, so we can assume the profit share on this basis is comfortably at a record by now.

US Focus: The Effect Of Soaring Profits— US nominal pre-tax corporate profits in the national accounts grew 23% over the past year, a pace not seen outside post-recession spikes since the mid-2000s. Wider margins were the key driver, as domestic profit growth far exceeded the 8% rise in corporate value added, pushing margins near all-time highs while the labor share hit new lows.
The Post‑COVID Decline in the Labor Share— The share of US national income paid to workers fell 1.6 percentage points below its pre-pandemic level, reaching a post-war low. The authors find this decline stems mainly from changes within industries rather than shifts in activity across sectors, following cyclical patterns seen in earlier recessions.
Are US Corporate Profit Margins Too High?— US after-tax non-financial corporate profit margins remain elevated by historical standards, estimated at 7.6% versus a post-1949 high of 8.2%, while employee pay as a share of non-financial corporate gross value added has fallen from 66% to 56%. One argument holds that subdued demographic growth leads companies to prioritize maximizing margins over expanding capacity.

Are inflation and debt worries pushing long-term yields to decades-highs?
Core argument: The 30-year US Treasury yield rose as much as 0.09 percentage points to 5.73%, its highest level since 2002, before easing to 5.66% following a strong 10-year Treasury auction.
A sell-off in US government bonds eased after an auction of 10-year Treasuries drew strong demand in a sign that investors were seeking to lock in the highest yields since the turn of the millennium. US 10-year Treasury yields, a benchmark for borrowing costs in the world’s biggest economy, climbed as high as 5.36% in volatile trading early on Wednesday. But yields fell back sharply after a $39bn auction went smoothly, with the 10-year recently trading at 5.29%. France’s 10-year borrowing costs rose to 4.87%, heading back towards the post-2002 high reached this month, amid persistent worries that the Eurozone’s second-biggest economy was heading for a debt reckoning.
