H-1B visa access drives startup success: +1 std-dev in lottery wins boosts funding probability +4.3pts (+10% from baseline). Data confirms skilled immigration’s impact on entrepreneurial outcomes

Firms with higher H-1B visa lottery win rates experience significant positive outcomes, highlighting the critical role of skilled foreign labor in entrepreneurial success. A one standard deviation increase in win rate correlates with a 4.3 percentage point rise in the likelihood of receiving subsequent external funding, a 10% increase from the baseline. Additionally, it leads to a 2.9 percentage point increase in successful exits over five years, a 19% rise from the baseline exit rate. The probability of an IPO also increases by 1.5 percentage points, a 23% boost from the baseline. Furthermore, firms see a 4.8% increase in patents and a 3.8% rise in patent citations, underscoring the innovation benefits of skilled foreign workers. These findings suggest that enhanced visa access could yield substantial economic advantages for start-ups.

A one standard deviation increase in a firm's H-1B lottery win rate is associated with a 4.3 percentage point higher likelihood of receiving subsequent external funding, a 10% rise from the baseline.
A one standard deviation increase in H-1B win rate corresponds to a 2.9 percentage point rise in successful exits over five years, 19% above the baseline exit rate, and a 1.5 percentage point rise in IPO probability, 23% above baseline.
Firms with higher H-1B lottery win rates show a 4.8% increase in patents and a 3.8% rise in patent citations, suggesting that expanded visa access could benefit start-ups.

New NBER study using a natural experiment suggests talent is limiting constraint. Paper looks at 1,900 startups, majority of which are in high technology fields who applied for the H-1B lottery in 2008, 2009, 2014, and 2015, when H-1B visas were allocated to employers by lottery as demand exceeded the federal cap. Prior to lottery, all the firms had completed at least one round of external financing and none had gone public. They found winning lottery and significant effects out outcomes. Note they do assume that"...The key identification assumption for our results is that a company’s H-1B lottery win rate is exogenous to the quality of the firm and its prospects..."(lottery is computer generated) so talent is not correlated but causative of success.

"....In the U.S., firms can apply for H-1B visas that allow high-skill foreign workers to enter the U.S. There is a fixed quota of H-1B visas available to for-profit firms, and when the number of applications exceeds the quota the U.S. government holds a lottery that assigns H-1B visas based on computer-generated pseudo-random numbers. The outcome of these H-1B visa lotteries provides exogenous, random variation in firms’ access to skilled foreign workers. In this paper, we examine a sample of start-up firms that applied for H-1B visas, and compare outcomes based on the firms’ win rate in the H-1B lotteries.... We find that a firm’s win rate in the H-1B visa lottery is strongly related to the firm’s outcomes over the following three years.Relative to ex ante similar firms that also applied for H-1B visas, firms with higher win rates in the lottery are more likely to receive additional external funding and have an IPO or be acquired. Firms with higher win rates also become more likely to secure funding from a highly reputable VC, receive more patents, and more patent citations. Overall, the results show that access to skilled foreign workers has a strong positive effect on firm-level measures of success...... For example, a one standard deviation increase in the win rate is associated with a 4.3 percentage point increase in the likelihood that the firm receives subsequent external funding (a 10% increase relative to the baseline funding rate). Strikingly, the magnitude of this effect is little changed by the inclusion of controls or various fixed effects, indicating that the outcome of H-1B visa lotteries is indeed random and uncorrelated with observable firm characteristics.... For example, a one standard deviation increase in the win rate is associated with a 2.9 percentage point increase in the probability of a successful exit over a five-year period following the lottery, representing a 19% increase relative to the baseline exit rate..... For example, a one standard deviation increase in the win rate is associated with a 1.5 percentage point increase in the probability of an IPO, representing a 23% increase relative to the baseline IPO rate over a five-year window following the lottery.... For example, a one standard deviation increase in the win rate is associated with a 4.8% increase in the number of patents and a 3.8% in the number of adjusted patent citations. These results suggest that highly skilled foreign workers contribute to the innovation success of start-up firms.....The results show that access to skilled foreign workers leads to improved funding and patenting outcomes for start-up firms, suggesting that improved visa access for such firms could generate significant economic benefits....."

The College Wage Premium in the Generative AI Era

Is Database:: Database

The college wage premium flattened in the mid-2010s and has fallen ~8% since 2022. The authors argue that this compression reflects a broad decline in the returns to formal schooling, rather than a decline in the upper tail.

After expanding for four decades, the U.S. college wage premium [dropped] sharply from 0.626 in 2022 to 0.575 in 2026. Current Population Survey data through 2026 implies an unprecedented drop in relative demand for college labor—the first sustained negative relative demand growth. Post-2022 wage growth slowed disproportionately in high-exposure occupations, which employ a disproportionate share of college graduates. By 2026, going from zero occupational AI exposure to full exposure had a negative effect on wages of−0.086. Combined with the college–non-college exposure gap, this mechanism accounts for roughly 28% of the total drop in the college wage premium from 2022 to 2026. While non-causal, these patterns indicate that task displacement in AI-exposed white-collar occupations plays a quantitatively meaningful role in the recent compression of the aggregate skill premium.

The AI Re-Acceleration That Wasn’t

Kedrosky argues AI capabilities continue to improve, but “the full composite data shows flattening relative gains, not acceleration…rolling relative model gains have fallen from their 2024 peak, while model dispersion has narrowed sharply.”

Using all Epoch’s Capabilities Index observations, and controlling for developer and model family, there is no statistically significant breakpoint. A piecewise model—which splits the series into intervals and applies a sub-function to each segment—does not improve on a purely linear trend: p = 0.615, The estimated change in slope has a confidence interval of -8.4 to +23.4 points per year. In short, the maths shows there is no model acceleration, contrary to claims, and as expected. The result comes from selecting frontier observations only, choosing a breakpoint, ignoring variance collapse, and fitting separate lines on either side.

The AI Trade Is Losing One of Its Key Signals

The Silicon Data LLM Token Expenditure Index, which tracks AI token prices, is down ~20% from its recent peak in May. The metric is a rough “proxy for marginal willingness to pay.”

A softer index doesn’t mean AI is getting cheaper. The gauge blends prices and usage, meaning a dip can imply very different scenarios: either list prices are falling, or demand is shifting toward cheaper models. It could also point to a genuine softening in what buyers are prepared to shoulder. Each of these possibilities carries different implications. Let’s start with a benign read: While token prices have collapsed more than 90% since 2023, total spend has roughly doubled since last year. Cheaper tokens have expanded the market. This means that an index pause is simply digestion, while demand is real and capex is money well spent. The bull case for Nvidia rests here. Now for the interpretation that’s keeping people up at night: Bears warn that sustained weakness in the index could end the trade that saw nearly the entire AI cohort rally hard this cycle. It’s token spending that justifies the next capex order, and the bill is already looking stretched. Allianz Research said there’s nearly a 46% growth gap between AI investment and sales. That’s worse than the 32% divergence measured during the 2001 telecom bust.

The Age Of The Solopreneur

New US business applications have surged since late 2024, driven mainly by “likely nonemployer” filings representing “solopreneurs” rather than businesses expected to hire. Data suggest AI may be enabling this by filling capability gaps without hiring.

While the recent surge in US business formation is not reflected in high-propensity applications, the evidence points toward a structural increase in genuine small business activity over 2025 and 2026, driven by solopreneurs. Preliminary evidence of growth in AI tool usage and solopreneur growth in high-AI-adoption sectors suggests that advances in AI are responsible for a meaningful portion of this growth. We believe AI is lowering barriers to business formation and growth by expanding the capabilities of solopreneurs, further improving tools and platforms that cater to new businesses, and creating a new set of opportunities for entrepreneurs to pursue. Whether the magnitude of this effect is as large as the most optimistic readings of the data suggest remains to be seen, but we believe we might be in the early innings of a fundamental acceleration in business formation—which could have ripple effects throughout the economy.

Chart of the Day: Small Models are Closing the Gap to Frontier AI

Paul Kedrosky Applied Complexity

Date Posted:: June 3, 2026
Is Database:: Database

Small models have increasingly closed the performance gap with frontier models. To Kedrosky, this implies “edge compute becomes real,” which in turn, at the margin, means reduced relative demand for data center-based versus local compute.

A quiet story in AI isn't that large models keep getting better, it's that small ones are catching up quickly. In 2022, reaching 60% on MMLU, a test of academic reasoning, required a 540-billion-parameter model. By 2024, a 3.8-billion-parameter model hit the same threshold — a 142-fold parameter reduction in two years. The direction is clear, and the implications are wide-ranging. Edge compute becomes real. Models that fit on a phone or a sensor don't need a data center. Inference shifts from hyperscaler to device, which is a different supply chain and a different competitive moat than anyone has built for. The data center API business model has a half-life. If a fine-tuned 7B model running locally can handle 80% of enterprise use cases, the case for paying per-token to a cloud provider shrinks fast. The most exposed providers are those whose moats are model quality rather than distribution, i.e., the capex-heavy frontier models. Compute becomes less scarce.

Challenging the Narrative of European Decline, Continued

In 2021 prices, per capita GDP in the Euro area is falling relative to that of the US, but the opposite is true if one takes into account the benefits to Europe from falling tech prices. “The big benefits of IT come from applying it, [not] creating it.”

Let’s start by looking at GDP per capita in Europe (actually the euro area) as a percentage of GDP per capita in the US. If we do this using constant prices — the World Bank uses 2021 prices — we get the line in Chart 1 labeled “2021 prices.” This line shows Europe falling behind over the past 25 years. If, however, we simply use prices in each given year, we get the line labeled “PPP,” which shows Europe gaining on the US. We get a similar picture if we look at GDP per worker-hour, where the black line is calculated using 2021 prices and the blue line is calculated using PPP. IT progress is passed on to all consumers via lower prices. The big benefits of IT come from applying it, rather than creating it. And as I’ve tried to show, the data show Europe holding its own in the relative value of the goods it produces, indicating that European economies are doing fine when it comes to applying technological advances. What should worry Europe, instead, are the geopolitical implications of US/Chinese leadership in advanced technology. The risk of being cut off from strategically important technologies, once minimal, is now very real. And that risk, rather than misleading numbers about trends in real GDP per worker hour, is what should concern European policymakers.

Takeaways by Macro Roundup^® AI

Euro-area GDP per capita relative to the US declines over the past 25 years when measured in constant 2021 prices, as the World Bank does, but rises when measured at each year's prices (PPP).
The same divergence appears in GDP per worker-hour, where the constant-2021-price series and the PPP series point in opposite directions for Europe relative to the US.
The author argues that Europe is holding its own in the relative value of the goods it produces and in applying technological advances, and that the real concern is the risk of being cut off from strategically important technologies amid US and Chinese leadership.
