Warsh’s Low/No Guidance Approach at Fed Makes Market Participants Nervous – – Which May Be a Good Thing

Under Jerome Powell, a typical FOMC meeting had become almost a market event in itself. Traders didn’t just care about the rate decision. They dissected every word of the statement, every sentence of the press conference, and especially the “dot plot,” looking for clues about where rates might be six months or a year from now. The Fed wasn’t simply setting monetary policy—it was guiding expectations. Markets often moved as much on hints about future decisions as on the decision itself.

The first two FOMC meetings under Kevin Warsh have felt very different. The dot plots are gone. Forward guidance has largely disappeared. Instead of trying to signal the likely path of policy, Warsh has repeatedly stressed that the Fed will respond to incoming data when it arrives, not commit itself to forecasts that could prove wrong. At his latest press conference, he described avoiding forward guidance as “prudent” given current uncertainty, while reminding reporters that “There is no soft or alternative inflation target—only 2%.”

This is a huge change in communication style, which is having real world consequences.

Warsh long argued that forward guidance can box policymakers into decisions based on yesterday’s forecasts instead of tomorrow’s realities. That is, once their tentative plans had been put out in public, there was a psychological bias among Fed members to lock in on those projections, which would inhibit their ability to rationally interact with the most recent data and situation. So now, rather than telling markets what the Fed expects to do, he wants investors to make decisions based on fundamental economic conditions, knowing that the central bank will react only after the facts justify it. At the latest FOMC meeting he said, “Market participants are learning to play the ball, not the referee—and market prices will continue to respond in the direction and magnitude they see fit. This is, in my view, a change for the better—and we are just getting started.”

That approach chips away at what investors have come to call the “Fed Put”—the belief, built up since the 2008 financial crisis, that the central bank will fairly quickly and forcefully step in to support markets whenever things get rough.

If that belief fades, financiers may think twice before taking excessive risks. Leverage becomes more dangerous if there is less confidence that easier monetary policy will quickly arrive to cushion losses. Risk premiums may better reflect actual economic uncertainty rather than expectations of future Fed support. That is the possible good side of Warsh’s more hands-off approach. Ideally, business people will exercise more prudence on their own, lessening the odds of financial catastrophes that would require Fed intervention.

On the other hand, markets hate uncertainty, and less guidance means more volatility around Fed meetings. I think Powell tried to use sheer talking (jaw-boning) as a tool to influence market rates, lessening the need for the Fed to actually employ its blunt instruments there. Warsh seems to have taken that tool off the table.

Also, I think some (not all) the causation for the rise in 30-year Treasury bonds to twenty-year highs, and of home mortgage rates to one-year highs accrues to Warsh. First, by eliminating dot plots and forward guidance, he has increased uncertainty about the future path of policy. Investors can no longer confidently assume the Fed will ease at the first sign of economic weakness. That uncertainty can raise the term premium, pushing long-term yields higher.

Second, if markets believe the “Fed Put” is weaker, they may demand higher yields to hold long-term bonds because they perceive less protection from adverse economic or financial shocks. In other words, investors require more compensation for risk.

Whether today’s higher long-term rates are a healthy reflection of economic realities, or an unhealth drag on growth, is a matter of debate.

AI Innate Preferences Paper on Arxiv

Please check out my new paper, with Joshua Foster

The Innate Economic Preferences of Language Models (arXiv link)

Abstract: Language models increasingly settle real resource tradeoffs on behalf of principals yet their economic preferences remain unobserved. We demonstrate their generation rule is isomorphic to the random utility model of discrete choice. This allows internal logit scores to structurally identify preferences. Estimating risk attitudes across twelve models in a portfolio task reveals universal but heterogeneous risk aversion. Although models reject strictly dominated options, their elicited preferences fail invariance tests and violate the independence of irrelevant alternatives across varying experimental prompts. Finally, fine tuning establishes that a principal can explicitly engineer a target risk attitude.

I hope you will refer to the manuscript for details, but I will share one picture here. This is panel (a) of Figure 3: Empirical indifference curves for open-weight models mapped over the portfolio space.

In simple language, what the red/blue picture shows is that the Qwen language model is picking the portfolios that offer more money (in expectation, with a distaste for excessive risk). That’s basically what a rational actor should do. We find that the language models make fairly consistent choices and rarely violate the monotonicity requirement for a well-behaved utility function.

How we describe this figure in the paper: “Starting from a base bundle with expected return µ = 10 and risk σ = 30, we sweep over the dense grid of alternative portfolios from our experimental protocol and record the position-corrected logit gap between each grid portfolio and the base. The yellow dashed line overlays the indifference curve implied by the mean-variance structural estimates, and the heatmap colors encode the sign and magnitude of the logit difference, with blue regions preferred to the base and red regions dispreferred. Several patterns emerge from these plots. All six models produce upward-sloping indifference curves, confirming that higher risk must be compensated by higher expected return.”

We think this basic research on behavior is important, for alignment research and for business applications with delegating work to AI agents. The first question to ask, before testing whether we can impose our preferences on AI agents, is whether those agents have preferences at all in a consistent sense.

GDP Growth in the Second Quarter: Updated Forecasts

GDP growth data for the second quarter of 2026 comes out tomorrow. As I have been doing for the past several quarters, here is an update on two model forecasts (Atlanta and NY Feds), betting market implied estimates (Kalshi), and an average from a survey of economists (WSJ). Yellow shading indicates which forecast was closest to correct in each quarter (green is if two forecasts were about the same).

In the past two quarters, the WSJ survey has been the best predictor. The Atlanta Fed GDPNow model used to be my favorite, but it has performed pretty poorly in the past 3 quarters. As I have discussed before, an average of the Atlanta Fed and Kalshi was better than any single predictor. I continue to include the NY Fed estimate, even though it seems to be a very terrible predictor, because some people like to talk about it.

The Atlanta Fed, Kalshi, and the WSJ survey are all showing very similar estimates for Q2. If I was a betting man, I would bet on 1.8% for the BEA advance estimate.

Top EWED Posts of 2026

These are notable posts from 2026, roughly presented in descending order, starting with the post that got the most views.

  1. The US Has One of the Highest Fertility Rates Among Peer Countries

By Jeremy Horpedahl (https://x.com/jmhorp)

“Does the US face a falling birth rate? Yes. Is this as dramatic as most other countries? No.”

Another good follow for issues of the family is Melissa Kearney (https://x.com/kearney_melissa)

2. Claude Mythos Is Such a Dangerous Hacker Engine That Anthropic Has Withheld Broad Release

Scott Buchanan released a timely post in April.

3. What is an AI Skill?

Zachary Bartsch: “A skill can be just plain text written conversationally, it can be a list of rules, mathematical expressions, or even the foundational code that you want your AI to readily modify and apply. Essentially, saying ‘skill’ is the same as saying ‘pre-prompting’ with various degrees of specificity. Rather than writing a prompt each time, you can recycle a set of prompts that you’ve stored in a file. That’s all that a skill is.”

Plus, Zachary provided some useful history of “Explainer text files”

4. Although published in a prior year, this post from Zachary has also done well in 2026: The Mythology of Rice and Beans

“Not a single one of these foods is an ‘incomplete protein’. Yes, the mass that you’d need to eat differs, but there is not much that is exciting about legumes and grains as a combination.”

Anyone who has gone grocery shopping in 2026 knows this is the year of protein.

5. Scott Buchanan considered the price trajectory of silver: Is the Silver Bubble Bursting?

Out of curiosity, I checked the price. Within a week of this post, the price of silver had actually gone up. But after a final peak in late January, the price has declined. As of today, it is down from any of the prices posted in January of 2026.

6. Another bubble post from Scott: Chipmaker Stock Prices Explode: The Latest Bubble?

In addition to financial speculation, these chip prices also affect consumers trying to buy a high-performance laptop.

7. Scott on AI news: Oops: Anthropic Accidently Leaked the Entire Code for Its “Claude Code” Program

“Gleeful researchers, competitors, and hackers promptly downloaded zillions of copies. Anthropic issued broad copyright takedown requests, but the damage was done.”

8. James Bailey considered: Is a US Oil Export Ban Coming? in light of the conflict with Iran

9. Mike Makowsky wrote this haunting poem “Oh, what shall all the candlemakers do now that the sun has risen?”

The actual AI problem in academic economics

He talks about the referee process, since that is where the main decisions happen, as much as the “writing process.” No one has all the answers, but Mike is doing us all a favor by getting some of this real talk out in the open. Please comment if you have more ideas on where to go from here.

I’ve seen chatter about this topic on Twitter/X, but I’d love to see some more blog posts from tenured folk because it helps with the hidden curriculum problem.

10. Even though it was posted in 2025, this post by Jeremy got more attention: Spending on Necessities Has Declined Dramatically in the United States

“Would you have guessed that in the “good old days” of the 1950s and 1960s, the average US family was spending 30-40% of their income on food and clothing, something that today we spend barely over 10% on? To understand the challenges we face today, it’s important to have the context of how bad the past was.”

Jeremy has been telling this story for years. Interestingly, world cup tourist discourse seemed to push a few more people over the fence (why hadn’t they just read our blog?). Most Americans are rich.

11. Humanity’s Last Exam in Nature by James.

“We start asking it questions we don’t know the answer to.” is reminiscent of my recent post Fable on Legibility

12. Scott: SaaSmageddon: Will AI Eat the Software Business?

Since the ChatGPT launch, I have heard conflicting stories on the impact of AI on white collar jobs such as software engineering. There have been layoffs and, for example, ex-Meta employees who struggle rematch in at their old salary. I have also heard claims that the demand for software engineers is actually increasing, perhaps because AI makes them more productive.

15. Jeremy is still right, as the foreign tourists saw this summer: Average Wealth for Younger Generations Continues To Exceed Past Generations

16. Joy Buchanan: arXiv will ban authors who submit papers with LLM mistakes

The problem echos Makowsky’s post, which ultimately rests on readers and the referee process. I like to say “readers are that which is scarce,” meaning that it’s not difficult to produce writing.

17. Sometimes I just like to highlight a Jeremy post that made me laugh, even if it did not get top views: Berries Are Probably Not Making Parents Go Broke (Probably)

We’ve been cited in most of the major news outlets at this point, but this year was a first with: EWED cited in Top Demography Journal

Blogs are not niche anymore. More people than ever, including many researchers at top schools, have decided to start a Substack. Of course, peer-reviewed and prestige-published research still has a primary place in the discourse. Many of the blog posts are ABOUT the primary objects of research.

I saw something called InTheWeights in 2026 that made me think folks at research schools might be strategic in starting to blog now. ChatGPT reads our blog. One reason I think that to be true is that some of our reader traffic comes from ChatGPT.com and Claude. I think our work is getting repackaged as LLM answers to millions of people, some small percentage of those answers provide attribution to us, and then a small sliver of those answers results in users clicking over to us as the primary source for an answer.

It will be a long time before tenure decisions are based on where you are In the Weights. But our crew would do well on that metric. Our work is legible to AI because we have been blogging ungated here for years.

How to Escape the Productivity Slump

I have a new essay up at Human Progress today. Here’s a slice of it:

The productivity slowdown is not an immutable law of nature. It is, at least in part, the consequence of policy choices. Human ingenuity remains as powerful as ever. We have more scientists, more capital, and better tools than any previous generation. The challenge is not generating ideas; it is allowing those ideas to spread.



An additional one or two percentage points of annual productivity growth may sound insignificant. Yet when compounded over decades, the effects are transformative. Higher productivity means higher incomes, better health outcomes, more abundant energy, and greater opportunities for future generations. The ideas already exist. The question is whether we will allow them to flourish.

Read the full piece.

Uncertainty Increases Profits?

Most people have an intuition that uncertainty can harm economic outcomes. Baker, Bloom, & Davis (2016) and Bloom (2009) demonstrated that industrial production and manufacturing decline in the face of policy uncertainty. The typical mechanism that people suggest is that uncertainty about the future causes people to engage in precautionary saving, resulting in fewer sales.

The theory continues that firms consequently decrease production as demand for their output declines. Firms aren’t interested in causing the quantities supplied and demanded to be equal. Rather, they don’t want to produce too many goods that don’t get sold or don’t get sold at an adequate markup. Production is costly.  A related theory is that more persistent or longer-run uncertainty can also depress investment, since the riskier future increases the tail risk of losses.

Rather than make a risky investment, one could instead just hold off and wait for some of that uncertainty to get resolved. There’s tradeoffs to this, of course. As future costs and benefits become clearer, they also get priced-in to asset values. So, there is an optimization problem. The possible downside outcome is big and uncertain. If the risk of the investment gets resolved and the downside outcome is still too likely or harmful, then a project manager did the ex-post ‘right thing’ by waiting.

But, if the downside risk disappears or is found to be very small, then waiting to invest in the project incurs an economic cost. Either 1) the profitable project and its associated profits will occur later and less valuably, or 2) other firms also resolve their uncertainty and bid up the price of the project’s inputs. Invest too early, and the downside is large and uncertain. Invest too late, and you may lose the potential upside partially or entirely.

But can uncertainty systematically increase profits?

Walter Oi said yes.

The Journal of Healthcare Finance Is Back

Most academic journals are run by big for-profit publishing companies, and most of the rest are run by universities or big academic societies. The Journal of Healthcare Finance was an extreme outlier from this norm, run single-handedly by Editor-In-Chief James Unland since 1994. It was the rare journal that was free both for readers and authors.

I loved the idea of having a single person truly in charge and accountable without being slowed by a complex bureaucracy. But eventually a single person will want to, or have to, move on. Having an institution run a journal can ease this process, though an individual can still try to find their own successor.

In this case, The Journal of Healthcare Finance had been on hiatus since its Editor-In-Chief stepped back, with its last issue published in 2023. Their old website domain had expired- not a great look for anyone who published there and was going up for a job or tenure.

But now it is officially back at a new domain, with the single Editor-In-Chief replaced by a full editorial team, and accepting submissions again with the hope of releasing a new issue this year.

Selfishly, I’m happy to see this both because it means they will continue hosting my past publication, and to have a potential outlet for my future work. I recommend that other health economists and health services researchers give it a try, though as of now I have no personal experience with the new editorial team.

By the Numbers: Florida’s Property Tax Amendment (2026)

Voters this November will face a proposed amendment to the Florida state constitution on property tax reform. Currently, Florida has what’s called a ‘homestead’ exemption of $50,000. If a residential property is your primary residence, then your home’s assessed value is $50k less before taxes are calculated. There is no exemption for rental property or 2nd homes or vacation homes. The proposed amendment increases the exemption to $250k by 2028 and then indexes it to inflation.

First, let’s get an idea of the magnitudes. The median home in Florida is priced at about $400k and the average property tax rate is around 0.8%. Below compares the current consolidated tax bill against that of the proposed amendment. Given current home prices and local tax rates, the new exemption would have a huge impact on municipal governments who get the bulk of their revenue from property tax. In fact, there is no Florida state property tax, so the proposed amendment would adopt a new rule for municipalities and not the state government.

What Motivates the Amendment?

The current homestead exemption of $50k was established in 2008. A subsequent amendment in 2024 allowed half of that to be indexed to CPI-U. The average home price in Florida has risen 114% since 2008 and 84% since 2020. That’s a lot faster than inflation, but the tax burden is partially offset by a maximum of 3% annual increase in assessed value. Regardless, many individuals face a larger tax bill over time even independent of whether their income or use of public services has changed. Plenty people are feeling the squeeze.

What’s the Purpose of the Homestead Exemption?

The exemption is available for primary residences only. That means that rentals and vacation homes do not qualify. It’s important to keep in mind that, given some total revenue, every tax break for one group or activity implies a higher tax rate for others. So, clearly, the effect is to tax residents less and tax seasonal residents and visitors more. Florida doesn’t have an income tax, but it does have a sales tax, gasoline tax, and others that are disproportionately borne by non-residents. Given that higher income individuals tend to have higher home values, the homestead exemption is a way to lower the tax burden of lower income households. Obviously, the lowest income individuals are renters, but so are non-residents who Florida prefers to tax.

The Economics

Homeowners

The exemption is enjoyed by all primary residences, but helps low income owners the most. And, given a stable amount of municipal tax revenue, a higher homestead exemption requires that municipalities replace that revenue. This might take the form of higher local fees and taxes, making life harder for lower income people to, say, own a car or make purchase if taxes on those activities rise. Revenue stability might also be helped by higher property tax rates. The higher the property value is above $250k, the greater the average tax burden that is borne. So, someone with a very high property value may find themselves with an even higher property tax bill after municipalities adjust to the proposed statewide rule. In this sense, the new amendment would be a step in the direction of tax progressivity (a higher proportion taxed from those with higher income/wealth).

Indexing

Normally, I am in favor of indexing nominal values to CPI. In this case, we need to think about what the goal is. Let’s assume that the goals is to provide relief to lower income homeowners specifically and all primary residence homeowners generally. Does indexing to the CPI help? It depends!

Do NBA Teams Play Worse In Back-To-Back Games?

The conventional wisdom is that the NBA regular season has too many games. Teams play worse because they are tired, or injured, or resting their stars so they can be ready to actually play hard in the playoffs.

New research shows that the conventional wisdom is…. probably right. In particular, teams play worse by many measures when they have to play two days in a row. That’s what Max Aicardi and I found in a paper published today, “Running on Empty: How Back-to-Backs Impact Pace and the Four Factors of Basketball Success“:

Teams on the second night of a back-to-back shoot less efficiently (lower eFG%), grab fewer offensive rebounds, and play at a slower pace. On defense, they allow opponents to shoot more efficiently, force fewer turnovers, and give up more free throw attempts and second-chance opportunities. Turnover percentage and offensive free throw rate did not change significantly, consistent with our conceptual framework’s distinction between effort-dependent and execution-dependent metrics. While not every metric changed significantly, the overall pattern is clear: second-night back-to-back scheduling is associated with a measurable decline in team performance

The effect sizes here tend to be small, around 0.5-2%, but they are statistically significant given that we studied over 20,000 games, and practically significant given how close NBA games are.

Max had the idea for this paper and wrote the first draft as a student in my Economics Senior Capstone class in 2025. After he graduated, I joined the paper as a coauthor to get it ready for journals. We share the data and code for the paper here.
