Fantastic opportunity to work with the very best of fiscal policy analysts.
🚨Rare and exciting opportunity 🚨

We're looking to hire an exceptional economist to work on fiscal policy at the IFS. We don't do this often. It's a chance to shape, carry out and communicate research on some of the highest-profile topics in UK economic policy. [1/4]

This feels like an important finding (albeit from one US study):

GLP-1 medications (Ozempic, Mounjaro etc) *do not* pay for themselves by reducing other types of medical spending, at least in the first five years. If anything, GLP-1s increase other forms of medical spending.

A great thread summarising some fascinating work on London's ULEZ. As you might expect, its introduction led more people to switch to electric cars and public transport, but ULEZ also affected house prices and business locations. Low-income drivers were more likely to just pay the charge.
NEW: How did the introduction of the Ultra-Low Emissions Zone (ULEZ) change London’s geography of work?

In a new @theifs.bsky.social paper, @joelkariel.bsky.social, Fizza Jabbar and I have taken a look – and it turns out people adapt in surprising ways. A thread.

A short seven years (!) after I started writing the code, it’s great to see this paper published.

We use high-frequency NHS to data show that short-staffed, less experienced nursing teams deliver worse outcomes – with the largest mortality impacts for patients with sepsis.

An interesting nugget buried in Treasury evidence to the Pay Review Bodies:

In recent years, the NHS and other departments have (with HMT permission) raided capital budgets to fund unexpectedly high pay awards. Updated guidance explicitly rules this out.

This is a careful, valuable piece of research demonstrating that cuts to non-disability benefits in the 2010s led to more people claiming disability benefits. Notable, though, that extra spending on disability support only undid a very small % of the original savings.
These effects reduce the fiscal saving from cuts to benefit amounts, but only modestly. Increased disability benefits only reduced savings by 1%-4% for the three cuts to benefit amounts we study.

We're looking for an outstanding economist to lead our health team.

This is a rare opportunity, with a great team. If you want to lead economic research with real-world policy impact, there really is nowhere better than the IFS.

Hospitals currently have a lot more people admitted with flu than at the same time in recent years. It remains to be seen how the peak will compare to previous years. (Half the IFS healthcare team are also currently laid low with it...)

NHS hospitals in England are getting more productive, according to official data. But the waiting list for pre-planned treatment is barely falling.

Why? It turns out, the NHS is now doing more stuff to the average patient before they leave the waiting list. See @maxwarner.bsky.social's thread 👇
NEW: Hospital productivity growth is beating the government’s targets. So why hasn't the NHS made more progress on cutting elective waiting times?

In a new @theifs.bsky.social comment, we examine what’s driving the divergence between two of the government’s biggest NHS priorities.

NEW: Strong productivity growth and increasing funding has meant English hospitals have been delivering much more elective (pre-planned) care.

So why isn't the waiting list going down more quickly?

🧵 @maxwarner.bsky.social and Olly Harvey-Rich examine what's going on:

At no point in the process did the OBR have the government missing its fiscal rules by a large margin. Leaves me baffled by the months of speculation and briefing. Was the plan to lead everyone to expect a big income tax rise, then surprise them on the day by not doing it..?
November 28, 2025 at 11:27 AM
Further to this, in a (plausible) scenario presented by the OBR, official plans imply that "unprotected" departments would face cuts of >3% per year, equivalent to more than £20 billion, between 2029 and 2031. That includes police, courts, job centres, colleges, prisons, HMRC, border force... 🤔

Underrated part of yesterday's Budget was what's happening to public service spending in 2028-29. Spending Review settlements reopened just 5 months after the SR to account for loosely-specified 'efficiency savings' of £1.4bn in 28-29 (rising to 4bn in 29-30)
November 27, 2025 at 11:58 AM
Having now mulled overnight, a few aspects of the Budget where the government deserves some credit:

1) Increasing fiscal headroom
2) A plan for how to tax electric cars, at last (even if imperfect)
3) A plan to gradually undo the "temporary" 5p cut in fuel duty
Some immediate Budget takes from @helenmiller.bsky.social and the IFS hive mind at the link below.

What's most striking, to me at least, is the decision to rely so much on tax rises that kick in at the back end of the parliament - just in time for the next election...

The OBR will now only assess performance against the fiscal rules once per year (in the autumn) but will continue to produce two forecasts each year. Relies on the world understanding that if the OBR forecast a current budget deficit in the spring, it's not technically a breach.
November 26, 2025 at 1:41 PM
There's an interesting political economy angle to the fact that, with basically every single tax parameter frozen in cash terms (and personal tax thresholds now frozen to 2031), inflation is extremely beneficial for the public finances.
Rachel Reeves can count herself (at least a bit) lucky. OBR productivity downgrade would have knocked £16 billion off tax receipts. But she was saved by £32 billion of *extra* receipts from higher inflation and a shift to more tax-rich growth (lower profits, higher wages).

With apologies to the poor person at the OBR who accidentally hit upload...

Key public finance story: smaller OBR downgrade than expected, more borrowing in the short term (extra spending, mostly unanticipated), less borrowing in the medium term (as tax rises kick in).

Amidst ceaseless discussion of possible tax rises, it's worth remembering that spending cuts could be part of any Budget consolidation package. One challenge is that detailed department-level spending plans up to 2028–29 were agreed only in June...

We've looked at the options 👇

This is the point. Policy *should not* be adjusted or fine-tuned in response to minor forecasting judgements. Decisions about whether or not to break a prominent manifesto promise *should not* depend on minor forecasting judgements. This stuff matters. We've got to do better than this.
I know it’s always like this. But one striking thing from the budget kite flying and kite pulling back in, is how major policy decisions are constantly being buffeted around by iterative forecast changes.
All feels a bit of a silly way to be making major economic policy & political decisions.
