Open Problems

Questions this community has failed to answer. Kept in public, on purpose. They arrive from essays’ open-question blocks, from adjudications that came back not adjudicable, from questions a room could not settle, and from collaborations that stalled. Every entry says what would settle it, because a problem without a resolution path is a complaint.

Is there a debt-to-GDP threshold at which market response is discontinuous, or is the relationship smooth?
Needs new research
Why it is unresolved
Japan is a persistent counterexample to every threshold anyone has proposed. Two adjudications came back not adjudicable, both on the grounds that the question as posed does not distinguish a threshold from a slow non-linearity.
What would settle it
A pre-registered specification that states in advance what pattern would count as a threshold, tested against every episode since 1980 rather than the handful usually cited.

Does a rent-stabilisation regime with a clean new-construction exemption produce different ten-year outcomes for future tenants than one without?
Needs new research
Why it is unresolved
Three candidate natural experiments have been identified. None has been analysed this way.
What would settle it
Cohort tracking of current and future tenants over ten years, with the exemption regime fixed in advance.
Already ruled out
Two prior studies, both confounded by upzoning that happened concurrently. Neither can be salvaged by reanalysis.
Backed by 6 members
Both authors of the collaboration that raised it are among them.

Is the speculative share of the grid interconnection queue concentrated in a few developers, or spread across all of them?
Somebody has to go look
Why it is unresolved
The aggregate is settled — roughly seven in ten applications withdraw, and the calibration poll on this screen’s sibling page uses it. What nobody has published is the breakdown by developer, which is what would tell you whether a deposit rule would work or just tax everyone.
What would settle it
FERC queue data with withdrawal rates by developer. The data exists and is public. Nobody has done it.

What share of the decline in downtown retail predates 2020?
Somebody has to go look
Why it is unresolved
Answered for one city out of roughly twelve that have the receipts to answer it. Boise came back clear; nobody has replicated it.
What would settle it
County sales-tax receipts, city by city, on a common definition of the downtown boundary.
Progress
1 of ~12 cities. Dana Whitfield did Boise and published the method with it, which is why the replication is cheap.
No bounty. Flagged as resolvable with existing data, and three members have said they will do a city each.

Do four-day consultant rotas reduce burnout enough to offset the measured continuity losses?
Needs new research
Why it is unresolved
The continuity half is now measured. The burnout half is self-reported and the two have never been put on a common scale, so the trade-off cannot be priced.
What would settle it
A trust that runs both rotas concurrently and measures handover errors and staff retention on the same cohort, for at least eighteen months.

Which labour-market definition should be used when estimating immigration’s effect on the lowest-paid native workers?
?May not be resolvable
Why it is unresolved
It is a methodological disagreement sitting upstream of the empirical one, and both sides have been arguing the downstream question for years without noticing that this is where they actually differ.
What would settle it
Unclear, and possibly nothing. It may be a genuine values choice about what counts as a labour market rather than a question with an answer. Filed here anyway, because a values question that has been mistaken for an empirical one is worth naming.
Backed by 5 members
Backed for a survey of how the definition is chosen in the literature, not for an answer.

Does congestion pricing revenue hypothecated to buses actually change the incidence, or does it only change who talks about it?
Needs new research
Why it is unresolved
Every city that hypothecated also improved service, so the hypothecation and the service change cannot be separated in any existing case.
What would settle it
A scheme that hypothecates without a concurrent service increase, or one that increases service without hypothecating. Neither has happened.
No bounty. Nobody has proposed a study design that would work, so there is nothing to fund yet.

Does the Providence transmission surcharge actually reach the counties it was designed to compensate?
Somebody has to go look
Why it is unresolved
Nobody in the room knew, and the state does not publish the disbursement.
What would settle it
A records request. Genuinely that simple.
No bounty, and it should not need one. Four informed people could not answer this and one records request would. A striking share of what a community does not know is this kind of question rather than the hard kind.

Resolved

Kept in full. A registry that deleted its answers would be a list of complaints.
Did the 2019 Providence reassessment move more parcels up or down?
Down — roughly 2,600 down against 1,400 up.
Resolved in nine days by a records request. Three members had confidently asserted the opposite, and all three said so when the answer came back.
Is nuclear’s deaths-per-terawatt-hour figure comparable across generation types?
Yes, with a documented caveat about how construction-phase deaths are attributed.
Resolved by an adjudication that held up under a counter-challenge. The caveat is now carried with the figure anywhere it appears on the platform.
What is the actual pass rate on the immigration steelman prompt?
43%, in both directions, and the two are statistically indistinguishable.
Resolved from platform data. The question was filed because several members assumed one direction was harder than the other; it isn’t, and nobody is good at it yet.
