Meetings as an Unpriced Externality

Meetings as an Unpriced Externality

What we actually think: "meetings are an unpriced externality" is a framing, not a term of art — it appears in practitioner discourse (most concretely around Shopify's meeting cost calculator), not peer-reviewed literature — but the structure it names is real and each piece is separately documented. The volume side is the best-measured: Microsoft telemetry shows the average Teams user's weekly meeting time up 252% and meeting count up 153% between February 2020 and February 2022, with after-hours and weekend work up 28% and 14% (primary-checked), and by 2025 the same telemetry shows 57% of meetings are ad hoc and post-8-p.m. meetings up 16% year over year. Executives average nearly 23 hours a week in meetings (primary-checked at HBR). We hold the volume claim at "moderate" only because it is single-vendor telemetry.

The externality mechanics are theory applied to calendars, and we grade them accordingly. The caller convenes at a private cost near zero; attendees bear the cost; the Otter/Rogelberg survey's decline gap (employees want to decline 31% of meetings but decline 14%, following organizational norms) is the cleanest behavioral signature of the missing price signal. The true cost also exceeds the booked slot: interrupted work gets done faster but at the price of higher workload, stress, and frustration (Mark et al. 2008, primary-checked from the author PDF), meeting load tracks daily fatigue, and harm is moderated by task interdependence and meeting quality — the same hour costs a maker more than a manager, which is Graham's maker's-schedule convexity point in psychometric form. One verification finding matters editorially: the famous "23 minutes 15 seconds to resume" figure does NOT appear in the CHI'08 paper it is usually attributed to; we encode it only as report-derived context and the essay should not lean on it.

On remedies, the evidence has a clear gradient. Field interventions that fence the commons (Perlow's quiet time, BCG's predictable time off) improved productivity and communication — held at "suggestive" purely because the primary texts are paywalled. Mass purges and meeting-free-day programs (Shopify's 322,000 deleted hours; Laker et al.'s 76-company percentages) are "anecdotal" no matter how famous: self-report, no control groups, survivorship in what leadership publicizes. The transport template is solid — Stockholm's congestion charge cut cordon traffic ~22%, more than forecast (primary-checked from the paper) — but the leap to calendars is analogy. There is no experiment anywhere that literally charges meeting callers and measures output. That is the thesis's unwelded link, and honest advocacy must present literal calendar pricing as the experiment someone should run, not as an established fix.

The counter-evidence disciplines the remedy rather than rescuing the status quo. Synchrony produces unpriced value symmetric to the unpriced cost: videoconferencing inhibits creative idea generation versus in-person (Brucks & Levav, primary-checked), firm-wide remote work made 61,182 Microsoft employees' networks more static and siloed (Yang et al., primary-checked), and proximity raises the coding feedback junior engineers receive by 18.3% in the revised NBER abstract (the seed report cites 23.9% from an earlier version — a discrepancy we flag). The optimum is interior: Laker's own data reverse at total elimination (primary-checked from the accepted manuscript), and Bloom, Han & Liang's RCT shows structured coordination days preserve performance while cutting attrition by a third. Correct pricing sometimes returns "this meeting is worth it" — and for some in-person convenings, the right price may be a subsidy.

Limitations of this ingestion: the seed report's quantitative model (the caller/planner wedge, fragmentation convexity, Pigouvian price p*, the V_sync(D) decision rule) is a managerial synthesis the report itself marks as theoretical — we did not encode it as claims, and any essay figure built on it must be labeled as theory parameterized by measured quantities. The report's citations were live URLs (unlike earlier citeturn-token reports), which allowed 16 of 24 sources to carry primary-checked excerpts; the remaining report-derived excerpts (Perlow 1999/2009, Luong 2005, Mroz 2018, Cross 2016's distributional figure, Malone & Crowston, Ostrom) are paywall-limited, not judgment calls. Per multi-agent coordination rules, this ingestion did not touch kb/kb.deps.json; the seed report is recorded in seedResearch above.

Pricing a congested commons reduces overuse in transport: Stockholm's 2006 congestion-charging trial cut cordon traffic to a stable level around 22% below baseline — beating the 10-15% political design target, landing almost exactly where the traffic-model forecasts (20-25%) said it would — with congestion effects larger than anticipated and favourable economic and environmental effects.
