WHITE PAPER
Given time is a real value that nobody counts. This document explains why, and proposes to record it without turning it into money.

01 — The starting point
Sitting with a parent, listening to a neighbour, passing on a skill: none of it appears in a nation's accounts. We measure what is easy to count, not what makes a life worth living.
Simon Kuznets, who built modern national accounting, warned as early as 1934 that « the welfare of a nation can scarcely be inferred from a measurement of national income ». Forty years later, Nordhaus and Tobin proposed folding household work and leisure into the accounts. The warning is as old as the instrument. — Kuznets, National Income 1929-1932, US Senate, doc. no. 124, 1934; Nordhaus & Tobin, Is Growth Obsolete?, NBER, 1972.
One sentence that stayed
« Gross national product measures everything, in short, except that which makes life worthwhile. »
Robert F. Kennedy — University of Kansas, 18 March 1968
According to the International Labour Organization, unpaid care work amounts to about 9 % of world GDP — close to 11 trillion dollars — and 10 to 39 % of GDP depending on the country. Women perform 76.2 % of it. Marilyn Waring showed it in 1988: what the accounts leave out, society stops seeing. — ILO, Care work and care jobs, 2018; M. Waring, If Women Counted, 1988.
The question of this document is simple: what if we learned to record what counts?
02 — The inheritance
In the 1980s, Edgar Cahn invented time banking: an hour is an hour, whatever the task and whoever gives it. An idea of equal dignity — almost everyone has something their community needs. — E. Cahn & J. Rowe, Time Dollars, 1992.
The reported effects are real — wellbeing, a sense of usefulness, social ties. In fairness: this evidence base remains fragile, largely qualitative, with few objective measures and little follow-up over time. — G. Seyfang, research on time currencies and the core economy; systematic reviews, 2018-2025.
Time banks keep a unit that betrays them. You give an hour, you hold a claim on an hour: that is credit — a complementary currency in disguise. Its limits are documented:
| Limit | What it produces |
|---|---|
| Hyper-locality | Small circles → few services → hard to grow. |
| Double coincidence | Supply must meet exactly the right need, at the right moment. |
| Brokerage dependence | Administrative cost, a dedicated broker, funding. |
| Distortion | Time credit recreates market effects that a gift does not. |
The turning point
Keep the intuition — time as value, the equal dignity of the hour — and break the unit. Given time is not a claim to spend, but an energy to record.
03 — The heart of the concept
Treating given time as an energy is not a metaphor: it is the choice that allows it to be recorded without creating debt. Everything rests on the nature of what is written.
Facing the future: « I am owed ». A balance to spend. Value is what I keep. The logic of the hour-credit, and of money.
Facing the past: « this happened, and it mattered ». A testimony. Value is what I gave. A memory, not a wallet.
The distinction is not new. Marcel Mauss showed in 1925 that a gift binds a relationship, not a numbered debt; Richard Titmuss, comparing donated and purchased blood, established that payment can destroy the generosity it claims to encourage. Recording without crediting takes that warning seriously. — M. Mauss, The Gift, 1925; R. Titmuss, The Gift Relationship, 1970.
Making care visible, lasting and transmissible — without ever turning it into a balance.
04 — Two gestures
The sun says how the energy is given; the moon, how it is read. Neither accumulates — which is why this is not a currency.
The sun keeps no ledger of debts: it radiates. A gift does not engrave a claim, it engraves a bond and a place. Being able to give is the reward.
You do not read a balance; you read phases. Giving waxes, wanes, returns. The number stays a tool of the gesture, never a mirror of the person.
The honest objection — what about free riders?
« If giving grants no right, what stops someone from taking? » Three answers. (1) The record inscribes reality: whoever never gives is visible, nothing is hidden. (2) There is no balance to loot — you cannot steal a claim that does not exist. (3) Standing is earned by giving; giving nothing accumulates nothing. Elinor Ostrom's work on the commons shows what actually holds a commons together: the visibility of contributions and rules made by those who live under them — not punishment. — E. Ostrom, Governing the Commons, 1990 (Nobel Prize in Economics, 2009).
05 — The horizon
If given time is recorded, a society can be read by what it cares for — not by what it produces. Two territories with the same GDP can be opposite worlds.
Poor and bound
Little monetary output, a dense fabric of care. GDP calls it poor; life holds.
Flourishing
Prosperity and bonds. Material wealth that has not sacrificed care.
Fragile
Neither resources nor a human safety net. The absolute priority for support.
Rich and alone
GDP applauds; isolation grows. Prosperity that protects from nothing.
This axis is not decorative. A meta-analysis covering more than 300,000 people established that the quality of social ties weighs on mortality as much as recognised risk factors. What GDP ignores, bodies record. — Holt-Lunstad, Smith & Layton, Social Relationships and Mortality Risk, PLoS Medicine, 2010; R. Putnam, Bowling Alone, 2000.
Read, do not rank
Every « beyond GDP » index — HDI, the Stiglitz-Sen-Fitoussi commission, the Better Life Index, the Doughnut — shares one temptation: producing another number to maximise. A « GDP of care » would rebuild the trap. We count to remember; we give to read to understand.
06 — The empty place
Learning to record what counts: taking the time given to others and granting it a lasting existence, without corrupting it into money.
Time banks had seen the value of time, but locked it inside a claim. GDP gave the world an accounting, but blind to what holds it up. Between the two lies an empty place: an accounting of what actually counts, which is neither a credit nor a score.
« Given time does not disappear. We are learning, at last, to keep its trace. »

Note on method
No adoption projection appears in this document: those are assumptions, not forecasts, and they do not belong in a text about a concept. One unconfirmed attribution present in version 2 (a prediction ascribed to « F. Fisher ») has been removed. The limits of time banking are stated from the reviews that document them, including where they weaken our own thesis.
