Re:Why can capital accumulate but lifetime cannot? (SSRN) on Sunday March 08, 2026 @08:24PM (#47303236)
HN note: the SSRN page is still being processed and temporarily shows the standard “under review” placeholder.

The working preprint version is available here:

https://doi.org/10.5281/zenodo.18912296

The paper explores a structural asymmetry in macroeconomic accounting:

Capital accumulates and appears as a stock variable.

Human lifetime accumulates historically as well, yet it never qualifies as a macroeconomic stock and only enters models as a flow or demographic constraint.

The argument is that stock variables require two institutional properties: (1) detachment from biological identity (2) continuity across generations.

Capital satisfies both. Lifetime does not.

Curious how economists or system designers here think about this constraint.

Re:Why can capital accumulate but lifetime cannot? (SSRN) on Sunday March 08, 2026 @08:08PM (#47303125)
Macroeconomics treats capital as a cumulative stock.

Capital persists through time, can be inherited, and therefore appears in macroeconomic accounting as a stock variable.

But there is a curious asymmetry.

Human lifetime also accumulates historically: humanity continuously adds lived time across generations. Yet cumulative lifetime never appears as a macroeconomic stock.

Instead it only enters macro models as a flow (labor supply) or as a demographic constraint.

One possible explanation is institutional rather than physical.

For a variable to qualify as a macroeconomic stock it must satisfy two conditions:

1. Detachment from biological identity 2. Institutional continuity across generations

Capital satisfies both conditions. Lifetime does not.

If this reasoning is correct, macroeconomic accounting may structurally privilege capital accumulation.

Curious how economists or system designers here think about this asymmetry.

I’m exploring whether a non-monetary economic protocol can be validated purely as a deterministic state machine.

No token launch. No deployment. No market simulation.

Just:

– explicit state surface – deterministic events – invariant layers (correctness + safety) – stress scenarios (S01–S22)

The goal is structural falsifiability.

If the invariant system collapses under adversarial sequencing, I want to know.

Ask HN: How would you formalize a time-based macroeconomic model?

I’m exploring a macroeconomic model where time is treated as a primary unit of value rather than a secondary pricing variable.At a high level, the idea is to index value issuance and economic contribution directly to time, with fixed temporal constraints, rather than to output, price, or currency supply.For those who have worked on economic modeling, mechanism design, or simulation...

That’s a fair point. I agree the current profitability is largely driven by demand patterns and regulatory arbitrage rather than pure market design. My comment was more about why the underlying event-contract model struggles to scale sustainably, even when interest exists.

One structural difference seems to be incentive alignment. Sportsbooks monetize volume and friction, while prediction markets depend on sustained liquidity and accurate pricing, which is much harder to maintain at scale. It feels less like a failure of the idea and more a mismatch between economic incentives and market expectations.
