Essay Four｜Why Can System Contributions Not Be Fully Reflected in Price?
I. What is price best able to express?
Price is best at expressing exchange at a boundary.
How much a product sells for, how much a service is paid, how much risk a contract carries, and how much return a loan requires can all be recorded and settled at an interface.
These forms of value have clear boundaries:
- Who provides?
- Who buys?
- When does the exchange occur?
- Who bears responsibility?
- How are gains divided?
Interface value is therefore easy to see.
It enters company accounts, contracts, tax records, profit, share prices, and statistics.
But some of the most important contributions inside a production system do not occur at clear boundaries.
They enter all subsequent production.
II. Why is system value difficult to disaggregate?
The value of a road is not only the toll it collects.
It also enters:
- business location;
- labor mobility;
- logistics time;
- land use;
- regional markets;
- access to education and health care;
- countless later investments.
The value of a reservoir is not only its electricity revenue.
It may also enter:
- irrigation;
- flood control;
- urban water supply;
- industrial water use;
- population support;
- land value;
- regional stability.
A power grid, a basic school, a public-health system, and a program of foundational research have similar characteristics.
They do not merely create one transaction.
They change the conditions under which every later transaction can occur.
Therefore:
Interface value is easier to settle because it occurs at a boundary. System value is harder to disaggregate because it has entered all subsequent production.
III. Inability to measure precisely does not imply nonexistence
Many contributions of a production system are difficult to isolate precisely.
But difficulty of separation does not mean absence of value.
Human beings understood that food sustains life before they developed nutrition science, caloric measurement, and models of metabolism.
Likewise, Productive-Forces Economics must first identify:
- which capacities are preconditions for the system to continue;
- which contributions repeatedly support later production even without immediate monetization;
- which capacities cost far more to rebuild after disappearance than to maintain in ordinary times.
Measurement comes later.
Existence comes first.
The fact that value cannot yet be precisely disaggregated does not make system contribution nonexistent.
IV. Why are system contribution and monetary return often asymmetric?
System contribution has several characteristics:
- beneficiaries are dispersed;
- time horizons are long;
- value enters other actors;
- importance may appear only in crisis;
- successful maintenance makes the contribution less visible;
- not every beneficiary can be charged individually.
An activity can therefore be vital to the system while remaining unable to earn sufficient monetary return.
Conversely, an interface may earn a high return without creating an equal amount of system contribution.
This does not make interface profit illegitimate.
It means only that:
Monetary return measures value that can be settled at an interface. It does not measure every contribution made within the whole system.
V. Why does Productive-Forces Economics need another perspective on value?
Conventional economics can continue to study:
- price;
- profit;
- cost;
- risk;
- rate of return;
- resource allocation.
Productive-Forces Economics must also ask:
- How much later production does a capacity support?
- Does it reduce the probability of system interruption?
- Can it help recovery after failure?
- Does it expand the capacity to absorb populations and regions?
- Does it preserve future productive possibilities?
This does not abolish price.
It recognizes that price sees only part of value.
Therefore:
Price answers, “What is this transaction worth?” Productive-Forces Economics also asks, “Without this capacity, can later production occur at all?”
Conclusion
The most important capacities of a production system often do not directly generate one settleable stream of income.
Their more common role is to allow other income, employment, technology, and life to continue existing.
Therefore:
System contribution is not a mysterious value outside price. It is the prior condition that allows price to continue to occur.
