Part I - Calculation and discovery
ECO.1 - Recover the Basis for an Economic Calculation
Type: Method pattern Status: Stable
ECO.1:1 - Problem frame
Use this pattern when a calculation ranks production or service plans but you cannot tell whether its prices and other weights represent exchanges and resource uses available to the people who must act. Start with the quantity that could reverse the choice and ask what transaction, displaced use or stated valuation gives it meaning. The result is a comparison with usable economic grounds, or a conditional choice with the missing ground exposed.
An adequate current quotation and resource account can be used as supplied. There is no need to reconstruct the whole economy before choosing a machine, a supplier or a service.
ECO.1:2 - Problem
An optimizer can solve the problem it receives while its numbers conceal the decisive difficulty. An internal transfer price may express a management policy; an old purchase price records a past exchange; a shadow price expresses a marginal trade-off within a particular optimization problem. Substituting one for another can rank alternatives which nobody can actually obtain.
Economic calculation also has a scope. Monetary results describe consequences under particular exchange conditions and rights. They do not add different people’s satisfactions into a common measure or establish physical feasibility.
ECO.1:3 - Forces
The calculation must be simple enough to use but faithful to the alternatives actually open. Prices help coordinate heterogeneous resources without collecting everyone’s knowledge. Novel arrangements may have no established price; withholding every decision until they do can be as costly as inventing a market quotation.
ECO.1:4 - Solution
ECO.1:4.1 - Recover the decision and the consequential numbers
Name the actor’s choice, the useful result sought and the period in which resources must be available. Separate alternatives that produce different results or leave different obligations. Reuse the resource and cash-flow account already prepared by MA or FIN.
Follow only numbers whose interpretation can change that choice. For each, ask what it denotes: an offered exchange, a past transaction, a budget allocation, an anticipated future exchange, a forgone alternative or a weight in a model. Recover the quantity, quality, location, time and access conditions that matter. “Steel at 500” is not yet a price for a specified supply.
ECO.1:4.2 - Connect the comparison to feasible exchange and use
For an offered exchange, determine what can be obtained at the stated terms and by whom. A quotation for an incompatible specification or unavailable delivery window cannot supply this plan. A supplier’s offer remains an offer until the relevant commitment is made.
For a resource already controlled, identify the alternative use actually displaced. Its historic cost and its current economic consequence may differ. For a novel resource or arrangement, use a comparable offer only after stating the difference that matters; otherwise retain a conditional value or compare physical alternatives and purposes directly.
Keep a model’s weights attached to its objective and constraints. A shadow price can show which constraint is costly within that model. Calling it money does not establish a buyer, a supplier, an exchange or a right to obtain resources at that amount.
ECO.1:4.3 - Return the comparison that the grounds support
Pass the usable quantities and timing to the existing accounting or financial calculation. State separately any important result that is not represented in the monetary account, such as preserving access for an affected community. The decision may use several criteria and leave alternatives incomparable.
If a missing price could change the answer, choose an attainable next move: seek a relevant offer, propose an exchange through ECO.3, compare a bounded range, or choose from already sufficient physical and purpose-based grounds. Additional investigation is justified by the decision it can change. Stop when the current choice is supported at the needed scope, including an explicit conditional choice where that is the useful result.
ECO.1:5 - Archetypal Grounding
ECO.1:5.1 - A cheap plan priced in internal credits
In a constructed repair-depot case, purchasing a compatible part costs €90 delivered this week. A spreadsheet values making it internally at 40 machine credits plus €30 of material. It silently treats a credit as a euro, although credits allocate booked machine time and cannot purchase extra time. The machine has no available slot this week.
The practitioner removes the unsupported €70 comparison. A nearby provider offers the required machining this week for €65, using the depot’s €30 material. The usable comparison is therefore €95 for that route against €90 for the delivered part, subject to equivalent fit and warranty. If no matching offer exists, the internal-credit plan remains unavailable this week; solving its allocation model again cannot make it available.
The repair does not reject credits as a scheduling aid. It stops a claim about monetary cost and availability that the credits did not support.
ECO.1:5.2 - A choice without a market quotation
A community can repair one of two paths with the same already available volunteer time. It has no defensible monetary value for each improvement. The group can still choose by access needs and the repair each alternative permits. Reporting that choice as a financial return would add an unsupported claim; postponing it until every benefit has a price would add unnecessary work.
ECO.1:5.3 - A useful marginal value inside a model
A workshop has ten usable machine-hours and demand for up to twelve identical one-hour jobs. Each completed job contributes €30 after the other relevant variable costs; the remaining inputs and commitments permit any of these jobs. The model’s best contribution rises from €300 at ten hours to €330 at eleven and €360 at twelve. A thirteenth hour adds nothing under that demand limit.
Thus €30 is the modeled value of each of the next two usable hours. It helps set the terms worth considering: an available matching offer at €20 per hour would leave €10 more per added job. The modeled value itself does not supply that offer or make another operator available. A changed demand limit, job mix or needed complement requires a new calculation of the affected margin. The workshop can keep the conditional comparison without investigating every possible capacity supplier.
ECO.1:6 - Bias-Annotation
A convenient numeric column can acquire more authority than the exchange or constraint it represents. Conversely, criticism of a monetary comparison can become a blanket refusal to calculate. Preserve the useful calculation and repair the unsupported interpretation.
ECO.1:7 - Conformance Checklist
Can the receiver identify what the consequential quantities mean, who can obtain the resources, and when? Does the comparison retain the relevant alternative uses and obligations? Can the receiver distinguish a monetary consequence from a physical constraint or an unpriced concern, and make the next choice without filling in an invented exchange?
ECO.1:8 - Common Anti-Patterns and How to Avoid Them
- A computed price is treated as an available offer. Return to the model’s objective and constraints, then establish the actual supply condition.
- An unpriced consequence is set to zero. Keep it as a separate decision consideration or a stated constraint.
- No complete price system, therefore no action. Use the comparison that the available physical, contractual and purpose-based grounds already support.
ECO.1:9 - Consequences
The practitioner can use calculation without overstating its reach. Some rankings become conditional; some apparently cheap alternatives disappear because they cannot be obtained. A limited calculation can still be enough to act.
ECO.1:10 - Architectural Rationale
An economic comparison needs both a method of calculating and a basis for interpreting its inputs. Separating those contributions preserves mathematical and accounting methods while making missing exchange conditions visible. A universal score of social value would require grounds that ordinary monetary calculation does not supply.
ECO.1:11 - SoTA-Echoing
Mises, Economic Calculation, §2 is the historical anchor for comparing heterogeneous productive means through exchange relations, and for the limits of money calculation outside those relations. This pattern adapts that issue to a bounded working decision; it does not infer that every choice lacking a market price is impossible.
The competing move is to optimize with assumed weights. That remains useful for conditional planning: the output is a consequence of those assumptions. The added operation here tests whether the assumption can support the receiving economic claim. Reopen the comparison when access, exchange terms, available alternatives or the use of the model changes.
ECO.1:12 - Relations
MA.1 constructs the resource-and-cost account; FIN.6 compares investments using grounded cash flows. ECO.1 supplies the interpretation and attainable exchange conditions they need when those are disputed. ECO.2 responds to changed prices; ECO.3 can form a previously unavailable exchange. C.11.DUA helps choose whether resolving a remaining uncertainty is worth its attainable contribution.
ECO.1:End
ECO.2 - Reconsider Resource Use in Response to Price Signals
Type: Method pattern Status: Stable
ECO.2:1 - Problem frame
Use this pattern when a changed price or offer can alter how you use, substitute or supply a resource. Begin by identifying the exchange whose terms changed. Compare the feasible response with keeping the present plan. The useful result is an adjustment, or a reason to leave the plan unchanged, with the condition that would change that answer.
A complete account of why the market changed is needed only when it affects the response. A routine purchase already covered by an adequate operating rule can stay with that rule.
ECO.2:2 - Problem
A firm can continue wasting a newly scarce input because its internal numbers are stale. It can also overreact to a price that applies to another grade, quantity or delivery date. Waiting for a complete causal explanation can delay an otherwise useful substitution; responding to an irrelevant quote can create a worse plan.
ECO.2:3 - Forces
A price condenses information beyond one participant’s knowledge but omits many facts relevant to a particular use. An inexpensive operational adjustment and an irreversible investment need different support. Deliberately maintained access or service obligations can outweigh the cheapest purchase.
ECO.2:4 - Solution
ECO.2:4.1 - Establish the changed exchange
Compare like terms: unit, specification, quantity, time, location, payment and access. Determine which part changed and which obligations already fix the price for the current work. Include a consequential service or supply condition even when the quoted money amount stays constant.
Ask whether the change applies at the margin of the contemplated action. A cheaper bulk offer may require more storage than is available. An average historic price can be irrelevant to the next attainable unit. ECO.1 supplies a missing interpretation.
ECO.2:4.2 - Construct feasible responses
Use knowledge of the actual work to consider the responses that could matter: use less per result, substitute another input, change timing or output, increase supply, or keep the present use.
Carry each response through its material complements. A replacement input can require another tool, skill, inspection or delivery arrangement. Price alone cannot establish that the substitute performs the needed function. If the substitute’s function is unresolved, use SYSE.9 to obtain and apply the needed specialist result—for the packaging case below, whether the insert protects the product under its handling conditions. OPS.14 compares the operating alternatives and their transition costs; MA.1 constructs a missing resource-use account; FIN.6 supplies an investment comparison when the response entails a longer commitment. Use only the contribution the present decision lacks.
Compare the attainable net effects over the relevant period, including transition and forgone uses. Retain differences in performance and affected interests alongside the monetary comparison.
ECO.2:4.3 - Match the response to what remains unknown
For a small reversible change, an applicable current offer and adequate functional account may suffice. For a dedicated plant or long commitment, ask which uncertainty about persistence, access or substitution could reverse the decision. Seek only the information that can change that commitment, or retain a conditional plan.
A price rise can arise from supply loss, demand growth, altered quality, taxes or market power. Identifying the cause matters when it changes the chosen response; otherwise the current attainable terms can already justify using less or substituting. Return the chosen response and the event that would reopen it, in the ordinary working plan.
ECO.2:5 - Archetypal Grounding
ECO.2:5.1 - A substitute becomes worthwhile
A constructed packaging case has two qualified alternatives. The present insert uses two units of material at €3 each. Another uses 1.5 units of a different material at €4 each and adds €0.50 of handling per package. All other relevant costs and performance are supplied as equal. The present choice costs €6; the alternative costs €6.50.
A current matching offer raises the first material to €4 per unit. Its cost becomes €8, so the alternative saves €1.50 per package before a €150 changeover. For a confirmed order of 200 packages the expected saving is €300, or €150 after changeover. The practitioner can select the substitute without first explaining the whole price movement.
If only 50 packages remain before an already contracted cheaper delivery, the saving is €75 before changeover, so the same observation supports keeping the present setup. With these unchanged conditions, 100 packages is the monetary break-even point: €150 / €1.50. At that quantity, other consequences can determine the choice. If the substitute is not qualified for the product, its required qualification is part of the comparison.
ECO.2:5.2 - A price has a different scope
An electricity contract fixes the price for today’s shift. Tomorrow’s spot-price spike does not itself change that contractual payment. It may still change the opportunity to sell stored energy or the terms of future work. The practitioner identifies that separate exchange before moving production.
ECO.2:6 - Bias-Annotation
The newest number attracts attention even when it does not apply. A preferred technology can also make its transition burden disappear from the comparison. Retain the available incumbent and identify the exchange and work conditions under which each alternative matters.
ECO.2:7 - Conformance Checklist
Is the changed offer applicable to this action? Do the considered responses remain feasible with their complements and obligations? Can the receiver explain why more information about the cause would, or would not, change the present commitment?
ECO.2:8 - Common Anti-Patterns and How to Avoid Them
- Every price movement requires a market investigation. First test the feasible response already supported by the available terms.
- A cheap input is treated as a cheap result. Carry substitution through performance, complementary work and transition.
- Internal historic prices hide a changed external opportunity. Recalculate the consequential next use rather than replacing every accounting number.
ECO.2:9 - Consequences
Resource use can adapt to dispersed changes without one participant understanding their entire history. The method can also justify inaction. It does not establish that the resulting prices represent every affected interest.
ECO.2:10 - Architectural Rationale
A price-mediated adjustment uses local knowledge of possible responses together with terms formed beyond that locality. This is a division of reasoning as well as of production. The chosen commitment determines how much of the remaining uncertainty must be resolved.
ECO.2:11 - SoTA-Echoing
Hayek, The Use of Knowledge in Society, §§V–VI supplies the historical account of adjusting to a scarcity signal without knowing its complete cause. The pattern adopts that economy of knowledge while requiring the signal to fit the actual exchange.
A detailed market model is the stronger rival when the decision depends on future price formation. For a bounded substitution its extra work can add nothing to the present choice. Neither route assumes that current prices perfectly represent scarcity, power or unpriced effects. Reconsider when the relevant offer, functional substitution or commitment horizon changes.
ECO.2:12 - Relations
ECO.1 restores a disputed calculation basis. ECO.3 explores a new exchange when existing offers no longer serve the plan. OPS.14 supplies a bounded operating comparison, MA.1 a resource-use account and FIN.6 an investment comparison. SYSE.9 obtains and applies a specialist engineering result when functional suitability remains unresolved. ECO.10 is needed when lower unit cost may change the total volume of activity.
ECO.2:End
ECO.3 - Discover an Exchange between Different Plans
Type: Method pattern Status: Stable
ECO.3:1 - Problem frame
Use this pattern when a need, available resource or possible combination is visible, but the parties’ current plans do not yet connect through a workable exchange. Start with the concrete contributions each party can provide and the result each seeks. The result is a proposed exchange that each can use, a conditional proposal with its remaining condition, or a specific incompatibility worth redirecting.
Use an existing satisfactory exchange directly. This method is useful when the missing contribution is discovering the terms or combination, rather than placing an ordinary order.
ECO.3:2 - Problem
Different participants can possess complementary knowledge and resources without recognizing a useful combination. A technically elegant offer can fail because its timing, risk or required change does not fit another party’s plan. A spreadsheet which compares only existing products leaves this possibility outside its alternatives.
ECO.3:3 - Forces
Learning enough about other plans takes work and may expose private information. The parties need not share an ultimate purpose, and their gains need not be measured on one common utility scale. Apparent gains can disappear when transport, assurance, timing, intermediary work or effects on others are included.
ECO.3:4 - Solution
ECO.3:4.1 - Recover the relevant parts of the separate plans
Identify what each prospective party is trying to accomplish, what contribution is missing, and what it can actually offer. Ask for the part that can change the proposed exchange: a delivery window, usable specification, spare capacity, right of access, complementary skill or limit on exposure.
Keep understanding and agreement separate. A party may understand a proposal and rationally prefer its current plan. Avoid treating silence as a commitment or declared interest as available resources.
ECO.3:4.2 - Construct the combination and terms
Form a concrete proposal: who provides what, to whom, when, under which conditions and in exchange for what. The combination may change the product, service, counterparties, sequencing or ownership of a result. Money can mediate the exchange, but barter, reciprocal service and conditional access can also be candidates.
For each party, compare participation with its feasible alternative. Include the work of discovering, arranging and sustaining the exchange, including an intermediary’s contribution. Use ECO.1 for disputed quantities. A difference in valuations can enable trade; agreement on one objective is unnecessary.
Follow the proposal through the complements needed to realize it. Name unresolved supplier, customer, performer or funding commitments for ECO.4. Identify materially affected nonparticipants and resource consequences. Consent between the prospective parties alone does not settle imposed costs or rights of others.
ECO.3:4.3 - Test the contribution, then keep or change the proposal
Use the smallest attainable interaction that can change the next move: a discussion of terms, a matching offer, an illustrative sample, a conditional order or a limited use. A test has a purpose such as “can this party use the service in that window?” rather than “collect more evidence”. STR.7 helps decide whether such a test is worth its burden and how to bound it.
If the proposal is understood but not attractive, change the combination or counterparties, or stop. If it is attractive but a contribution is unavailable, return that condition rather than announcing an exchange. If an adequate attainable agreement already exists, proceed using the ordinary operating and contractual methods.
Return the next usable result in the working proposal. Preserve what the unsuccessful attempt revealed about another plan when it can improve the next search. Wider problematization and search remain with the existing FPF and Strategy methods.
ECO.3:5 - Archetypal Grounding
ECO.3:5.1 - Unused capacity meets a different delivery need
In a constructed case, a courier’s return trip has capacity but leaves at 18:00. A bakery pays €70 for a separate 16:00 collection and initially rejects the courier’s €35 offer. Comparing money alone would misread the rejection: the bakery needs the goods removed by 16:30.
A nearby chilled store has staff and a cooled van available. Its €15 offer covers collection from the bakery at 16:00, arrival at the store by 16:15 and storage until the courier collects at 18:00. The store is responsible for the agreed temperature from bakery pickup until that handover; the courier then maintains it and delivers to the receiving café by 19:00. Both the original €70 service and this combined route meet the café’s delivery window and temperature requirement. The bakery’s outlay becomes €50, saving €20 per delivery before any additional cost of arranging the combination. The store and courier accept these terms and have the needed capacity in this constructed case.
The outcome is a three-party proposal that can now be committed and scheduled. It remains conditional if the store’s temperature control or the handover responsibility is unresolved. If storing the goods damages their quality, the proposed saving does not rescue the combination.
ECO.3:5.2 - A useful disclosure produces no trade
An engineer offers unused evening machine time to another workshop. The workshop needs an operator whom neither party can supply. Naming that missing complement changes the next search: find a qualified operator or choose another arrangement. It does not support reporting the machine time as sold.
ECO.3:6 - Bias-Annotation
Enthusiasm for mutual gain can hide asymmetry, unavailable contributions or effects imposed on outsiders. Conversely, treating preferences as fixed product requirements can hide the possibility of a different useful combination. Keep actual alternatives and changeable proposal terms visible.
ECO.3:7 - Conformance Checklist
Can each prospective party recognize its contribution, expected result and alternative? Are the material complements, intermediary work and remaining commitments visible? Does the stated result distinguish a discovered possibility, a conditional proposal and an available exchange?
ECO.3:8 - Common Anti-Patterns and How to Avoid Them
- A lower price is assumed to settle rejection. Recover the part of the other plan that the offer does not serve.
- Discovery is described as resource-free. Include the real search, arrangement and provision work.
- Mutual consent is treated as a complete assessment. Retain affected rights, shared resources and nonparticipant consequences.
ECO.3:9 - Consequences
A previously absent option can become available for later calculation, commitment and operating work. Failed proposals can yield useful knowledge. The method offers a way of constructing and checking an exchange; it cannot guarantee that one exists.
ECO.3:10 - Architectural Rationale
Economic discovery changes the set of alternatives rather than only ranking supplied alternatives. The reusable operation connects distinct plans through concrete reciprocal contributions. Generic search is still needed when this local construction does not produce a workable answer.
ECO.3:11 - SoTA-Echoing
Huerta de Soto’s account of entrepreneurship and dispersed practical knowledge in The Austrian School: Market Order and Entrepreneurial Creativity, chapter 2, is a historical conceptual anchor. This pattern adapts the connection among different plans; actual discovery and provision retain their resource requirements.
Foss, Klein and Murtinu (2025) extends the resource-mobilization question under uncertainty. The adopted contribution is to include acquiring complementary commitments, not just spotting an opportunity. When no affordable complete offer is available, requesting more quotations for the original specification is a serious alternative. It can find another service without arranging new relationships. Steps :4.1–:4.2 instead recover which part of each plan can change and construct complementary contributions: in :5.1, storage with collection makes the later return trip usable. This choice adds the work of finding a participant, agreeing handovers and sustaining the arrangement. Prefer it only when the resulting advantage warrants that burden; an adequate complete offer can remain better. The example demonstrates the distinction under stated conditions, not a measured superiority of entrepreneurial discovery. Standard purchasing remains the cheaper route when the needed combination and terms are already available. Reopen when a party’s purpose, feasible alternative or complement changes.
ECO.3:12 - Relations
ECO.2 can reveal a changed exchange opportunity; ECO.1 grounds a comparison. ECO.4 forms complementary commitments. ECO.5 addresses private information; ECO.6 addresses dependence after dedicated investment; ECO.7 handles an affected shared resource. STR.7 helps choose and design a bounded experiment for a consequential uncertainty. When a different combination is needed, FPF C.39 develops a way to obtain the result and C.40 develops further search from reusable material.
