Stages of Production is an analytical division of production by the connections between inputs and outputs. Menger explains higher-order goods through their indirect relation to satisfying needs. A specific plan requires separate attention to production time, complementary resources and expected future use.
Menger traces fields, grain, flour and bread. Bread directly satisfies the need for food; the other resources contribute indirectly. A good’s order depends on its particular use, not an inherent property independent of purpose. Do not assign an object an immutable place in every plan. [Menger — Principles of Economics, I]
A bakery needs flour, an oven and labor at compatible times. Lachmann distinguishes complementarity within a plan from compatibility among plans. A simple chain misses parallel deliveries; completing one input does not guarantee the others are ready. [Lachmann — The Meaning of Capital Structure]
Mises distinguishes working time from the time a product needs to mature. Several quick operations can take less time than one long maturation phase. Compare plans using actual schedules and waiting, not merely the number of named steps. [Mises — Human Action, XVIII]
In Mises’s analysis, a longer method may yield a more valuable result, but its benefit must justify waiting and committed resources. Adding an operation alone proves no productivity increase. Compare the attainable result with the forgone alternative and the time it becomes usable. [Mises — Human Action, XVIII]
Mises assesses production from the acting person’s current options. Do not mechanically add a ready machine’s entire production history to a plan’s remaining duration. Past manufacture and future waiting are different data; state the starting point for a new choice. [Mises — Human Action, XVIII]
An oven can contribute to many batches of bread while flour is consumed in one. Mises distinguishes production time from a durable resource’s period of service. Do not assume every object passes through the chain once and disappears entirely into a single output. [Mises — Human Action, XVIII]
Menger derives higher-order goods’ value from the expected value of the future product. Today’s selling price for a similar product is not guaranteed when the plan finishes. Separate current observations from expectations; technically completed production can disappoint economically. [Menger — Principles of Economics, III]
Equipment manufacture, installation and provision of a Bitcoin service can belong to different connected plans. This illustrates an economic relationship, not a classification of protocol transactions. Identify simultaneous inputs, availability and intended service; transaction count alone does not measure production stages. [Menger — Principles of Economics, I] [Lachmann — The Meaning of Capital Structure]
