Economic Output & Distribution Laws

← Back to Domain-Specific Families

Abstractions about comparative advantage, gross output, informal production, sectoral cost growth, and empirical regularities in productivity or publication.

5 abstractions in this family — domain-specific abstractions that sit near one another in structural-signature space (k-means over structural-signature embeddings). Each is shown with its short description.

• Absolute Advantage — A per-good comparison of output per unit input between two producers — establishing that productivity differences exist (the precondition for gains from trade) while deliberately not settling who should specialize in what.
• Baumol's Cost Disease — Explain why labor-intensive sectors with little productivity growth become relatively more expensive as wages rise with productive sectors through a shared labor market while stagnant-sector output per worker does not.
• Gross Domestic Product — Compress a whole economy's heterogeneous output into one scalar by summing the market value of final goods and services produced within a geographic boundary over a fixed period, cross-checked by three coincident production, expenditure, and income identities.
• Informal Economy — Economic activities by workers and units that are, in law or practice, not covered or insufficiently covered by formal arrangements, spanning both informal enterprises and informal jobs.
• Lotka's Law — The bibliometric regularity that the number of authors producing exactly n papers is roughly proportional to 1/n², so a small prolific head accounts for most output and a vast single-paper tail contributes little — characterizing a field by a fitted exponent, not an average.
