Abstract

fetched live from OpenAlex

Using a publicly available input-output database that covers 44 countries and 56 industries, I show that most prices are, on average, two to three times higher than the natural costs of production, costs that include a normal rate of return to capital. The novelty in this research is the argument that the true markups are compounded—they incorporate the markups already existing in the intermediate goods and services (inputs) that a company purchases in a vertical chain of production. A complex market structure, one in which companies sell and purchase intermediate products from each other in both horizontal and vertical directions, is the perfect environment for inflating a price well above its natural level. This research may help understanding the true extent of market power. Market power has a substantial impact in such matters as income inequality, standard of living, and economic development. Keywords: complex market structure, compounded markup, monopoly pricing, world input-output tables

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
