Does Wright's law trace cleanly to T.P. Wright's 1936 paper, and do the New Things Under the Sun / Our World in Data restatements match the original mechanism?

capture promoted 2026-09-05 · economics, wrights-law, learning-curve, experience-curve, tp-wright-1936
Wright's own 1936 formula is a power law of cumulative production quantity, log-log linear — not a function of calendar time

Wright's 1936 paper reports four distinct learning curves, not one flat 80% — the whole-airplane composite rises from 83% to 90% as quantity scales

claim seedling Tier 1 2026-09-05 · economics, wrights-law, learning-curve, tp-wright-1936, cost-curves
Wright's own '80% curve' is defined over a whole production lot's average cost, not an individual unit's cost — a distinction the modern restatements drop
