Abstract
killer application of the new framework for productivity measurement presented in this paper is the impact of information technology (IT) on economic growth. A consensus has emerged that the remarkable behavior of IT prices provides the key to the surge in U.S. economic growth after 1995. relentless decline in the prices of information technology equipment and software has steadily enhanced the role of IT investment. Productivity growth in IT-producing industries has risen in importance and a productivity revival is underway in the rest of the economy.The surge of IT investment in the United States after 1995 has counterparts in all other industrialized countries. It is essential to use comparable data and methodology in order to provide rigorous international comparisons. A crucial role is played by measurements of IT prices. U.S. national accounts have incorporated measures of IT prices that hold performance constant since 1985. Schreyer [Schreyer, Paul (2000), The contribution of information and communication technology to output growth: A study of the G7 Countries. Organization for Economic Co-operation and Development, Paris, May 23] has extended these measures to other industrialized countries by constructing internationally harmonized prices.The acceleration in the IT price decline in 1995 triggered a burst of IT investment in all of the G7 nations - Canada, France, Germany, Italy, Japan, the UK, as well as the U.S. These countries also experienced a rise in productivity growth in the IT-producing industries. However, differences in the relative importance of these industries have generated wide disparities in the impact of IT on economic growth. role of the IT-producing industries is greatest in the U.S., which leads the G7 in output per capita.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
