The International Propagation of News Shocks
Bibliographic record
Abstract
We address the question of business cycle co-movements within and between countries. We first show that for the U.S. and Canada as well as for Germany and Austria, a stock market innovation in the large country, that does not affect Total Factor Productivity in the short run, does indeed explain much of Total Factor Productivity changes in the long run. We therefore label such a shock a news about Total Factor Productivity of the large country. This shock is shown to act as a demand shock in the data, creating a boom in the large country as well as in the small one. Second, we propose a two-country-two-sector model that is shown to give realistic quantitative predictions. The model builds on the closed economy model of Beaudry and Portier [2004], in which there are limited possibilities to reallocate factors between investment and consumption good sectors. We also show that a canonical Real Business Cycle two-country model cannot account for those responses to technological news shocks we have identified in the data.

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.
