Abstract

fetched live from OpenAlex

Are uncertainty shocks an important source of post WWII business cycle fluctuations? The evidence we present in this paper suggests they are. Using both the traditional measure of uncertainty – the stock market volatility index – and a new one- based on the number of New York Times ’ articles on uncertainty and economic activity- we demonstrate that these shocks generate short sharp recessions and recoveries. Output, employment, productivity, consumption and investment all decrease in response to an unanticipated rise in uncertainty. Moreover, we find that wide spread changes in the level of uncertainty captured by our new newspaper index can account for between 10 and 25 percent of the short-run variation in these variables.

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.
