Abstract
This paper examines the local economic impact of Yanacocha, a large gold mine in Northern Peru. Using annual household data from 1997 to 2006, we find evidence of a positive effect of the mine's demand for local inputs on real income. The effects are only present in the supply market and surrounding areas, and reach unskilled workers in non-mining sectors. Consistent with a general equilibrium framework, we also find an increase in the local price of nontradable goods. Taken together, our results underline the potential of backward linkages from extractive industries to create positive spillovers in less developed economies. (JEL L72, O13, O18, Q32, Q33, R11)

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
