Abstract

fetched live from OpenAlex

We examine the impact of extreme heat on household labor allocation in Ghana, Mali, and Nigeria using earth observation and microdata from Ghana. We find that extreme heat affects household labor in distinct ways with significant cross-country heterogeneities. In Nigeria, extreme heat reduces labor use at the extensive margin but increases labor use at the intensive margin. Notably, child labor rises while adult labor declines at the extensive margin. In Mali, extreme heat leads to an overall increase in household labor, particularly among women and children, whereas Ghana shows minimal impact except for reduced child labor. Both Mali and Nigeria experience decreases in hired labor, animal traction, and associated labor costs under extreme heat exposure. These patterns could be explained by farmers’ adaptive strategies: extreme heat triggers the build-up of pests, weeds, and diseases, which could induce farmers to use more pesticides and engage in manual weeding, which are labor-demanding. Moreover, households rely on climate-resistant crop varieties and cropland expansion, which may require additional labor. These findings underscore the importance of context-specific adaptation strategies and the nuanced effects of extreme heat on rural labor markets in West Africa.

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.
