The Economic Benefits of Malaria Prevention: A Contingent Valuation Study in Marracuene, Mozambique
Bibliographic record
Abstract
A contingent valuation (CV) survey was conducted in Marracuene Mozambique a very low-income malaria-endemic community about 50 kilometers north of Maputo to estimate adults’ perceived economic benefits of avoiding malaria. Interviews were conducted with 282 individuals in which respondents were asked whether they would purchase a hypothetical malaria vaccine that would prevent malaria for one year if it cost them a specified price. The average respondent’s willingness to pay to avoid the (high) risk of contracting malaria for one year was approximately US$14 equivalent to about seven chickens in the local economy. Their responses to these CV questions suggest that the economic benefits to even very poor individuals are larger than many observers have assumed and that the potential revenues available from low-income rural communities may be substantial. The estimates of the average adult’s willingness to pay for the malaria vaccine are the three to four times higher than estimates based on a simple cost-of-illness approach. (authors)

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
