Experimental Data on Eyeglass Adoption Spillover Effects in Rural Chinese Schools

Rural junior high schools in China provided the setting for a randomized controlled trial on health product adoption. The anonymized replication data supports a study on the spillover effects of providing free eyeglasses to myopic students on their peers. The dataset was authored by Jingchun Nie and last updated on 2026-04 27.

Use Cases

• Analyzing spillover effects of health subsidies based on experimental evidence from a randomized controlled trial.
• Studying social norm mechanisms in health product adoption based on data on peer influence and stigma.
• Evaluating the welfare gains of one-off subsidies based on long-run adoption metrics for non-recipients.

Strengths

• Data originates from a randomized controlled trial, a method noted for causal inference.
• The study examines a specific, quantified spillover effect of 2.4 percentage points.
• Dataset is associated with a paper that includes mechanism tests and robustness checks.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and demographic bias inherent to the rural Chinese school setting.
