Vox EU: Using historical newspaper data to deal with measurement error

Vox EU: Using historical newspaper data to deal with measurement error. “Researchers typically collect newspaper-based data for use as outcome, treatment, or control variables in statistical analysis. This column argues that data generated from historical newspaper articles can also be used as a low-cost alternative for resolving measurement errors. The authors illustrate their framework by replicating two recent studies of how the boll weevil – a beetle that infests cotton crops – affected economic outcomes in the US South from 1892 to 1922.”
