Survey data underestimates earnings instability, impacting financial security for many.
The study compared different ways of measuring how people's earnings change over time. They found that estimates based on survey data were similar to each other, but different from estimates based on unemployment insurance records. This suggests that survey data might not show the full picture of how earnings change. By looking at both survey and administrative records, the researchers found that differences in earnings changes for people with lower incomes explained a lot of the variation in estimates of earnings instability.
