This file contains analytical code and aggregate data for evaluating the impact of step-downs (reductions in workers' comp payments after several months in the system) on scheme exit, plus the R project file. I have included the cleaning file but no case-level data.

To use:

Download all files into a single folder and open the project file. You should be able to run most RMarkdown files from there. The meta-analysis file depends on outputs from all other analytical files.

Note on v5:

This update reflect analytical changes to reflect peer review and the correction of an existing error. Analytical changes include an additional sensitivity analysis investigating effects on claims unaffected by step-downs, which would indicate confounding. The existing error was exclusion criteria had not been applied correctly in some cases. Claims affected by step-downs must consider both maximum/minimum caps and compensation rates. Otherwise, claims may have minimal effects of step-downs. E.g., if the cap was $2000 per week with an initial rate of 95%, injured workers could only be included if they made $2000 / 95% or less.
