We studied the effect of health events (accidents and chronic diseases) on the occupation probabilities at the individual level, while accounting for both correlated individual and time effects. Using difference-in-differences with exact matching estimators, we found that health events have a strong impact on individual labor market histories. The workers affected by a healt event have a stronger probability of entering inactivity and a lower probability of keeping their jobs. We also found that the less qualied workers, women, and workers with short term jobs are the most negatively affected by health events.
