A white diamond on the axis indicates that the impact is statistically significant at the 10 per cent level. A black diamond on the axis indicates that the impact is statistically significant at the 5 per cent or 1 per cent level. These figures include some months before the time of random assignment. Months before random assignment are indicated with a negative sign
