^a and ^b indicate that the estimate is significant at the 0.05 and 0.01 levels, respectively. It is the reported value after multiplying 1000 with the standard errors in the time and treated time and multiplying 100 with the time coefficient of the log hours working time and treated time. The reference group for the unemployment status is the employed and the employment permanent is the reference for the employed temporary
