Notes:Entry into our analytical sample: ID 1 enters the data set in the first quarter of 1981. She starts working in the second quarter of 1981. She will have acquired 1.5 years of tenure at the beginning of the fourth quarter of 1982, when she enters our analytical sample. Exit from our analytical sample: After entering our analytical sample, the woman is working for six quarters and then stops working. Because ID 1 exits the labor market, she leaves our sample. The units of observation are quarters. Thus, ID 1 enters our data set with six observations. Distinction between the treatment and the control group: From the firm identifier, we know that there was a mass layoff in the firm between July 1982 and June 1983 (we only have information on this characteristic of the firm every June of a given year). We assume that the exit from the labor market is due to the mass layoff. Therefore, observation number 13 of this woman enters our analytical sample as a treatment observation. Observations 8 to 12 enter our analytical sample as control observations. Linking employment and fertility: For each single observation, we calculate the cumulated pregnancy probability by the end of years 1, 2, 3, 4, and 5 after the displacement (for the treated cases), and after the “reference quarter” for the control group. These additional five variables are not displayed.
