Note: This table reports the estimated coefficients and standard errors of “having a first-born son” on nutrition, health and other outcomes. Estimates for control variables are not listed. Nutrition and health data is from CHNS 1993, 1997, 2000, 2004, and 2006. The number of observations is 10,718 for the women sample, 10,101 for the men sample and 8,427 for women with children younger than 18 years old. Household expenditure data is from CHNS 1993 and 1997, with an observation of 4,965 for food, 3,464 for cigarettes, and 3,344 for alcohol. Expenditure share is calculated among the total of food, cigarettes and alcohol. The number of observations with nonmissing data on the expenditure of all three types of goods is 2,398, which is the number of observations for the regressions on expenditure share. The sample used in the regression of labor supply is restricted to people who have a record of working time, with an observation number of 4,845 for women and 5,187 for men. Transfer data is from CHNS 2000, 2004, and 2006, with an observation number of 4,601. Standard errors shown in parentheses are clustered at the household level.
