Notes: Column 1 shows coefficients from an OLS regression where the outcome is the change in off-base status from the previous to the current birth for wives of enlisted personnel. The p-value is for an F-test where the null hypothesis is that the two instruments are opposite and equal. The model includes controls for calendar year, age group, sponsor’s pay grade and occupation, and sponsor’s race. Standard errors are clustered at the base level. Column 2 repeats the exercise for wives of officers.
