Notes: All estimates in this table use the first difference between the current and prior birth admission. Column 1 shows means for the current birth. All mothers in the sample moved across bases between births. Column 2 shows IV estimates of the effect of a change in off-base admission between the current and prior birth. Possible values for the change in off-base are 1 (for a change from on to off-base), 0 (for no change), and −1 (for a change from off to on base). This specification includes an indicator for whether the prior birth took place off base. The change in admission location is instrumented with the change in proximity to a MTF hospital, with possible values 1, 0, and −1. Columns 3 and 4 show IV estimates where the two types of change in off-base admission are estimated separately, and are instrumented with indicators for a move from MTF hospital to no MTF hospital, or from no MTF hospital to MTF hospital. βb is the coefficient on an indicator for off-base admission when the previous admission was on-base, while βd is the coefficient on an indicator for on-base admission when the previous admission was off-base. All regressions include controls for calendar year, age group, sponsor’s pay grade and occupation, and sponsor’s race. Standard errors are clustered at the base level.
