[i] Notes: Each coefficient reported is the estimated discontinuity in the daily number of logged births at the threshold as a result of the PPL scheme. The “m” in each column heading stands for months, and represents the number of months on each side of the threshold. Each coefficient is from a different regression. Robust standard errors are in parentheses.

[i] Notes: Data on each outcome was provided by the Australian Bureau of Statistics.

Means and standard deviations (in parentheses) are presented.

[i] Notes: The coefficient reported is the estimated discontinuity in Baby Bonus Receipt as a result of the PPL scheme. The “m” in the column heading stands for months. An observation is the outcome rate for a 1-month age cell. Controls include the percentage of mothers in each age cell that are Australian born, the average age of the mother in each age cell, the average age of the partner in each age cell, and the percentage of mothers with one child in each age cell. Estimates are weighted by the population, and robust standard errors are in parentheses.
