Construction of hypothetical gap closing estimates from the ECLS-B
| No program (T=0) | Universal (T=1) | Targeted (T=D) | |
|---|---|---|---|
| Predicted outcome among higher income (D=0) | a0 | a0 + a2 | a 0 |
| Predicted outcome among low income (D=1) | a0 − a1 | a0 − a1 + a2 + a3 | a0 − a1 + a2 + a3 |
| Predicted gap | a1 | a1 − a3 | a1 − a2 − a3 |
| Portion of gap closed (Ca) | a3 / a1 | (a2 + a3) / a1 |
