Our Objective
Estimate the causal effect (impact) of intervention (P) on outcome (Y).
(P) = Program or Treatment (Y) = Indicator, Measure of Success
Example: What is the effect of a Cash Transfer Program (P) on Household Consumption (Y)?
Causal Inference
What is the impact of (P) on (Y)?
α= (Y | P=1)-(Y | P=0)
Are we done?
Problem of Missing Data
α= (Y | P=1)-(Y | P=0)
For a program beneficiary:
we observe
(Y | P=1): Household Consumption (Y) with a cash transfer program (P=1)
but we do not observe
(Y | P=0): Household Consumption (Y) without a cash transfer program (P=0)
Solution
Estimate what would have happened to Y in the absence of P.
We call this the
Counterfactual.
Estimating impact of P on Y
α= (Y | P=1)-(Y | P=0)
