Suppose I am interested in evaluating the impact of [a particular public program] on [some outcome X] in [country Y], say the impact of [Adult Education and Family Literacy Act spendings] on [adult literacy] in [the US].
In an attempt to control for confounding factors, I am interested in learning about other public programs that might also influence outcome [X].
Would a question like "What are public policies that might impact [X] in country [Y]?" be on topic here?
If not, do you think it would be on another SE site?
