Notes: ∗ p < 0.1, ∗∗ p < 0.05, ∗∗∗ p < 0.01. Robust standard errors (clustered at the household level to account for intra-household correlation) in parenthesis. Regressions are weighted using sampling weights to account for choice-based stratified samples. The Delta method is applied to calculate the statistical significance of the marginal effects.
