Multivariable regression results from a difference-in-differences analysis. Column 1 and Column 2 show results based on a linear probability model and logistic regression model respectively. Although not shown in the table, the models control for an indicator of Namibian villages adjacent to Phase I Angolan areas at baseline. Constant terms from the two models are also not shown in the table. Data for this analysis is restricted to Namibian households surveyed at baseline and midline
95% confidence intervals shown in parentheses are based on Huber’s cluster robust variance estimator
*** p < 0.01, ** p < 0.05, * p < 0.1
^aAll Namibian villages were treated between baseline and midline, which means that the post indicator captures both time and treatment effects
