  1. The outcome variable is in (1) and (2) the SF12 US-weighted physical health measure and in (3) and (4), the SF12 US-weighted mental health measure for the Malawian population. In columns (2) and (4) are the standardised beta-coefficients presented. Model (1) presents findings from the analysis on the 2006 sample. Model (2) presents findings from the analysis on the 2012/13 sample. We control for year and region effects, and covariates. Robust standard errors in parentheses; *** p < 0.01, ** p < 0.05, * p < 0.1
