Notes: Each column represents an IV regression where “Got Results” is instrumented with having any incentive, the amount of the incentive, and distance from the HIV results center. Standard errors are clustered by village. Also includes age and age squared, a simulated average distance to the VCT tent, a gender dummy, log expenditures at baseline, years of education, a dummy for being married, and district fixed effects. Columsn 3,4, 7, 8, 11, and 12 present IV ordered probits where “don't know” responses are coded as either some likelihood or are missing values, as indicated above. Coefficients are marginal effects reported as the probility of believing there is no likelihood of infection. In these columns, “Got Results” is instrumented with the same set of instruments as indicated above. Robust standard errors in brackets.
