Respondents could redeem their vouchers only after hearing their results. Those who were HIVpositive were referred to the nearest permanent clinic for further counseling. Those who were
positive for other sexually transmitted diseases were also given free treatment at that time, which
may have provided additional incentive to attend VCT centers, over and above the monetary
incentive. However, STI prevalence rates were very low (see Table 2, panel B).
Approximately two months after results were available, respondents who tested for HIV in
two districts, Balaka and Rumphi, were reinterviewed in their homes by interviewers who had no

single condom. Respondents were allowed to purchase condoms only from the 30 cents they had
just been given in order to prevent condom purchases from being correlated with any monetary
incentive received two months prior at the results center. The maximum number of condoms that
could be purchased was 18.
C. Sample Attrition and Test Refusals
The sample used for the main analysis in this paper consists of 2,812 residents of rural Malawi
who accepted an HIV test, who had provided basic demographic data during the 2004 survey (age, village location), and whose HIV test result was not indeterminant (14 individuals).
Although the original sample in 1998 was randomly drawn, sample attrition across waves of
data collection affects the degree to which this sample...
