Objective: The objective of this paper is to describe how and why soci
oeconomic impact assessments, as applied to HIV/AIDS in developing cou
ntries, have evolved over time and to discuss the direction that this
field should be taking in the future. Design: This paper involves a re
view of existing literature and incorporates the experience of AIDSCAP
/Family Health International, the AIDS and Economics Network (AEN) and
other organizations working in this field. Results: Socioeconomic imp
act methodologies have become more rigorous over the last 10 years. Co
ncurrently, they have been applied to achieve a new understanding of t
he impact of AIDS on the economy. The results have been successfully u
tilized because they are often compelling; to inform, sensitize and mo
bilize policymakers. At the same time, however, demand is growing for
socioeconomic impact assessments to continue to evolve to meet the nee
ds of policymakers in developing countries. Conclusion: The tools that
have been used in the past for performing socioeconomic impact assess
ments will have to change significantly to reflect the needs of policy
makers for more specific, policy-oriented analyses. Existing economic
impact assessments in the field of HIV/AIDS will need to be replaced b
y more targeted economic research intended to encourage the developmen
t of appropriate workplace policies, mitigate the impact of HIV/ AIDS
on families, and address critical treatment issues. (C) 1998 Lippincot
