BACKGROUND Point-of-care CD4 tests at HIV diagnosis could improve linkage to care in resource-limited settings. Our objective is to evaluate the clinical and economic impact of point-of-care CD4 tests compared to laboratory-based tests in Mozambique. METHODS AND FINDINGS We use a validated model of HIV testing, linkage, and treatment (CEPAC-International)(More)

We combine the analysis of spot trading and buyers' disparate private valuations for different suppliers' products, and jointly endogenize the determination of three major dimensions in contract design: (i) sales contracts versus options(More)

Specifically, our approach fully and jointly endogenizes the determination of three major characteristics in contract design, namely (i) Sales contracts versus options(More)
