Research on HIV infection and sexual behaviour in sub-Saharan Africa typically focuses on individuals aged 15–49 years, under the assumption that both become less relevant for older individuals. We test this assumption using data from rural Malawi to compare sexual behaviour and HIV infection...

The recent work on misallocation argues that aggregate productivity in poor countries is low because various market frictions prevent marginal products from being equalized.
