TL;DR: A procedure by which the coefficient of interest can be extracted "post hoc" from a multiple regression in which all the proxies are used simultaneously, which is strictly superior in large samples to coefficients derived using any index or linear combination of the proxies that is created prior to the regression.

TL;DR: This paper used the Quarterly Employment Survey conducted by Statistics South Africa that allows them to explore how South African enterprises create and destroy jobs, shedding light on many of the policy questions that are relevant in a high unemployment society like South Africa.

TL;DR: In this paper, the authors consider from first principles what sort of index might make sense, given the predominantly dummy variable nature of asset schedules and show that there is, in fact, a way to construct an asset index which does not violate some basic principles and which also has the virtue that it can be used to construct "asset inequality" measures.

TL;DR: The structure of households in rural South Africa is evolving under the pressure of social change and increased mortality due to HIV/AIDS, with no evidence, however, that the social fabric is unravelling or that individuals are becoming increasingly isolated residentially.

TL;DR: In this article, an approach to South African unemployment based on the perspectives of search theory suggests that labour market "ows" are very important and that search and screening costs of employers may explain some of the dynamics of SA unemployment.
