Bhorat and van der Westhuizen (2013) use asset indices to explore inequality in post-Apartheid South Africa. We show that the way in which the asset indices were transformed to calculate the Gini coefficients does not preserve the relative ranking of inequality measures on subgroups. This means...

We present a test of the hypothesis that a subset of the regressors are all proxying for the same latent variable. This issue will be of interest in cases where there are several correlated measures of elusive concepts such as misgovernance or corruption; in analyses where key variables such as...

When asset indices are used in regressions the coefficients obtained are typically difficult to interpret. We show how lower bounds on expenditure effects can be extracted, if the relationship between the assets and expenditure can be calibrated on an auxiliary data set.

We show that body mass increases with economics resources among most South Africans, although not all. Among Black South Africans the relationship is non-decreasing over virtually the entire range of incomes/wealth. Furthermore in this groupd other measures of success (e.g. employment and...
