These are issues affecting the degree of equality in economic opportunities and the dynamics of earnings inequalities within the labour market. The inferences made about women's decision-making and their varied labour income due to the number of children given birth in South Africa. First, much of the existing literature contends that income is a key determinant of household decision-making. Yet the causal connection between income and household decision-making is difficult to ascertain, given the obvious endogeneity bias that may arise from reverse causality and omitting (unobserved) confounding variables correlated with income and the household decision- making measures. Thus, this study exploited the exogenous variation in household income and their decision-making. This is based on a unique natural experiment in South Africa using age discontinuity in eligibility for Old Age Pension (OAP) income transfer- to identify the causal effect of income on household decision-making. Using a regression discontinuity design (RDD), the study found that women's decision-making responded to changes in income from OAP transfer more than that of men. More so, the OAP transfer influenced women decision-making by 12% points for the recipient more than non-recipient. The results from the quantile treatment effect confirmed that the OAP income transfer effect is heterogeneous across the distribution of household decision-making. The study suggested that women should be used as a channel of distribution of social grant (in development programmes) to reduced inequality and achieve gender equalityen© 2021 University of the Witwatersrand, Johannesburg.
