Abstract: Using SAMOD, a tax-benefit microsimulation model for South Africa, this paper examines the joint distributional impact of the increase in the value-added tax (VAT) rate and increases in benefit amounts in 2018. Although poverty and inequality did not increase overall, the poorest still saw a reduction in their purchasing power, as many of those in the lowest decile do not receive any social benefits. The paper then explores the consequences of eliminating zero-rating in VAT and using the generated revenues to finance new social benefits. The results suggest that a policy package of a uniform VAT and an expanded set of social benefits would lead to reduced poverty and inequality in comparison to the current practice of zero rating of some consumption goods in the VAT. The findings demonstrate the superiority of using direct taxes and benefits as opposed to provisions in indirect taxes in achieving redistribution.

This paper investigates experimentally how changes in wage rates and entitlements affect individual productivity in lab-in-the-field experiments run with married couples from rural regions in Uganda. We design a game in which the production task itself is straightforward, but where the rules governing payment vary across subjects and between rounds. In some cases, all the value of output goes to the husband; in other cases all goes to the wife; in other cases the value of output is shared equally and finally in some cases each spouse receives income according to only their own output. To consider the effects of wage inequality we vary the price paid for each completed item so that the ratio of male to female wages varies from 0.5 to 2. All this is done transparently so that both partners know the rules of the game. The results generally indicate that a rise in relative wages lowers relative effort, a result that is contrary to the most straightforward interpretation of standard models of the household, but compatible with some models of fairness. Men do not generally respond strongly to treatment. In contrast, women's labour supply is strongly backward bending when all income goes to the husband, but effort rises with wages when each spouse gets to keep their own earnings. The results therefore suggest that the effects of reforming or removing one inequality may depend critically on the existence of other inequalities.
