Child grants and time use of single parents in South Africa
研究了南非儿童补助金对单亲父母时间分配的影响，发现补助金减少了市场生产劳动时间，但增加了家务和照料时间，导致总工作时间上升，尤其对单亲母亲影响更大。
Abstract This paper is the first to evaluate the gendered effects of child grants on patterns of time allocation across SNA (System of National Accounts) production work, household maintenance, care work, leisure, self-care, and other non-work activities. Using the 2010 South Africa Time Use Survey, I estimate time allocation patterns for grant-eligible single parents aged 20–54. I address the endogeneity of the key grant receipt parameter using a probit model with an originally-constructed instrumental variable, regional median travel time to the welfare office. I find that single parents living in grant recipient households reduce SNA production work. Single parents primarily redistribute their reduced SNA production work time to household maintenance and care work. This rise in household maintenance and care work leads to an overall increase in total work time, especially of single mothers.
