Bargaining with Grandma: The Impact of the South African Pension on Household Decision-Making
利用南非养老金年龄断点，研究发现符合条件的女性成为家庭主要决策者的概率提高15个百分点，而男性无此效应，这与女性收入份额增加相关。
Abstract I examine how an exogenous change in individual income affects decision-making in the household. Using the age discontinuity in eligibility for the South African pension, I find that eligible women are 15 percentage points more likely to be the primary decision-maker in the household than noneligible women. This corresponds with a large increase in their share of household income. There are no parallel effects for men. Due to labor force withdrawal, male income does not increase with eligibility, suggesting that their status in the household is unchanged.
