The current study examines sources of bargaining power that inform financial decision-making processes within co-resident couples and determines how bargaining power and decision-making impact on family-type public goods expenditure. The study uses South Africa's National Income Dynamics Study, which offers a direct measure of financial decision-making responsibility. In terms of analysis, probit regression models are used to establish socioeconomic determinants of decision-making for female partners in co-resident couples, while ordinary least squares linear regression models are employed to determine the extent to which financial decision-making responsibility and power influence expenditure on family-type public goods by households. There is evidence of the relevance of economic factors in explaining financial decision-making as postulated by the resource theory. Households with wives who gain a decision-making role spend more on family-type public goods. The findings suggest that policy has to focus on gender mainstreaming and empowerment, which would enhance the decision-making role of women within co-resident couples.

共同居住的南非夫妇的家庭型公共产品和家庭内部决策

目前的研究调查了为共同居住的夫妇的财务决策过程提供信息的议价能力来源，并确定议价能力和决策如何影响家庭类型的公共物品支出。该研究使用了南非的国民收入动态研究，该研究提供了财务决策责任的直接衡量标准。分析方面，采用probit回归模型建立同居夫妇中女性伴侣决策的社会经济决定因素，采用普通最小二乘线性回归模型确定财务决策责任和权力的影响程度。家庭用于家庭类公共物品的支出。有证据表明经济因素在解释资源理论所假设的财务决策方面具有相关性。拥有决策角色的妻子的家庭在家庭类公共物品上的支出更多。调查结果表明，政策必须关注性别主流化和赋权，这将增强女性在共同居住的夫妇中的决策作用。
