The household is a critical decision-making and consumption unit and various crucial decisions are indeed made within households. These include decisions on day-to-day expenditures, decisions about where to live, who to live with, who should work and how to raise income, as well as where children should attend school, and how to spend the available income. However, perceiving the household as a single ‘glued-together’ unit, whose interests are as that of an individual, suggests that investigations into intra-familial issues are unnecessary, thus neglecting what actually happens within households. Employing resource theory and the theory of assortative mating in the application of the cooperative intra-household bargaining model, the current study examines the sources of bargaining power that informs financial decision-making processes by females within co-resident couples. The study also determines how bargaining power and financial decision-making of female partners in co-resident couples impact on family-type public goods expenditure.
