Abstract
Most decisions regarding the labor market are not taken by individuals alone but jointly by couples or households. This chapter presents insights from behavioral and experimental economics, biology, and anthropology to understand what shapes these decisions. It specifically focuses on results from a recently growing literature that has been conducting experiments involving multiple household members to study their decisions. The first part presents three behavioral dimensions that are important to consider when studying decisions within households: (1) the nature of the returns that are at stake for the couple, which concerns, for example, whether salaries are monetary or of other kind, (2) differences in individual preferences between household members and especially men and women, and (3) the approach to bargaining by the different household members. The second part discusses theoretical models commonly used in household economics and what results from experimental studies can tell us about them.
