This article studies labor supply in the extended household (composed of two families living together). The extended household structure affects the incentives to work of household members for at least three reasons: economies of scale, cash transfers between the families living in the extended household, and easier childcare arrangements. We develop a structural model incorporating these components and taking into account the self-selection process into extended households. We then estimate this model with South African data and provide an explanation for the differences in participation rates between nuclear and extended households.

大家庭中的劳动力供给：南非的规模经济、自我选择和家庭内部资源分配

本文研究大家庭（由两个共同居住的家庭组成）中的劳动力供给。大家庭结构至少出于三个原因影响家庭成员的工作积极性：规模经济、大家庭中家庭之间的现金转移以及更容易的儿童保育安排。我们开发了一个包含这些组成部分的结构模型，并考虑了大家庭的自我选择过程。然后，我们用南非的数据估计了这个模型，并解释了核心家庭和大家庭之间参与率的差异。
