While a large body of literature documents the existence of informal arrangements to share risk across and within households, there has been little research on the various coping strategies through which risk sharing takes place, and how these strategies function. This study attempts to fill this gap in the literature and examine whether, and to what extent, individual labour-supply behaviour is one of such coping strategies used by households facing risk. Our hypothesis is that, as with a small business, individuals adjust their employment behaviour in the event that one of their household members experiences a variation in their labour supply, that is, either gains or loses a job. Using a unique dataset that collects employment histories for each family member in Tanzania, our results confirm our hypothesis and show that the labour supply of the household members is an important
determinant of employment transitions, and that these effects are greater for women than for men. In the context of low-income countries, we interpret these findings as evidence that the household works as a risk-sharing institution built around women’s labour supply.
