In this article a model is presented in which the family decides the labour supply of both spouses and their time donations to non-profit organizations. For the estimation, Spanish data was used which showed that family size and pre-school children influence decisions made about time distribution of husband and wife. Women with fewer family responsibilities work longer hours and donate more time, whilst the effect on men is the contrary. Also, monetary donations by the family are directly related to time donations by the spouses.
