This paper investigates whether excessive parental alcohol consumption leads to a less altruistic behavior of parents by looking at their time devoted to child care. Using the Russia Longitudinal Monitoring Survey, the study focuses on couples with children under fourteen years of age, for whom we estimate a model of allocation of time, treating market and domestic work supplies as endogenous. We find that husbands’ alcohol consumption has a negative impact not only on their own, but also on their wives’ weekly hours spent in child care. Moreover, husbands’ alcohol consumption negatively affects the amount of domestic work of their wives, but neither their own, nor their wives’ market work. As for wives, their alcohol consumption has no significant impact on either their own or their husbands’ allocation of time. We interpret these findings as a negative impact of alcohol consumption on fathers’ altruism, confirming that, even if drinking is mainly a male issue, the negative effects on the more vulnerable household members cannot be overlooked.
