In the light of an increasing future demand for long-term care services in ageing societies, families' provision for current and future long-term care needs has been subject to debate. Within this context, there is little discussion about parents' incentives to socialise their children to their own traits to achieve a desired child behaviour. Our study contributes to the literature by analysing to what extent parents transmit filial norms to their children and whether this transmission process affects children's care-giving behaviour if a parent needs long-term care. Using data from the German Family Panel, we initially analyse the transmission of filial norms from mothers and fathers to their children. Second, we examine the importance of filial norms that prevail in the child's local environment. Third, we assess whether an intergenerational transmission of norms transmits into child behaviour if a parent needs long-term care. We estimate linear regression models and account for child and parent characteristics as well as for the living environment. The results show that children have stronger filial norms when both parents report stronger filial norms. But, children also tend to be influenced by average norms in their local environment. Furthermore, children are more likely to provide support to a parent in need when their filial norms are stronger. We conclude that children's filial norms are at least partially shaped via a process of socialisation and that these norms transmit into children's care-giving behaviour if a parent needs long-term care. It is, therefore, important that filial norms that prevail in a society are in accordance with the institutional long-term care system that prevails within that country.
