This article integrates sociological and economical theory to provide a comprehensive explanation for why parents send money to particular children, and tests more explicit hypotheses on how differences in welfare state provisions can explain divergent patterns between countries. The spending on various welfare domains as a percentage of Gross Domestic Product is used to determine whether inter-generational solidarity is shaped by
welfare state provisions. We use data from the Survey of Health and Retirement in Europe
(SHARE) to analyse the influence of welfare state provisions on the likelihood of intergenerational transfers in ten European countries. The results indicate that parental resources and reciprocity expectations as well as children's need are important determinants of monetary transfers. Although differences between countries are found, they do not seem to justify the distinct division between "the three worlds of welfare" often used in sociological work.
