By its definition, care is not (financially) reimbursed. However, care recipients often provide material and/or financial support to their carers, which may be related to a range of psychological and social outcomes, such as the financial fragility of care recipients, changes in the quality of relationships and care, or psychological burden. In this article, I provide a brief overview of the extant knowledge on the topic and discuss some of the research questions that should be addressed in the future, both through analyses of longitudinal data and through focused research projects, linking them to the aforementioned outcomes and overall well-being of the carers.
