There is a sizable literature on grandparents who provide care for their grandchildren in developed and developing countries, but little research on the economic investments that grandparents make in their grandchildren. In this investigation, we used a sample of older adults in rural China to examine direct monetary transfers made by grandparents for the benefit of their grandchildren. Relying on theories of altruistic and patrilineal preferences, we examined financial transfers made by 831 grandparents to grandchildren in the families of 1,634 parents. Results revealed that the greatest contribution went to grandchildren for whom grandparents provided full-time care because their parents were labor migrants. This finding was net of remittances received, suggesting that personal resources of grandparents were being contributed. In addition, transfers to grandchildren fully followed the male-lineage, with the greatest contributions to grandchildren in grandson-dominated families whose parents were first-born sons. Taken together, these findings support altruistic motivations of grandparents within the context of a strong patrilineal system.
