Parents save money to protect their children from financial uncertainty, known as dynastic precautionary savings. By studying parent-child pairs, researchers found that when a child's income is uncertain, parents spend less. This effect is similar to how parents adjust their spending based on their own income risk. A model was used to analyze how this type of saving affects wealth transfer between generations and how policies like universal basic income could impact it. The study also looked at how parents and children interact strategically when it comes to saving for the future.
