We use data from the Panel Study of Income Dynamics (PSID) and multilevel event-history and logistic-regression models to show that the likelihood of leaving home for college is positively affected by the father's education and the parental income. Unlike in previous research, we find evidence for the 'feathered-nest' hypothesis, in that the likelihood of returning home increases with parental incom
