More than 80% of Italian men aged 18–30 live with their parents. We argue that one contributing factor to this remarkably high rate of cohabitation is parents' tastes for coresidence. In order to investigate the role of parental preferences, we estimate the effect of exogenous changes in parental income on rates of cohabitation in Italy using Survey of Households' Income and Wealth (SHIW) micro data from 1989 to 2000. In order to identify a source of exogenous variation in parental income, we use changes in fathers' retirement age induced by the 1992 reform of the Italian Social Security system as an instrumental variable for parental income. By raising retirement age, this reform forced some fathers to remain in the labor market longer than they would have otherwise, therefore raising their disposable income. We use a two-sample instrumental variable (TSIV) strategy. Our TSIV estimates indicate that a rise in parents' income significantly raises the children's propensity to live at home: A 10% increase in annual parental income results in approximately a 10% rise in the proportion of men living with their parents. Although we cannot definitely rule out alternative interpretations, these results are consistent with our hypothesis that cohabitation is a normal good for Italian parents.
