The attainment of financial independence is a key marker of the contemporary transition to adulthood. In this study we ask, how do young adults gain the capacity to support themselves? We contend that communication about work in the family during adolescence is an important precursor of economic self-efficacy during adolescence, which is positively associated with financial independence in early adulthood. Drawing upon rich longitudinal data that span adolescence and young adulthood, we first ask whether family communication and socialization practices surrounding work and finances influence the development of ways of thinking about oneself that imply self-reliance and confidence in the economic domain (economic self-efficacy). Second, we assess whether economic self-efficacy, measured during adolescence, has a long-term influence on the transition to adulthood, status attainment, and financial independence. Our findings indicate that direct communications about work with parents foster the development of economic self-efficacy. This positive dimension of the self-concept fosters achievement during the transition to adulthood (e.g., educational achievement, employment status, and income attainment), which, in turn, heighten financial independence in early adulthood.
