This dissertation investigates several drivers of intergenerational mobility. The first chapter examines how returns to colleges and majors, admission policies, and student sorting affect intergenerational mobility. I study this question in Denmark, where tuition-free colleges and generous living grants provide an ideal setting to investigate the sources of inequality that remain in the absence of financial constraints. Leveraging GPA admission cutoffs from a centralized matching algorithm, I apply a regression discontinuity design to examine whether students from low socioeconomic status (SES) benefit from selective degrees (college-major pairs). Scoring just above the cutoff for admission to a more selective degree raises low-SES students' income by 9% at age 30, partially closing the SES wage gap. I develop a joint model of degree selection and labor market outcomes, to disentangle the contribution of degree-specific returns from that of students' degree choices as sources of inequality. The model accounts for the impact of degree peer composition on outcomes. Estimates from the model reveal that returns to degree enrollment are higher for low-SES students than for high-SES peers across the distribution of degree selectivity. Furthermore, I find that the current GPA-based meritocratic admissions system is inefficient in terms of maximizing long-term earnings. Implementing need-affirmative admissions could reduce the SES wage gap by 15% through upward mobility of disadvantaged students, without adversely impacting displaced high-SES students. Notably, the SES wage gap could be eliminated if students selected degrees based on expected earnings returns. The second chapter studies households’ willingness to pay for neighborhood and school attributes. In Denmark, education at all levels is tuition-free. Teacher salaries and expenditures on schools are mandated to be equal. Yet there is substantial variation in teacher quality and student performance across neighborhoods around schools for which parents pay in terms of housing prices. Homophily--sorting by parental education and income into neighborhoods with different peer, teacher and housing attributes explains this phenomenon and not the sorting by preferences for school quality and tax expenditure emphasized in many models of local public goods. Parents buy packages of attributes and not just school quality, which is the emphasis in much of the literature. We develop and apply multiple approaches to identifying parental valuation of measured school quality in the presence of strong neighborhood sorting. Finally, the last chapter examines whether growing up in a better neighborhood has positive consequences on long-term labor market outcomes and educational attainment. We exploit a unique spatial dispersal policy that randomly resettled refugees across neighborhoods in Denmark from 1986-1998. We find that a higher quality neighborhood--as measured by the wage outcomes of children already living there--is significantly associated with increased market income in adulthood. Our mediation analysis reveals that the effect of neighborhood quality on child adult income is fully mediated through the impact of assigned neighborhood on parental income.
