Explaining Cross-Cohort Differences in Life Cycle Earnings
College-educated workers entering the labor market in 1940 experienced a 4-fold increase in their labor earnings between the ages of 25 and 55; in contrast, the increase was 2.6-fold for those entering the market in 1980. For workers without a college education these figures are 3.6-fold and 1.5-fold, respectively. Why are earnings profiles flatter for recent cohorts? We build a parsimonious model of schooling and human capital accumulation on the job and calibrate it to earnings statistics of workers from the 1940 cohort. The model accounts for 99 percent of the flattening of earnings ...

Educational Attainment and Wage Growth in New England: Evidence from Four Decades of Administrative Wage Records
Per capita personal income in New England grew from $10,731 to $87,655 during the 1980–2024 period. This increase, the largest among all US census divisions, coincided with significant growth in educational attainment in the region. As of 2024, 53 percent of New England workers aged 25 to 64 held at least a bachelor’s degree, and 23 percent possessed advanced degrees, compared with national averages of 44 percent and 17 percent, respectively. This study provides new insights into the relationship between educational attainment and income growth in New England, examining both individual ...

Causes and Consequences of Student-College Mismatch
College admissions are highly meritocratic in the U.S. today. It is not the case in many other countries. What is the tradeoff? On one hand, meritocracy produces more human capital overall if higher ability students learn more in college and if they learn more in higher quality colleges. This leads to a higher overall level of earnings (i.e. greater efficiency, loosely speaking). On the other hand, more meritocracy generates a higher degree of earnings inequality. In this paper, we quantify this efficiency-equality tradeoff. Our results suggest small efficiency losses/gains from student ...

Test Questions, Economic Outcomes, and Inequality
Standard achievement scales aggregate test questions without considering their relationship to economic outcomes. This paper uses question-level data to improve the measurement of achievement in two ways. First, the paper constructs alternative achievement scales by relating individual questions directly to school completion and labor market outcomes. Second, the paper leverages the question data to construct multiple such scales in order to correct for biases stemming from measurement error. These new achievement scales rank students differently than standard scales and typically yield ...

Why Are Life-Cycle Earnings Profiles Getting Flatter?
The authors present a simple, two-period model of human capital accumulation on the job and through college attainment. They use a calibrated version of the model to explain the observed flattening of the life-cycle earnings profiles of two cohorts of workers. The model accounts for more than 55 percent of the observed flattening for high school-educated and for college-educated workers. Two channels generate the flattening in the model: selection (or higher college attainment) and a higher skill price for the more recent cohort. Absent selection, the model would have accounted for no ...

Institution, Major, and Firm-Specific Premia: Evidence from Administrative Data
We examine how a student?s major and the institution attended contribute to the labor market outcomes of young graduates. Administrative panel data that combine student transcripts with matched employer-employee records allow us to provide the first decomposition of premia into individual and firm-specific components. We find that both major and institutional premia are more strongly related to the firm-specific component of wages than the individual-specific component of wages. On average, a student?s major is a more important predictor of future wages than the selectivity of the institution ...

Causes and Consequences of Student-College Mismatch
Our objective is to understand the observed patterns of student-college sorting and earnings premia associated with college quality in the United States. Higher quality colleges have higher graduation rates and their graduates earn more. Yet, a large fraction of high scoring students enroll in two-year schools and low quality four-year schools – this “undermatch” phenomenon is more pronounced for low income students. To understand these patterns, we develop a model with heterogeneous students and colleges that differ in human capital production technology and financial costs. We ...

Student Loans Under the Risk of Youth Unemployment
While most college graduates eventually find jobs that match their qualifications, the possibility of long spells of unemployment and/or underemployment?combined with ensuing difficulties in repaying student loans?may limit and even dissuade productive investments in human capital. The author explores the optimal design of student loans when young college graduates can be unemployed and reaches three main conclusions. First, the optimal student loan program must incorporate an unemployment compensation mechanism as a key element, even if unemployment probabilities are endogenous and subject ...

The Changing Role of Family Income in College Selection and Beyond
Previous literature has established that the role of family income has grown substantially at predicting college entry decisions when comparing the 1979 and 1997 National Longitudinal Surveys of Youth (e.g., Belley and Lochner (2007)). In this article, I further examine the changing role of family income as a determinant of college quality choice, degree attainment, and post-schooling earnings. I document that the role of family income has remained important and relatively stable at explaining college quality choice, its importance increasing only for the choice of four- over two-year ...
