Community College Bachelor’s Degrees: How CCB Graduates’ Earnings Compare to AAs and BAs (with Riley Acton ⓡ, Camila Morales ⓡ, Kalena Cortes ⓡ, and Lois Miller ⓡ). NBER Working Paper No. 34684.
- - We provide the first descriptive analysis of the economic value of Community College Baccalaureate (CCB) degrees by examining graduates’ early-career earnings, the costs of completing these programs, and the alignment between field of study and subsequent employment. Using administrative data and controlling for institution and field, we find that CCB graduates earn $4,000 to $9,000 more annually than Associate’s (AA) degree holders one year after graduation but experience average earnings penalties of roughly $2,000 relative to traditional Bachelor’s (BA) recipients. These averages mask substantial heterogeneity: penalties are largest in Computer and Information Technology and Engineering Technology, whereas CCB graduates in Nursing, other Healthcare fields, Business, and Criminal Justice exhibit minimal or no penalties. To contextualize these returns, we analyze tuition and fee structures across CCB-granting institutions and identify two dominant pricing models—constant and escalating. Total CCB program costs fall between those of AA and BA degrees, with escalating structures increasing upper-division prices by about 40 percent. Finally, we examine field-to-industry match patterns and find that CCB graduates in fields with well-defined occupational pathways, such as Health Professions and Education, are highly concentrated in aligned industries, while graduates in more diffuse fields, such as Computer Science, are more broadly dispersed.

Universal Pre-K as Economic Stimulus: Evidence from Nine States and Large Cities in the U.S. (with Kirabo Jackson and Jacob Bastian). NBER Working Paper No. 33767.
- - While Universal Pre-Kindergarten (UPK) is often proposed as an economic stimulus, its market effects remain uncertain. We analyze UPK programs implemented across nine states and cities from 1995 to 2020, leveraging their staggered adoption for identification. UPK increased Pre-K enrollment and led to a 1.2% rise in labor force participation, a 1.5% increase in employment, and a 1.6% growth in hours worked, resulting in higher aggregate earnings. Employment effects were strongest for mothers but extended to other groups, primarily women. Impacts varied, with the largest effects observed in areas with high public Pre-K enrollment. Notably, each dollar spent on UPK generated between 3 to over 20 dollars in aggregate earnings – enough that tax revenues might fully cover costs.
Theoretical foundations of the minimum wage and post-secondary investment
- - Building on canonical models of human capital investment, this paper explores the potential of the minimum wage to impact college enrollment decisions by shifting both the wage premium and the opportunity cost associated with post-secondary investment. Whereas existing literature presents conflicting evidence on enrollment responses across two- and four-year institutions, I present a unifying framework with which to make sense of these effects. Using national post-secondary enrollment data from IPEDS and wage data from the CPS, I show that the extent to which these parameters are shifted by a changing minimum wage is a function of prevailing wage distributions in the year before a minimum wage change occurs and, specifically, who is bound by the new minimum wage. Guided by my theoretical framework, I use variation in state-level minimum wage changes to size the determinants of enrollment responses to individual changes across years and states. I show that states in which higher shares of high school graduates are bound by the minimum wage are those most likely to experience large enrollment declines at community colleges in response to an increasing minimum wage. Finally, I use my framework to consolidate conflicting estimates from the existing literature.
