Published and Forthcoming"Missed Exams and Lost Opportunities: Who Could Gain from Expanded College Admission Testing?," with Sarah Turner (UVA), AERA Open, 2019, Volume 5, Issue 2, pp 1-20. https://doi.org/10.1177%2F2332858419855030
Abstract: When students with the capacity to succeed in a four-year college do not take a college admission test, this represents a potential loss of opportunity for students and colleges alike. However, the costs of testing—both pecuniary and non-pecuniary—may exceed the benefits for students who lack the interest in or qualifications for college attendance. In states like Virginia, access to admission tests varies markedly with district and family circumstances. We estimate that universal testing in Virginia could increase the number of high school graduates with test scores competitive for admission at broad-access universities in the state by as much as 40%—and at the most selective institutions, nearly 20%—with larger increases for low-income students. Alternative policies that encourage testing among students with high demonstrated academic performance could realize nearly these increases without generating testing costs for students who are unlikely to attend a four-year college.
"Network Structure and Consolidation in the U.S. Airline Industry, 1990-2015," with Federico Ciliberto (UVA) and Jonathan W. Williams (UNC-Chapel Hill), The Review of Industrial Organization,, Volume 54, Issue 1, pp 3–36. https://doi.org/10.1007/s11151-018-9635-y
Abstract: We study the effect of consolidation on airline network connectivity using three measures of centrality from graph theory: Degree; Closeness; and Betweenness. Changes in these measures from 1990 to 2015 imply: (i) the average airport services a greater proportion of possible routes; (ii) the average origin airport is fewer stops away from any given destination; and (iii) the average hub is less often along the shortest route between two other airports. Yet, we ﬁnd the trend toward greater connectivity in the national network structure is largely unaffected by consolidation—in the form of mergers and codeshare agreements—during this period.
"Transitioning from High School to College: Differences across Virginia," with Jessie Romero (Richmond Fed) and Sarah Turner (UVA). Federal Reserve Bank of Richmond Economic Brief, 2017, 17-12. https://www.richmondfed.org/publications/research/economic_brief/2017/eb_17-12
Abstract: In Virginia, there are substantial differences across school districts in college enrollment and, conditional on college enrollment, attendance at high resource colleges and universities. School districts in low-income and relatively rural areas tend to demonstrate the weakest outcomes, but income and geography do not fully account for the observed differences. Whether limited enrollment at a broad range of colleges arises from gaps in academic preparation, difficulty in navigating the application process, or individual preference matters greatly for public policy.
Working Papers"Pricing Public Higher Education: Responses to Appropriations Changes in a Market Context", with Sarah Turner (UVA)
Abstract: As public universities have experienced an overall retrenchment in support from state governments in recent decades, tuition levels have also increased markedly. This analysis examines the question of how the posted tuition and the net price faced by students from different economic circumstances adjusts to changes in public subsidies or state appropriations. Our interest is in modeling the link between changes in state appropriations and prices for different types of students across the distribution of public colleges and universities. Within states, public colleges and universities differ substantially in how they adjust tuition levels and associated net prices to changes in appropriations. Public research universities, which are generally the most selective and most resource-intensive within a state, typically demonstrate greater changes in response to appropriations declines than their broad access counterparts. In turn, these public research universities tend to distribute tuition increases progressively across income bins with net price for low-income students increasing less than dollar-for-dollar with posted tuition increases. In contrast, net price changes are closer to dollar-for-dollar across all income groups at broad access institutions. Distinguishing further among state markets and institutions, universities in states with a relatively high representation of high-income families (who are likely to be price inelastic) and those with fewer private sector competitors are the most likely to move to high-tuition, high-need pricing strategies.
