This paper studies the impacts of state appropriations on staffing and salaries at public higher education institutions in the United States using employment and revenue data from the Integrated Postsecondary Education Data System, along with an instrumental variables strategy borrowed from Deming and Walters (2018) and Chakrabarti, Gorton, and Lovenheim (2020). The instrument sidesteps the potential endogeneity of state appropriations for a given institution in a given year by interacting an institution’s historical reliance on state appropriations with total state appropriations for all higher education institutions in a given year. The results suggest that higher state appropriations are associated with an increase in tenure-track assistant professors at four-year institutions. They are also associated with an increase in part-time instructional staff at both four-year and two-year institutions. However, they are not associated with a change in the number of tenured faculty. Appropriations are also positively related to salaries for a variety of employee groups, although notably not for instructional staff who are instructors, lecturers, or without an academic rank. Overall, the results show that public higher education institutions use state appropriations in a variety of ways, but I do not find evidence that they replace contingent faculty with tenured or tenure-track faculty when appropriations rise.

Prior research suggests that statewide affirmative action bans reduce minority enrollment at selective colleges while leaving overall minority college enrollment unchanged. However, the effect of these bans on across-college racial segregation has not yet been estimated. This effect is theoretically ambiguous due to a U-shaped relationship across colleges between minority enrollment and college selectivity. This paper uses variation in the timing of affirmative action bans across states to estimate their effects on racial segregation as measured by standard exposure and dissimilarity indexes, finding that affirmative action bans have increased segregation across colleges in some cases but reduced it in others. In particular, early affirmative action bans in states with highly selective public universities appear to be associated with less segregation, whereas more recent affirmative action bans appear to be associated with more segregation.

A number of US states have enacted bans on tobacco use by students, staff, and visitors anywhere on the grounds of public elementary and secondary schools statewide. These laws are intended to reduce tobacco use, reduce exposure to secondhand smoke, reinforce anti-tobacco curricula taught in schools, and prevent children from viewing their teachers and fellow students using tobacco products. We examine the impact that the laws have on the smoking behavior of students, teachers, and other school staff by estimating difference-in-differences models that exploit the time variation in adoption of the laws across states. We generally find that these laws do not impact smoking behavior, although we do find some evidence suggesting a possible effect on nonteaching school staff.

Teacher quality is a pressing public policy concern, yet there is little evidence on what types of teachers schools actually prefer to hire. This paper reports the results of an experiment that involved sending schools fictitious resumes with randomly-chosen characteristics in an attempt to determine what characteristics schools value when hiring new teachers. The results of the study suggest that an applicant’s academic background has little impact on the likelihood of success at private and charter schools, although public schools respond more favorably to candidates from more selective colleges. Additionally, private schools demonstrate a slight preference for female candidates, and all three sectors demonstrate a preference for in-state candidates.

This descriptive paper documents how segregation between blacks and whites across colleges in the United States has evolved since the 1960s. It also explores potential channels through which changes are occurring, and it uses recent data to study the issue of segregation within colleges. The main findings are as follows: (1) White exposure to blacks has been rising since the 1960s, whereas black exposure to whites increased sharply in the late 1960s and early 1970s and has fluctuated since then. Meanwhile, black-white dissimilarity and the Theil index fell sharply in the late 1960s and early 1970s and have fallen more gradually since. (2) There has been regional convergence, although colleges in the South remain more segregated than those in any other region when measured by dissimilarity, by the Theil index, or by black exposure to whites. (3) A major channel for the decline in segregation is the declining share of blacks attending historically black colleges and universities. (4) Although there is segregation within universities, most segregation across major university cells occurs across universities.

Research suggests that the COVID-19 pandemic may have lasting impacts on education in the United States.

This Commentary reviews evidence on three areas of concern related to the COVID-19 pandemic and education in the United States for which research currently exists. First, the evidence suggests that the spread of the COVID-19 virus at K–12 schools has been low, although it may have spread through colleges at a higher rate. Second, while anecdotal evidence suggests that school closures have reduced labor force participation, the research evidence thus far does not find much support for this situation. Third, the limited research evidence does, however, suggest the COVID-19 pandemic is negatively affecting students’ academic performance.

This Economic Commentary studies whether statewide bans on affirmative action in admission to public universities cause students to move to a new state to attend college. Regression results using data from the decennial census and the American Community Survey provide little evidence that affirmative action bans result in migration across state lines to attend college. In addition to being of direct interest, these results provide a check on earlier research that treats different states roughly as separate higher education markets.

This Economic Commentary studies the behavior of colleges when they are asked to list a set of comparison group colleges in annual data reporting for the US Department of Education but are given little direction on how to do so. I find that, relative to themselves, colleges tend to list for comparison colleges that are more selective, are larger, and have better resources. One possible interpretation of these findings is that colleges overestimate where they stand relative to others, although an alternative interpretation is that colleges have accurate views but list comparison institutions based on aspirations.

This Economic Commentary documents the large dispersion in the value of college endowments across institutions and also shows how endowment values have changed over time. It also provides information on the number of institutions that may be affected by the new federal “endowment tax” and how that number may fluctuate over time.

This Economic Commentary studies trends in inflated-adjusted revenues per student at US colleges and universities in broad revenue categories between 1987 and 2013. The findings show that, as is widely perceived, tuition revenue has risen over time at both public and private institutions. In recent years, tuition revenue at public institutions has been nearly as large a source of revenue as state and local government funding has been. Revenue from state and local governments has fluctuated at public institutions but has generally fallen over time, whereas funding from the federal government has risen. Investment returns are a large and highly variable source of revenue, especially for private institutions.

This Economic Commentary studies trends in spending by US colleges and universities in broad expenditure categories between 1987 and 2013. The results reveal that spending per student has risen in most major spending categories. This is true for both public institutions and private institutions. However, spending has risen more dramatically in some categories than others. For example, research is one category that has witnessed among the highest spending growth, and in percentage terms, there has also been a large increase in student services spending.

This Economic Commentary studies employment at colleges and universities in the United States between 1987 and 2013. Some of the results from this analysis are in line with conventional wisdom. For example, I document that a declining proportion of faculty are full-time employees. On the other hand, some of the results are counter to popular belief. For example, I find that the share of college employees who are executives, administrators, or managers has not changed appreciably over time.

While affirmative actions bans tend to lead minority students to attend slightly less selective colleges in general, in some cases this means they enroll in places that had low minority representation before, thus evening out minority representation across schools overall.

There are large differences in the average earnings of people who choose different college majors. Could differences in major choice explain some of the income gap between blacks and Hispanics relative to whites and Asians?
