Educator labor markets

This study investigates whether a principal’s likelihood of hiring a teacher of color is sensitive to the racial composition of students in the school. We used an administrative dataset from Texas including 59,157 principal observations and 662,997 teacher observations spanning 2000 to 2017 in order to consider whether or not the disappearing diversity from a majority white school is a factor in principals’ decisions to hire teachers of color. We examined the hiring patterns of principals within schools where 50% of the students were white and compared the probability that a nonwhite teacher would be hired as the homogeneity of the student body increased (that is, as increasing proportions of the student body were white). We found that white principals were less likely to hire teachers of color as the proportion of white students approached 100%. This study provides initial evidence that teacher hires are not only sensitive to the principal’s race but also to the racial composition of the student body. Specifically, as the diversity of the student body disappears, so too does the principal’s likelihood of hiring a teacher of color.

We examine the causal influence of educators elected to the school board on local education production. The key empirical challenge is that school board composition is endogenously determined through the electoral process. To overcome this, we develop a novel research design that leverages California's randomized assignment of the order that candidate names appear on election ballots. We find that an additional educator elected to the school board reduces charter schooling and increases teacher salaries in the school district relative to other board members. We interpret these findings as consistent with educator board members shifting bargaining in favor of teachers' unions.

We document a largely unrecognized pathway through which schools promote human capital development – by fostering informal mentoring relationships between students and school personnel. Using longitudinal data from a large, nationally representative sample of adolescents, we explore the frequency, nature, and consequences of school-based natural mentorships. Estimates across a range of fixed effect (FE) specifications, including student FE and twins FE models, consistently show that students with school-based mentors achieve greater academic success and higher levels of post-secondary attainment. These apparent benefits are evident for students across a wide range of backgrounds but are largest for students of lower socioeconomic status.

COVID-19 shuttered schools across the United States, upending traditional approaches to education. We examine teachers’ experiences during emergency remote teaching in the spring of 2020 using responses to a working conditions survey from a sample of 7,841 teachers across 206 schools and 9 states. Teachers reported a range of challenges related to engaging students in remote learning and balancing their professional and personal responsibilities. Teachers in high-poverty and majority Black schools perceived these challenges to be the most severe, suggesting the pandemic further increased existing educational inequities. Using data from both pre-post and retrospective surveys, we find that the pandemic and pivot to emergency remote teaching resulted in a sudden, large drop in teachers’ sense of success. We also demonstrate how supportive working conditions in schools played a critical role in helping teachers to sustain their sense of success. Teachers were less likely to experience declines in their sense of success when they worked in schools with strong communication, targeted training, meaningful collaboration, fair expectations, and authentic recognition during the pandemic.

This case study offers an organizational perspective on the ways in which a collective bargaining agreement shaped the administrative functioning of schools within an urban district. The data demonstrate how rational choice assumptions failed to account for the everyday site interactions between principals and teachers. Using complexity theory as an analytic tool, the authors consider the interference of external pressures on a system defined by internal interdependence. Reforms that address the complexity of workplace conditions in K-12 contexts are offered.

We show that fade out biases value-added estimates at the teacher-level. To do so, we use administrative data from North Carolina and show that teachers' value-added depend on the quality of the teacher that preceded them. Value-added estimators that control for fade out feature no such teacher-level bias. Under a benchmark policy that releases teachers in the bottom five percent of the value-added distribution, fifteen percent of teachers released using traditional techniques are not released once fade out is accounted for. Our results highlight the importance of incorporating dynamic features of education production into the estimation of teacher quality.

Test-based accountability pressures have been shown to result in transferring less effective teachers into untested early grades and more effective teachers to tested grades. In this paper, we evaluate whether a state initiative to turnaround its lowest performing schools reproduced a similar pattern of assigning teachers and unintended, negative effects on the outcomes of younger students in untested grades. Using a sharp regression discontinuity design, we find consistent evidence of increased chronic absenteeism and grade retention in the first year. Also, the findings suggest negative effects on early literacy and reading comprehension in the first year of the reform that rebounded somewhat in the second year. Schools labeled low performing reassigned low effectiveness teachers from tested grades into untested early grades, though these assignment practices were no more prevalent in reform than control schools. Our results suggest that accountability-driven school reform can yield negative consequences for younger students that may undermine the success and sustainability of school turnaround efforts.

Teachers are among the most important school-provided determinants of student success. Effective teachers improve students’ test scores as well as their attendance, behavior, and earnings as adults. However, students do not enjoy equal access to effective teachers. This article reviews some of the key challenges associated with teacher policy confronted by school leaders and education policymakers, and how the tools of applied economics can help address those challenges. The first challenge is that identifying effective teachers is difficult. Economists use value-added models to estimate teacher effectiveness, which works well in certain circumstances, but should be just one piece of a multi-measure strategy for identifying effective teachers. We also discuss how different policies, incentives, school characteristics, and professional-development interventions can increase teacher effectiveness; this is important, as schools face the daunting challenge of hiring effective teachers, helping teachers to improve, and removing ineffective teachers from the classroom. Finally, we discuss the supply and mobility of teachers, including the consequences of teacher absenteeism, the distribution of initial teaching placements, and the characteristics and preferences of those who enter the profession.

Using data with detailed instructor employment information from a state college system, this study examines disciplinary variations in the characteristics and effects of non-tenure-track faculty hired through temporary and long-term employment. We identify substantial differences in the demographic and employment characteristics between the two types of non-tenure-line faculty, where the differences are most pronounced in STEM fields at four-year colleges. Using an instrumental variables strategy to address student sorting, our analyses indicate that taking introductory courses with temporary adjuncts reduces subsequent interest, and the effects are particularly large in STEM fields at four-year colleges. Long-term non-tenure faculty are generally comparable to tenure-track faculty in student subsequent interest, but tenure-track faculty are associated with better subsequent performance in a handful of fields.

Numerous studies have considered the important role of cognition in estimating the returns to schooling. How cognitive abilities affect schooling may have important policy implications, especially in developing countries during periods of increasing educational attainment. Using two longitudinal labor surveys that collect direct proxy measures of cognitive skills, we study the importance of specific cognitive domains for the returns to schooling in two samples. We instrument for schooling levels and we find that each additional year of schooling leads to an increase in earnings by approximately 18-20 percent. The estimated effect sizes—based on the two-stage least squares estimates—are above the corresponding ordinary least squares estimates. Furthermore, we estimate and demonstrate the importance of specific cognitive domains in the classical Mincer equation. We find that executive functioning skills (i.e., memory and orientation) are important drivers of earnings in the rural sample, whereas higher-order cognitive skills (i.e., numeracy) are more important for determining earnings in the urban sample. Although numeracy is tested in both samples, it is only a statistically significant predictor of earnings in the urban sample. (JEL I21, F63, F66, N37)
