Recently, there has been a move towards K-8 schools as opposed to separate elementary and middle schools, especially among urban districts. In this paper, we examine the effect of enrollment in separate elementary and middle schools relative to enrollment in a K-8 school using longitudinal data from an anonymous district in the United States. The choice to enroll in a K-8 or separate elementary and middle schools is potentially endogenous. While previous research has taken steps to address the possible endogeneity when estimating the effects for separate middle schools, previous research has not addressed the possible endogeneity when examining the effect at the elementary level. Without generating an unbiased estimate during the elementary grades, we cannot fully understand the impact of policies that have shifted the grade arrangement of separate elementary and middle schools to K-8 schools. In this paper, we employ a research design that leverages the fact that the anonymous district closed several schools and rezoned their students to other schools with new boundaries. We compare students on the side of the new boundaries who are assigned to a separate middle or elementary school to students on the other side of the new boundaries who are assigned to a K-8 school. When taking into the consideration the effect at the elementary level, our results are much less supportive of a K-8 policy than previous research.

Since their inception in 1992, the number of charter schools has grown to more than 6,000 in 40 states, serving more than 2 million students. Various studies have examined charter schools' impacts on test scores, and a few have begun to examine longer-term outcomes including graduation and college attendance. This paper is the first to estimate charter schools' effects on student earnings, alongside effects on educational attainment. Using data from Chicago and Florida, we find evidence that charter high schools may have substantial positive effects on persistence in college as well as high-school graduation and college entry. In Florida, where we can link students to workforce data in adulthood, we also find evidence that charter high schools produce large positive effects on subsequent earnings.
