Since the end of court-mandated desegregation, many U.S. school districts have re-segregated along racial and economic lines. This paper examines the impacts of a 2018 policy in Charlotte, North Carolina which merged student populations from neighboring schools with differing socioeconomic statuses (SES). I find that the policy significantly reduced economic segregation at merged schools. However, it also led to a sharp decline in enrollment as families, primarily low-SES ones, opted out of attending these schools. I also find that students from predominantly low-SES neighborhoods (who would have likely attended the low-SES school in absence of the merging) experienced declines in standardized test performance and increased short-term out of school suspension rates, whereas those from predominantly high-SES neighborhoods showed modest gains in test scores and no change in suspension likelihood. Teacher retention increased at the merged schools. Finally, neighborhoods that were previously zoned to majority low-SES schools experienced an increase in house prices after the policy was implemented.
