|June 2020||The Long-Run Effects of School Racial Diversity on Political Identity|
with , : w27302
How do early-life experiences shape political identity? In this paper, we study how a shock to the social lives of youth affected their party affiliation in adulthood. Specifically, we examine the end of race-based busing in Charlotte-Mecklenburg schools (CMS), an event that led to large changes in school racial composition. Using linked administrative data, we compare party affiliation for students who had lived on opposite sides of newly drawn school boundaries. We find that a 10-percentage point increase in the share of minorities in a student's assigned school decreased their likelihood of registering as a Republican by 8.8 percent. Consistent with the contact hypothesis, this impact is entirely driven by white students (a 12 percent decrease). This effect size is roughly 16 percent of...
|November 2019||Moved to Vote: The Long-Run Effects of Neighborhoods on Political Participation|
with : w26515
How does one's childhood neighborhood shape political engagement later in life? We leverage a natural experiment that moved children out of disadvantaged neighborhoods to study effects on their voting behavior more than a decade later. Using linked administrative data, we find that children who were displaced by public housing demolitions and moved using housing vouchers are 12 percent (3.3 percentage points) more likely to vote in adulthood, relative to their non-displaced peers. We argue that this result is unlikely to be driven by changes in incarceration or in their parents' outcomes, but rather by improvements in education and labor market outcomes, and perhaps by socialization. These results suggest that, in addition to reducing economic inequality, housing assistance programs that i...
|Racial Disparities in Voting Wait Times: Evidence from Smartphone Data|
with , , : w26487
Equal access to voting is a core feature of democratic government. Using data from millions of smartphone users, we quantify a racial disparity in voting wait times across a nationwide sample of polling places during the 2016 U.S. presidential election. Relative to entirely-white neighborhoods, residents of entirely-black neighborhoods waited 29% longer to vote and were 74% more likely to spend more than 30 minutes at their polling place. This disparity holds when comparing predominantly white and black polling places within the same states and counties, and survives numerous robustness and placebo tests. We shed light on the mechanism for these results and discuss how geospatial data can be an effective tool to both measure and monitor these disparities going forward.
|June 2019||Inaccurate Statistical Discrimination: An Identification Problem|
with , , : w25935
Discrimination has been widely studied in the social sciences. Economists often categorize the source of discrimination as either taste-based or statistical—a valuable distinction for policy design and welfare analysis. In this paper, we highlight that in many situations economic agents may have inaccurate beliefs, and demonstrate that the possibility of inaccurate statistical discrimination generates an identification problem for attempts to isolate the source of differential treatment. We introduce isodiscrimination curves—which represent the set of preferences and beliefs that generate the same level of discrimination—to formally outline the identification problem: when not accounted for, inaccurate statistical discrimination can be mistaken for taste-based discrimination, accura...
