Digitization and Divergence: Online School Ratings and Segregation in America. Read article. Abstract: We analyze whether widespread online access to school quality information affected economic and social segregation in America. We leverage the staged roll-out of GreatSchools.org school ratings across America from 2006-2015 to answer this question. Across a range of outcomes and specifications, we find that the mass availability of school ratings has accelerated divergence in housing values, income distributions, education levels, as well as the racial and ethnic composition across communities. Affluent and more educated families were better positioned to leverage this new information to capture educational opportunities in communities with the best schools. An unintended consequence of better information was less, rather than more, equity in education.
