Though MOOCs and online technology have generated excitement about their potential to increase access to education, most existing research has focused on comparisons of student performance across online and in-person formats. We provide the first evidence on the impact of online education on the amount of education pursued. Georgia Tech's Online M.S. in Computer Science is the first model combining the inexpensive nature of MOOCs with a degree program from a highly-ranked institution, a price-quality pairing that has not been seen before. A regression discontinuity design around an admissions threshold shows that access to this low cost, high quality option substantially increases the amount of formal education pursued, with demand driven largely by mid-career Americans for whom in-person options are not appealing. Our estimates suggest that, by satisfying previously unmet demand for mid-career training, this single program will boost annual production of American computer science master’s degrees by eight percent.
