This doctoral dissertation consists of three independent studies of higher education. The first study uses a natural experiment at a selective university in Central Asia and a difference-in-differences strategy to estimate the causal effect of switching to English-only instruction on students’ college outcomes. The findings suggest that the introduction of English-only instruction led to a decrease of GPAs and probability of graduation and an increase in the number of failed course credits. Although negative, the effects were short-lived. The second study examines whether the chaperone effect, whereby authors who have first published as non-leading authors have better chances to publish later as leading authors, is present in academic publishing in economics, education, political science, psychology, and sociology by analyzing bibliometric data of more than 600,000 articles. The analyses suggest a limited presence of the chaperone effect in social science publications. The third study was a randomized field experiment testing the implementation of the AdmitHub artificially intelligent text-message based virtual assistant to reduce summer melt and improve first-year college enrollment at East Carolina University (ECU) and Lenoir Community College (LCC). At ECU, the positive effects of the virtual assistant were concentrated among first-generation students. For LCC, where the randomized experiment could not be robustly implemented due to having access to cell phone information for only a limited number of students, a qualitative analysis of readiness for chatbot implementation is presented.
