Long's research focuses on the economics of education with particular attention on the transition from high school to higher education and beyond. She has examined factors that influence student enrollment decisions, choice, and persistence in post-secondary education. Much of her work investigates the impact of education policies and programs, and several projects apply insights from behavioral economics to education. Long has conducted several large, randomized controlled trials to establish the causal effects of interventions designed to better support students. Working with co-authors, she conducted a major study on the impact of information and assistance on completing financial aid forms. The study contributed to quantitative evidence on the detrimental effects complex processes can have on educational attainment, and it has been cited in efforts to simplify the federal financial aid application. Long followed this work with studies on the effectiveness of interventions that focus on helping families save for higher education and students persist in college. She has also written about how the government and institutions could help students to make better educational decisions by providing clear, easy-to-access information. Long has also used of state administrative data to explore long-standing questions in higher education, and she produced some of the earliest large-scale studies on the causal effects of post-secondary remediation, different types of instructors, and the . She was selected to be a Fellow of the and is also a past recipient of the National Academy of Education/Spencer Postdoctoral Fellowship. The awarded Long the Robert P. Huff Golden Quill Award for excellence in research and published works on student financial assistance.
