Ji Yeon (Jean) Hong is an Associate Professor at the Division of Social Science, Hong Kong University of Science and Technology (HKUST). Her research interest is on the political economy of authoritarian regimes, with particular attention to East Asia such as China, Korea, Hong Kong, and Taiwan. She has various ongoing research projects related to authoritarian elites’ behavior, the legacies of authoritarianism, and contemporary state building in East Asia.

Charles Crabtree is a Senior Data Scientist at the Tokyo Foundation for Policy Research and a Visiting Scholar in the Department of Government at Dartmouth College, where he will be an Assistant Professor starting in fall 2020. His research focuses on fairness in politics, with applications to the study of discrimination, repression, human rights, policing, and immigration. Specifically, he examines under what circumstances political actors and institutions treat members of the public differently based on their political views or personal demographics, and how the public views this treatment. Understanding these phenomena is important as perceptions of fairness are fundamental to public evaluations of institutional legitimacy across regimes. Methodologically, he is interested in research design, experiments, and using computational tools to better understand the social world. He has published his research in the American Journal of Political Science, the British Journal of Political Science, the Journal of Politics, and Political Analysis, among other journals.

One strand of his research seeks to uncover the political logic of institutional development under authoritarian regimes. His book, Economic Growth and Endogenous Authoritarian Institutions in Post-Reform China (2019), develops a dynamic theory of authoritarian institutional change in the context of post-reform China. A second strand explores individual decision-making by utilizing advanced neuroscientific methods and data. A third strand builds on the theoretical insights developed from other parts of his research to address various issues regarding how China’s rise affects the regional dynamics in East Asia.
