Andrew Ching, PhD (University of Minnesota), is a Professor at the Carey Business School at Johns Hopkins University, where he serves as Area Chair for Marketing and holds joint appointments in the Department of Economics and the Bloomberg School of Public Health. In addition, he is a core faculty member at the Hopkins Business of Health Initiative, a faculty affiliate at the Technology and Society Initiative, a faculty associate at the Canadian Centre for Health Economics, and a member of the Academy of Public Health. From 2020 to 2026, he co-founded and served as the Research Director of the Digital Business Development Initiative. Prior to joining Johns Hopkins, he held faculty appointments at the University of Toronto and The Ohio State University. He has also held visiting professor appointments at UCLA, Cornell University, the University of Wisconsin–Madison, the National University of Singapore, and HKUST, as well as visiting scholar appointments at Harvard University, Peking University, the Federal Reserve Bank of Boston, and the Federal Reserve Bank of Kansas City. Furthermore, he has served as a Distinguished Visiting Professor at the Chinese University of Hong Kong, and as a Distinguished Visiting Scholar at the University of Macau and Peking University HSBC Business School.
He currently serves on the editorial boards of the International Journal of Research in Marketing, Review of Marketing Science, and the International Journal of Pharmaceutical and Healthcare Marketing, and as a topic editor for the Journal of Risk and Financial Management. He also serves on several panels for the Hong Kong Research Grants Council, including the Business Studies Panel. Previously, he served as an Associate Editor for Management Science (2014–2022) and on the editorial boards of Marketing Science (2014–2021) and the Journal of Marketing Research (2016–2026).
His research focuses on developing new empirical structural models and estimation methods to understand the forward-looking, strategic, learning, state-dependent, and boundedly rational behavior of consumers and firms under complex environments (including rational inattention and exploration–exploitation problems). He has applied these techniques to study the demand for prescription drugs and nursing homes, new technology adoption decisions, choice of payment methods, information spillovers, late-mover advantages, firm adaptation to concept drift, video game demand, consumer stockpiling, online support groups, and integrated marketing communications. His latest research investigates how information friction affects critical decisions, such as consumer search behavior in complex settings and the mechanisms through which AI systems may amplify misinformation.
He is the recipient of the Young Economist Award from the European Economic Association, a Finalist for the John D.C. Little Award, an Honorable Mention for the Dick Wittink Prize, and multiple major research grants from the Social Sciences and Humanities Research Council of Canada (SSHRC). In addition, he has served as a keynote and distinguished speaker at numerous international conferences and universities. His PhD students have received the MSI Clayton Dissertation Proposal Award and the ISMS Dissertation Proposal Award.

He has also consulted for pharmaceutical, tobacco, and healthcare product companies, serving as an expert witness in litigation and arbitration matters.
