Soojong Kim

Soojong Kim is a postdoctoral fellow, jointly affiliated with the Program on Democracy and the Internet (PDI) and the Digital Civil Society Lab (DCSL). He received his PhD at the Annenberg School for Communication, University of Pennsylvania. His research centers around social media, misinformation, and computational social science. As a former computer scientist and engineer, he is also interested in applying and developing innovative research methods, including web-based experiments, computational modeling, network analysis, and natural language processing.

He is recently focusing on three research projects. (1) Real-time Misinformation Monitoring: Evaluating the impacts of real-world misinformation messages in real-time and reducing their adverse socio-psychological consequences. (2) Virtual Social Media: Discovering and examining factors that influence behavior and perception of social media users based on interactive multi-agent network experiments. (3) Map of Misinformation: Investigating the structure of disinformation messages and the landscape of the fake news ecosystem and designing effective misinformation suppression/prevention strategies.

Dr. Kim worked at Samsung Electronics as a computer scientist for several years after earning his B.S. and M.S. degrees in Electrical Engineering and Computer Science from Seoul National University, South Korea. He also holds his Master's degree in sociology. He is a recipient of the ICA Best Paper Award, Wharton Russell Ackoff Fellowship, Waterhouse Family Institute Research Grant Award, Annenberg Doctoral Research Fellowship, and MisinfoCon Research Grant.

Josh A. Goldstein is a past postdoctoral scholar at the Stanford Internet Observatory. He received his PhD in International Relations from the University of Oxford, where he studied as a Clarendon Scholar. At the Stanford Internet Observatory, Dr. Goldstein investigated covert influence operations on social media platforms, studied the effects of foreign interference on democratic societies, and explored how emerging technologies will impact the future of propaganda campaigns. He has given briefings to the Department of Defense, the State Department, and senior technology journalists based on this work, and published in outlets including Brookings, Lawfare, and Foreign Policy.

Prior to joining SIO, Dr. Goldstein received an MPhil in International Relations at Oxford with distinction and a BA in Government from Harvard College, summa cum laude. He also assisted with research and writing related to international security at the Belfer Center, Brookings Institution, House Foreign Affairs Committee, and Department of Defense.

Paragraphs

One of the most puzzling findings in asset pricing is that expected returns dominate variation in the dividend-to-price ratio, leaving little room for dividend growth rates. Even more puzzling is that this dominance only emerged after 1945. We develop a present value model to argue that a general increase in equity duration can explain these findings. As cash flows to investors accrue further into the future, shocks to highly persistent expected returns become relatively more important than shocks to growth rates. We provide supportive empirical evidence from dividend strips, the time-series, and the cross-section of stocks.

Paragraphs

We develop a model of financial crises with both a financial amplification mechanism, via frictional intermediation, and a role for sentiment, via time-varying beliefs about an illiquidity state. We confront the model with data on credit spreads, equity prices, credit, and output across the financial crisis cycle. In particular, we ask the model to match data on the frothy pre-crisis behavior of asset markets and credit, the sharp transition to a crisis where asset values fall, disintermediation occurs and output falls, and the post-crisis period characterized by a slow recovery in output. We find that a pure amplification mechanism quantitatively matches the crisis and aftermath period but fails to match the pre-crisis evidence. Mixing sentiment and amplification allows the model to additionally match the pre-crisis evidence. We consider two versions of sentiment, a Bayesian belief updating process and one that overweighs recent observations. We find that both models match the crisis patterns qualitatively, generating froth pre-crisis, non-linear behavior in the crisis, and slow recovery. The non-Bayesian model improves quantitatively on the Bayesian model in matching the extent of the pre-crisis froth.
