Assoc Prof Yohanes Eko Riyanto

Biography
Associate Professor Yohanes Eko Riyanto joined the Division of Economics, School of Humanities and Social Sciences NTU in July 2009. Previously he was with the Department of Economics, Faculty of Arts and Social Sciences NUS. Prior to that, he was a post-doctoral fellow at the Department of Economics of the University of Groningen in the Netherlands. He obtained his Ph.D. in Economics from the Catholic University of Louvain/ Katholieke Universiteit Leuven (Leuven-Belgium).

His research focuses on Experimental and Behavioral Economics topics. He utilizes controlled laboratory experiments to investigate how individuals make a host of economic decisions and how these decisions are influenced by their preferences and beliefs, their environment (market and non-market institutions surrounding them), and their strategic interactions with other individuals. He incorporates insights from microeconomics, game theory, behavioral sciences to formulate testable experimental hypothesis.

He has published his research in leading internationally refereed journals such as Journal of Finance, International Economic Review, Review of Economics and Statistics, Experimental Economics, and Journal of Economic Behavior and Organization (JEBO). He is an Associate Editor of JEBO. He actively disseminated his research works in prestigious international conferences. His work has also been covered by the popular press such as the Economist, the Wall Street Journal, Financial Times, the New Statesman, and others.

He teaches Behavioral Economics and Microeconomics courses at both undergraduate and graduate level at Nanyang Technological University. Further information about him can be accessed from http://www.expernomics.com/yer.
Research Interests
Currently, he is working on several research thrusts. They are the followings. The first is the experimental asset market and finance. Within this research thrust, he studies various topics ranging from the insider trading and its regulatory framework, the interplay between social networks, information acquisition and aggregation, and traders behaviors, the link between consumption smoothing and heterogeneous traders and its impact on asset prices, and many others.

The second is the design of organ transplant allocation from donors to recipients. Specifically, he studies how the donor allocation priority should be designed to incentivize individuals to enroll in the organ donation program; while taking into consideration the issue of blood compatibility between donated organs and the transplant recipients and the incentive scheme in the form of transferrable donation vouchers.

The third is social preferences in general; ranging from, among others, the mechanisms to enhance cooperation and coordination in social dilemma settings, cooperation and coordination in social networks where individuals belonging to social networks can endogenously decide with whom they want to form links with before engaging in the prisoner's dilemma or coordination game with their link partners, the incentive of buyers and sellers to engage in social responsibile acts in the market place, and the role of social identity in intra- and inter-group interaction..
