Course description and aims

Professor's visit to Tokyo has been postponed and not determined. For the time being, lectures will be canceled.
This course aims to help students to understand basic principles of network economics and encourage them to apply the principles to real economic and business issues. This course is interdisciplinary across different fields. We first address ‘Conventional Network Economics’ including network externalities, increasing returns principle, and then several practical issues related to information good, technology competition, standardization, spatial pattern, and so on. Secondly, students study a basic ‘Network Science’ and related issues such as network structure, network topology, strong tie and weak tie, homophily, and so on. Thirdly, students explore “Complexity’ in natural science and related issues that are handled in physics, biology, neural network. Finally, if time is allowed, we discuss some contemporary issues; Discrepancy and Instability, System Risk. Innovation System, Information Cascades, etc. Through this course students will be able to develop a basic research capability to address research questions, hypotheses, methodologies, and verification, interpretation in Network Economics.

Student learning outcomes

When students complete successfully this course they will be able to
∙ understand the principles(theories) of network economics
∙ understand how standard economics and network economics are
different
∙ know how to apply network economic theories to practical issues
∙ learn the concepts and methodologies of network topology: graph
theory, social network analysis
∙ know how to do interdisciplinary approaches, specially economics,
physics, network science, complexity science, and so on
∙ address how to develop research question, hypothesis, and model
∙ know how to test the hypothesis, interpret the results, and derive the
implication

Keywords

network economics, network externalities, power-law distribution, critical mass, increasing returns, path-dependence, positive feedback, multiple equilibria, network science, network topology, random network, scale-free network, small-world network, strong tie, weak tie, structural hole, homophily, complexity, phase transition, self-organization, synchronization, discrepancy, instability, system risk. innovation system, information cascades, herding behavior

Competencies that will be developed

✔ Specialist skills ✔ Intercultural skills Communication skills ✔ Critical thinking skills ✔ Practical and/or problem-solving skills

Class flow

Intensive lectures will be given depending on the schedule.This lecture will be held for two consecutive frames.13:20～16:40
This course will be held for 7 classes within first Q, in 200 min. each. This course adopts interdisciplinary approach and basically discuss the analogy between social science and natural science through the course. So we conduct the following steps; Network Economics → Network Science → Complexity Science

In each sector we try to cross theory and practice and want students to build the capability to apply network economic theories to practical issues

Finally we will have chance to address how to develop research question, hypotheses, and verify them by individual or group presentation
