Industrial organization is a branch of microeconomics that studies markets of imperfect competition. When the number of competitors is small and competition is imperfect, each individual firm faces situations of strategic interaction among the market participants (consumers, competitors, or suppliers). Using game theoretic tools, this course studies various market structures and the competitive and cooperative strategies used by profit-maximizing firms as well as their implications for market outcomes and regulation policies. Topics include Markets and strategies, Static oligopoly competition, Dynamic oligopoly competition, Source of market power, Price discrimination, Impact of asymmetric information, Cartels and collusion, Horizontal mergers, and Vertically-related markets.

Prerequisite: Game Theory

This course covers diplomacy and international negotiations in the context of international relations. 

The first section focuses on the history and importance of diplomacy and the role of diplomats in resolving conflicts among countries. The Westphalia system (1648), the Congress of Vienna (1815), the Versailles Treaty (1919), the League of Nations and the United Nations will be also explained as a part of multilateral diplomacy.  

The second section covers the concept of diplomacy, theories related to diplomacy, and types and methods of negotiations. Students will examine case studies of past and current international negotiations such as in the Cuban Missile Crisis, Iran and North Korean nuclear issues.  

Finally, students will create presentations and a term paper on any case of international negotiation. 

This course explores key concepts and principles of the techniques used to give textiles various colors. Dyeing is the process of imparting color to textiles using dyes or pigments, and it is the most efficient method for enhancing the marketability and aesthetic appeal of clothing products. Students will study the fundamentals of fiber science to understand the structure and characteristics of textiles and learn about the theory of dye chemistry to comprehend the properties and interactions of diverse chemical substances used in dyeing. Additionally, the course examines color theory to explore how textile dyeing can enhance product quality. 

This course provides an overview of world and East Asian economic history from the late 19th century to the present and cultivates a historical approach essential to understanding economics by introducing major research topics pertaining to each era and from diverse fields. 

This course builds independent research ability by introducing students to reading key historic documents, conducting research on modern economic history, and writing research papers. The course encourages a comparative historical perspective by juxtaposing European economic history with that of China, Japan, and Korea. 

The context and behaviors of computer usage have been rapidly changing as the shift of computer use environments moved from desktop computers to mobile devices to the Internet of Things, leading to the remarkable appearance of Web 3.0 technologies including XR/AI/Sensor/Blockchain which have been called new design frameworks of NPD processes that may support the big step from “interacting with computers” to “interacting with AI.”  

Now advanced enterprise architectures are rapidly adopting the “Cognitive Internet of Things.” This drastic shift signifies a fundamental game changer for the UX matters.  

This course converts the initiative in the design management strategy into the study of new HCI/UX design and analysis methods in relation to cognitive science theories and design methodologies, bridging contemporary and in-depth academic interests and approaches in the field. 

Students will explore the theoretical framework of human-computer interaction (HCI) and will build an understanding of HCI-based UX research methodology, the user research process, and practical methodologies, and will engage with the current topics of HCI/UX research and the practical use of convergence studies. 

This course primarily focuses on economic analysis in terms of welfare. Topics include how to evaluate market allocations based on efficiency, how to achieve efficient allocations through the market, and when the market fails in achieving efficient allocations.  

Students will study market structures besides the competitive market such as standard monopoly (uniform pricing), monopoly behavior (price discrimination) and oligopoly (basic concepts in game theory are also covered).  

Additionally, the course will consider exchange, production, welfare, social choice (e.g., an investigation of voting rules), and externalities (If time allows).  

This course emphasizes the development of microeconomic models to analyze economic decision-making of agents and provides students with the basic toolkit of microeconomic theory in preparation for advanced further coursework.  

Prerequisites: Principles of Microeconomics, Basic calculus
