Introduction

**Course Review: Game Theoretic Analysis for Business Research (2)** If you are diving into the intricate world of business strategy and economic decision-making, I highly recommend the course *Game Theoretic Analysis for Business Research (2)* offered on Coursera. This course serves as a continuation of its predecessor and delves deeper into the application of game theory in business contexts, particularly focusing on the theme of information asymmetry. ### Course Overview This course is meticulously designed for those looking to enhance their analytical skills and theoretical understanding of business dynamics influenced by information disparities. Throughout the course, students will explore essential concepts, including moral hazard, adverse selection, and screening problems, all articulated through practical examples from everyday life. By the end of the course, participants will have developed a foundational expertise in conducting theoretical research related to information asymmetry within business environments. ### Syllabus Breakdown 1. **Introduction to Information Economics**: The course begins with a light and engaging overview of information economics. The instructor presents complex ideas simply, using relatable real-world examples to elucidate key concepts like information asymmetry, moral hazard, adverse selection, screening problems, and signaling. 2. **Screening Models**: In this section, students will learn to construct economic models that illuminate the often invisible dynamics of information asymmetry. A classic binary hidden information screening model is introduced here, providing foundational techniques for problem-solving and revealing the economic intuitions and managerial implications of equilibrium solutions. 3. **Application of Screening Models**: Building on the previous week’s learning, the course incorporates a supply chain management context, showcasing how screening models can be complicated yet powerful tools to derive counterintuitive yet interpretable research conclusions. 4. **Messaging Models**: Transitioning to signaling issues, this module teaches participants to construct and solve messaging models, exploring how decision-makers can convey hidden information through their choices, influencing perceptions and expectations. 5. **Application of Messaging Models**: The course culminates with a practical example involving the sales and procurement of expensive medical equipment. This application not only highlights the complexities in real-world scenarios but also demonstrates how messaging models can be useful for interpreting observable phenomena in various settings. ### Why You Should Take This Course - **Practical Application**: One of the standout features of this course is its emphasis on bridging theory with practice. The use of real-world scenarios ensures that the theoretical concepts learned are not merely abstract but applicable in everyday business situations. - **Engaging Teaching Style**: The instructor’s approach to breaking down complicated economic theories into digestible lessons makes learning enjoyable and insightful. This methodology enhances retention and encourages active participation. - **Skill Development**: By the end of the course, you will not only grasp the theoretical boundaries of information asymmetry but also acquire the practical skills necessary to analyze and conduct research in complex business environments. - **Collaboration and Networking**: Engaging with fellow learners fosters a rich environment for collaboration. This networking is invaluable for anyone interested in business research or strategy. ### Final Recommendation *Game Theoretic Analysis for Business Research (2)* is not merely an academic exercise; it's a vital educational journey that equips students with the tools to navigate the nuanced realm of information economics within business contexts. Whether you are a student, a professional, or someone with a keen interest in enhancing your understanding of business strategy through the lens of game theory, this course is an excellent investment in your educational and professional development.

Syllabus

資訊經濟學簡介

在本週的課程中，我們將用輕鬆愉快的方式，為資訊經濟學與這門課做一個簡單的介紹。我們將用一些生活中的例子說明幾個重要的概念，包括資訊不對稱、道德風險、逆向選擇、篩選問題和訊號問題等，並且來闡述。

篩選模型

本週我們將進入模型的世界，學習如何用經濟模型來描述看不見、摸不著的資訊不對稱。我們將從篩選問題出發，用一個簡單的定價問題來介紹最經典、最基本的二元隱藏資訊篩選模型、其求解的方式，以及均衡解能帶給我們的經濟直覺與管理意涵。

篩選模型之應用：篩選零售夥伴的需求預測能力

延續上週的課程，本週我們用一個供應鏈管理的例子，一方面介紹在更為複雜的環境中如何建立與分析篩選模型，一方面也展示篩選模型能如何被應用以獲得「不直觀，但可以被解釋」的研究結論。

傳訊模型

本週起我們轉向另一個重要的議題：訊號問題，並介紹如何建構與求解傳訊模型。我們將從最基本的二元決策出發，說明如何建構模型，以探討一個決策者如何透過非 A 則 B 的選擇去傳遞自身的隱藏資訊。我們也將介紹如何建構與分析連續決策傳訊模型。

傳訊模型之應用：傳遞醫療儀器之可靠度訊號

延續上週的例子，我們以一個貴重醫療儀器銷售與採購的例子來說明傳訊模型的應用，一方面介紹在更為複雜的環境中如何建立與分析傳訊模型，一方面也展示傳訊模型能如何被應用以解釋實際場域中觀察到的現象。
