ECN401 Microeconomic Theory with Applications
This course aims to teach students how to apply principles from microeconomic theory to structure and address real-world problems. Students will get a solid understanding of the microeconomic models of consumer and firm decision-making behavior, why markets sometimes fail, and the use of interventions to achieve the best possible outcomes for society. However, rather than just teaching students the theoretical principles of microeconomics, we will also show how it is practiced by firms, ministries, and organizations and thereby demonstrate the direct relevance for the student’s professional life.
To achieve this goal, the course is organized around several distinct topics. For any given topic, we will cover the most important microeconomic theories to structure ideas into hypotheses and predictions about what we expect to happen under different conditions. Next, we want to think about ways to test the theory and discuss different empirical approaches that enable us to draw conclusions about causal relationships. Importantly, conclusions are drawn by bringing both elements together; We use real-world data to test theory and use theory to interpret real-world data. By highlighting the interconnection between theory and empirical evidence, students will appreciate the usefulness of economic theory, the importance of careful analytical thinking when conclusions are drawn, and that conclusions based on intuitions and preconceptions can be very misleading or sometimes right out wrong.
For example, consider the potential effects of a merger between two competitors. If the merging firms are close competitors, the merger will induce upward price pressure. On the other hand, if the merged firm is more efficient and marginal cost decreases, this will cause downward price pressure. Competition Authorities will not allow a merger if they expect it to lead to a price increase. How should they decide whether to allow a specific merger or not?
Examples of topics that are covered in the course (non-exhaustive list):
- The microeconomics of energy subsidies to households; Efficiency, equity, and welfare effects
- Optimal taxation, tax salience, and tax incidence
- Behavioral economics; rationality and irrationality; social preferences and nudging
- Strategic behavior by firms in entry situations and the role of commitment
- The use of pricing pressure indicators to provide proxies for the welfare effects of mergers
- Good and bad sources of market concentration
- Tight labor markets and individual demand for education
The course will give students an understanding of how we can apply economic theory at a broad level.
By the end of the course, the student will be able to:
- Discuss basic insights within production and consumer theory
- Describe different tools that can be used to study the interaction between firms in the marketplace to make predictions about a firm's strategy
- Explain implications of uncertainty and asymmetric information for economic transactions
By the end of this course, the students will be able to:
- Perform basic microeconomic analysis of real-world problems
- Formulate problems involving strategic interaction as non-cooperative games and use the appropriate solution concepts
- Draft a suitable empirical design that provides data to test the models
By the end of this course the students will be able to:
- Read research papers or professional reports related to topics in the course and reflect upon how conclusions are drawn in light of theory and empirical design
- Think analytically about problems that involve decisions made by firms and individuals
Plenary lectures and prepared class discussions.
Lectures will be held physically in the auditorium, with no streaming or recording. It's essential that students attend class, as we will emphasize discussion and dialogue in the lectures.
Guest lecturers from practitioners (e.g., Norwegian Competition Authority, Oslo Economics, Norwegian Tax Authority).
Students should be familiar with the material covered in the undergraduate methods and microeconomics courses.
Two compulsory written assignments (30% each) and a 3-hour school exam at the end of the term (40%).
The assignments can be handed in individually or in groups of maximum two students. Students will be given approximately two weeks to complete the assignments. The assignments must be written in English.
Students can retake each component independently.
Grading scale A - F.
The course will be based on a selection of real-world examples and empirical articles. A list of academic, popular science, and case study materials, will be announced at the start of the course.
In addition to these, students are expected to read the relevant chapters in:
Samiran Banerjee (2021) Intermediate microeconomics: A tool-building approach. 2nd edition (London: Routledge)
Avinash Dixit, Susan Skeath, and David McAdams (2020) Games of strategy (5th edition) (Norton)
