ECN431 Data Driven Business Analysis (replaced by BAN440)
As an analyst, manager or economist, there are many important problems and questions you can only address by analyzing data. For instance, "if we increase the price of one product by 5%, what is the likely effect on demand for this and other products in our portfolio, as well as competitors' products?", "what are the consequences of high concentration in grocery retailing?", or "how does regulation change firm and consumer behavior?"
Empirical analysis of problems in business strategy, competition policy and market regulation requires both knowledge of the specific market, appropriate models to account for important mechanisms and structure the analysis, and ability to choose and correctly use quantitative methods to estimate unknown quantities.
In this course, you will analyze data from important markets in the economy, while being introduced to methods and models that will allow you to answer key questions related to competition, consumer behavior, regulation and evolution of business. You will be equipped with sufficient knowledge to interpret empirical results and convey the information in professional settings.
We plan to cover the following markets, with accompanying models and empirical methods:
- Electricity markets
- Competitive supply and demand
- Instrumental variables and estimating systems of equations
- Grocery retailing
- Product differentiation and pricing of product portfolios
- Discrete choice methods
- Machine learning for demand prediction
- Banking and local competition
- Market structure and sunk costs
- Entry cost estimation
- Innovation, intellectual property rights and patents
- Differences-in-differences and value of patents
- Production and distribution of beverages
- Efficiency gains and competition loss in mergers and acquisitions
- Merger simulation and analysis
- Electricity markets
After completing the course, you will:
- be able to interpret economic models of market behavior and imperfect competition
- be able to identify the the relationship between economic models, data, and econometric analysis
- be able to discuss the competitive environment and market structure in several central industries
- be able to use economic models to answer questions related to market structure, entry, effects of mergers, pricing and technological change
- be able to apply economic theory and suitable econometric methods to make sense of market- and firm-level data
- be able to use statistical software to conduct relevant analyses, produce professional tables and figures, and replicate results at a later time
- be able to carry out an independent analysis, for instance as part of a master thesis, or in your future professional career
- be able to present and communicate results of data driven projects in a professional context
Lectures and computer labs.
Econometrics equivalent to ECN402.
Familiarity with basic calculus will be assumed.
In some cases, familiarity with the concepts introduced in ECN433 or ECO427 (such as: supply and demand, Bertrand and Cournot oligopoly models, Nash equilibrium, relationship between market structure and market power) will be helpful; however, such knowledge is not assumed, and the important points will be covered in class.
Credit reduction due to overlap
Cannot be combined with BAN440
Presentation of term paper in English.
The final grade will be based on two individual assignments - a shorter (10%) and a longer one (20%), and a group-based (3-4 students) term paper (70%).
The short assignment will be handed out early February, and the second assignment towards the end of February/beginning of March with two-week deadlines. The topic for the term paper should be chosen by March, and the deadline for the term paper will be in April.
The assignments and term paper must be written in English.
Grading scale A-F
We will use R/RStudio in the lab. It will also be possible to use STATA, Python or Julia to complete the assignments.

Spring. Offered spring 2023.
BAN440 replaces ECN431 from spring 2023.
For students planning to use ECN431/BAN440 as one of the electives to fulfill the requirement of having at least three of the elective courses (equivialent to 22.5 ECTS) from outside the chosen major (i.e. with another prefix than the major), the following applies:
- For students admitted until and including spring 2023, the course can be considered as having both an ECN or a BAN prefix.
For students admitted from the autumn 2023, the course prefix is BAN.
