This course module discusses several of the most practically relevant econometric and statistical methods for empirical research and data analytics (e.g. in economics and social sciences) along with their underlying assumptions and properties. It also presents applications of these methods in real-world data using the statistical software “R (studio)”. The course module consists of a lecture and 4 PC lab sessions (quizzes). This course consists of asynchronous independent study periods, 5 online meetings, and 4 PC labs and quizzes. The topics covered in the lecture include:

1. The difference between causation (e.g. education has a causal effect on wage) and correlation (subjects with higher education have higher wages, but this may be driven by other factors than education as for instance ability); the intuition of experiments for assessing causation.

2. Linear regression (OLS - ordinary least squares) to assess the association of one or several variables (e.g. education, age,...) with an outcome of interest (e.g. wage).

3. Quantile regression to conduct empirical analyses at particular outcome ranks (e.g. for the median earner in the wage distribution).

4. Nonlinear regression (probit regression for binary outcomes like working vs. not working, tobit regression for censored outcomes).

5. Flexible methods for causal analysis (such as for evaluating the effect of training on earnings): matching, inverse probability weighting, doubly robust estimation.

6. Instrumental variable regression to assess the effect of endogenous variables (that are not random).

7. Regression discontinuity designs to assess the effect of a variable (e.g. health treatment) which is assigned based on a running variable (e.g. health index).

8. Panel data regression and “Differences-in-Differences” estimation when subjects are observed at several points in time.

9. Synthetic control methods for evaluating the effect of an intervention (e.g. of a health policy) on a single unit (e.g. a single region introducing the health policy).

10. Bootstrapping (resampling from the original data, e.g. for variance estimation).

11. Time series regression, e.g. for modeling stock prices or GDP growth over time.

This course provides a user-friendly exploration of key issues and concepts in machine learning, with an emphasis on practical applications in economics and management. Students will understand the difference between predicting outcomes and understanding cause-and-effect relationships, delve into regularised regression techniques such as Lasso and Elastic Net, explore tree-based methods such as Random Forest, and learn about resampling methods such as bagging and cross-validation. The course also covers deep learning and unsupervised machine learning techniques. In addition, students will be introduced to a selection of advanced topics for example causal machine learning, reinforcement learning, GANs and LLMs. Using a hands-on approach and the industry-standard software R, the course facilitates the practical application of theoretical concepts, ensuring that students gain valuable skills in implementing machine learning models.

Agenda:

• Block 1: Introduction

• Block 2: Regularised Regresssion

• Block 3: Trees and Deep Learning

• Block 4: Unsupervised ML

• Block 5: Advanced ML Topics

This module addresses practical issues of data analytics, e.g., data processing and data visualisation, and discusses empirical examples (or use cases) in a seminar format. To this end, various research projects might be assigned to different groups of students and the group work is to be presented in the course. The learning goal is that students get acquainted with practical issues of data analytics (such as data cleaning, plausibility checks, etc.) in a hands-on manner and learn to realise their own empirical projects by working through all steps from data acquisition and processing to the quantitative analysis and the interpretation of the results, using R, Python, or other appropriate statistical software.

A major part of economic activity takes place within or between organisations. In particular, many complex transac-tions can only be carried out with the involvement of organisations. It is thus crucial for economists and managers to understand the economic purpose of organisations, how organisations function, and how they should be de-signed.

The module consists of two parts. The first sheds light on the fundamental questions of why firms exist and what their boundaries should be. We cover classic and more recent theories of the firm to understand firm scope and to analyse decisions of vertical integration and outsourcing. The second part investigates the internal organisation of firms and how they should be designed to reach their goals. We rely on theories from economics, management, and related fields to analyse how explicit and implicit incentives affect performance and how organisations can design their incentive systems to motivate employees. Across all topics, we rely on empirical evidence in the form of field data, experiments, and case studies to critically evaluate and, if possible, further develop the theories.

Key themes and concepts:

Part I – Foundations and Boundaries of Organisations:

• Incomplete contracts

• Relationship-specific investments and hold-up

• Transaction Cost Economics

• Property Rights Approach

• Contracts as Reference Points

Part II – Motivation Problem and the Internal Organisation of Firms:

• Principal-Agent model

• Performance pay

• Multi-tasking

• Ratchet effect

• Tournament theory

• Intrinsic motivation and social motivators

(Autumn Semester 2024)

The course introduces students to economic approaches for understanding, analysing, and evaluating human decision making.

Block I starts a selected collection of common bias and heuristics that are often observed in human decision making.

Block II introduces the economic foundations of decision making such as basic concepts of preference, axioms, states, acts, and outcomes. We will use decision tree to describe simple decisions under uncertainty, and discuss several systematic, empirical deviations from the expected utility theory (EUT).

Block III deals with decision making for future selves.

Block IV investigates decision making with strategic interactions. We will introduce game theory and a variety of typical strategic constellations as well as several useful solution concepts. Finally,

Block V presents organisational decision making and a touch of policy implications from natural experiments.

This module provides master students with a comprehensive introduction to marketing and consumer behavior. The conceptual foundations of marketing and consumer behavior form the core of the course. The course is structured around four different perspectives on marketing.

• Theoretical perspective

• Information-related perspective

• Strategic perspective

• Instrumental perspective (marketing mix)

Within this structure, current developments in marketing and consumer behavior are discussed (e.g., AI in marketing, current research findings), and different tools to measure and analyze consumer behavior are introduced in R exercises. It is demonstrated how you can draw sound conclusions from such analyses and translate these conclusions into a coherent marketing strategy.

This class will be building on major leadership and business ethics theories with the aim to offer concrete recom-mendations for individuals who want to become more leader-like, effective, and ethical in a formal leadership role. This module is made of two different parts, which are inherently linked with one another.

The first part will investigate leadership theories. It will focus on the mindful engagement model as a systematic model to approach one’s development as a leader, review the large literature on personality traits to better under-stand the origin of one’s own behaviours, and discuss the full range model of leadership with its four styles: Trans-actional, Instrumental, Transformational, and Charismatic. We will also discuss how the effectiveness of leadership styles depends on the specific context.

In the second part, we will start by discussing the relevance of business ethics for today’s managers. We will start by reviewing the major philosophical approaches that inform morality and underpin major ethical decisions. We will then apply these principles to different examples, helping students distinguish among the different morality ap-proaches. Finally, we will discuss contemporary cases and important ethical questions for managers.

Key concepts seen in this class include (among others):

Part 1:

• Leadership styles and behaviors

• Traits

• Charismatic leadership

• Contextual leadership

• Situational awareness

Part 2:

• Ethics

• Morality

• Utilitarianism

• Deontology

• Value-based leadership

The course Competitive and Corporate Strategy introduces students to the concept of competitive analysis and its implications for strategic decision making in firms. To enable students to analyse and establish the position of a firm within an industry, it covers essential topics and theories, such as the creation of competitive advantage, horizontal integration, and the resource-based view of the firm. After completing this course, students can identify, analyse, and synthesise data and information that supports company decision-making to optimise a firm’s strategic positioning.

We live in an increasingly digital world and economy. Information technologies have already transformed the way business is done and will continue to do so. This course covers basic theory in digital economics, for instance, network effects, value creation models, digital business models and market modelling.

The course introduces the most prominent theories and proposals related to economic growth and evaluates them critically from a sustainable development perspective. We analyse and model the relationships between economic, demographic, and environmental variables, and try to understand their implications for growth rates, inclusive growth, international development, and inequality.

This course focuses on the role of government policy in a market economy and on the challenges that arise in the context of the regulation of externalities and generating government revenue. It covers the theoretical and empirical evaluation of public policy as applied to a diverse set of important economic problems such as, for instance, firm concentration and market power, climate change and scarcity of natural resources, or inequality and redistribution.
