Welcome to the Chair of Macroeconomics

Christopher Schang

We welcome Christopher Schang (Ph.D. in Economics, European University Institute) who joins our team as a postdoctoral researcher. Christopher's thesis in the field of quantitative macroeconomics focuses on demographic change, alongside monetary, fiscal, and macroprudential policy.

Seminar in Macroeconomics I (BA/ MA): Healthy Economy? Health Inequality and Insurance Policy

In the seminar, we will explore the economic dimensions of health, focusing on three key aspects: (1) Conceptualizing and measuring health, (2) the relationship between health heterogeneity and economic outcomes like income and wealth, and (3) the role of (public) health insurance and policy. 

Two of us presented at the "Deep Learning for Dynamic Stochastic Models Conference 2025": Johannes Brumm, with the keynote address, "Tensor-Train Decomposition for High-Dimensional Economic Models", and Lukas Frank ("Mastering Stochastic OLG Models in Continuous Time"). 

At the 11th KIT Championship on July 5, 2025 (upper photo), the "Macromaniacs" improved their 4x10km team time from 2023 (lower photo) by 8 minutes, finishing in 3:09:21. In 2026, we're aiming to break the 3-hour mark!

In this seminar, we will employ macroeconomic models to evaluate and compare some of the most common political approaches to mitigate and adapt to climate change. In particular, we focus on the effects of carbon taxation and the use of the resulting tax revenue.

Computational Macroeconomics (BA)

The Digital Economy: Micro and Macro Perspective (BA)

Advanced Topics in Economic Theory (MA)

Seminar in Macroeconomics: Climate Policy - Who Gains and Who Loses? (BA/MA)

The Paper "When Interest Rates Go Low, Should Public Debt go High?" by Johannes Brumm and co-authors was published in the American Economic Journal: Macroeconomics in October, 2024.

Prof. Brumm discussed the paper "Taxing Sudden Capital Income Surges" by Wei Cui and Jianjun Miao at the conference Global Challenges and Channels for Fiscal and Monetary Policy hosted by the ECB and the IMF in July 2024.

On July 20th 2024, the Chair of Macroeconomics is hosting the first KIT Quant Macro Day! We will cover topics in the range of Heterogeneous Agent Models, Quantitative Modeling in Labor Economics and Deep Learning in Economics at the TRIANGLE SPACE (Schedule).

The article discusses the current federal budget from the perspective of intergenerational fairness, with contributions from Prof. Brumm and three members of the Bundestag. (Article in German only)

In this interview, Johannes Brumm answers questions regarding government debt, the debt break and the current special assets of the German Federal Government. Additionally, he outlines concepts for a fiscal policy that takes all future generations into account. (Interview in German only)

Johannes Brumm receives a European Research Council (ERC) Starting Grant. The project advances solution methods for high-dimensional stochastic overlapping generations (SOLG) models to address applications related to public debt and pension reform.
The project SOLG for Policy will be funded for five years with a total amount of about 1.5 million Euro. We are happy that our team will grow and that we will be able to address questions of high relevance for society.
