How Do Robots Replace Workers? Towards a New MACROeconomic MODelling Approach (MACROMOD)

Team: Prof. Dr. Marianne Saam

External cooperation partner: Prof. Dr. Konstantin M. Wacker (University of Groningen)

Description: New technologies such as AI and robotization pose a key societal challenge. Existing research has analyzed labor market effects of robotization quite extensively using, for example, detailed data for one country or industry-level data across countries. What is currently missing is a tighter integration of such empirical evidence into standard macroeconomic frameworks that give a stylized picture of the overall economy for policy analysis. Overcoming this gap is important because it allows analysts to incorporate labor market and output (“growth”) effects of automation into macroeconomic models based on empirically reliable estimates. This Seed Funding project provides the basis for further joint research activities in this area between RUG and UHH.

Funding: Joint seed funding of University of Hamburg and University of Groningen

Duration: 2025 - 2026


User Behavior and Search Patterns on EconBiz

Team: Oliver Hahn, Prof. Dr. Ralf Krestel, Dr. Tamara Pianos, Prof. Dr. Marianne Saam (all ZBW)

Estimating the Substitutability of Robots and Human Labor – A Production Function Approach

Team: Prof. Dr. Marianne Saam

Partners: Dr. Anne Jurkat (International Federation of Robotics), Julian Salg (University of Frankfurt)

Description: We estimate the substitutability of robots and human labor based on a two-level CES production function using data from a panel of 10 countries and 9 industries from 1993 to 2007.

Funding: Internal funding UHH

Duration: 2021 - 2024


Replication Studies in Doctoral Theses

All doctoral theses written at the Chair of Digital Economics include one replication study. These studies begin with a reproduction of the original research and usually extend it by using new data or methods. Current replication studies in progress include the following papers:
