Hannes Ullrich

Hannes Ullrich is an Associate Professor at the Department of Economics, Faculty of Social Sciences, University of Copenhagen. He also serves as a Research Associate at the German Institute for Economic Research (DIW Berlin) since 2013 and previously held a Research Associate position at the University of Zurich from 2011 to 2019. His work bridges academic research with practical policy applications, particularly in the areas of healthcare economics and digital markets.

Dr. Ullrich's research focuses on empirical industrial organization, health economics, personnel economics, digitization, and discrete choice modeling. His most prominent work examines antibiotic prescribing patterns and resistance, where he has secured an ERC Starting Grant to investigate this critical public health issue. His research demonstrates how machine learning can complement physician decision-making to reduce inappropriate antibiotic use while maintaining treatment effectiveness. Beyond healthcare, he has made significant contributions to understanding digital markets, particularly regarding data value, online tracking, and platform competition, as evidenced by his work on Facebook shadow profiles and returns to data in web tracking.

His publication record shows a clear trend toward interdisciplinary research that combines economic theory with data science methods to address pressing policy questions. Recent work increasingly focuses on the intersection of artificial intelligence and human decision-making in healthcare contexts, while maintaining strong connections to traditional industrial organization questions in digital markets. His research has received attention from both academic and policy communities, with several of his papers generating media coverage and policy discussions.

Among his notable achievements is the prestigious ERC Starting Grant for his research on antibiotic prescribing and resistance. His work has been published in leading journals including the Journal of Human Resources, Quantitative Marketing and Economics, and Economics Letters, demonstrating both theoretical rigor and practical relevance.

Dr. Ullrich actively engages with policy communities through his work at DIW Berlin, where he contributes to research on competition policy, digital markets, and healthcare economics. His research often has direct policy implications, particularly regarding data governance, healthcare innovation, and competition in digital markets. He maintains strong connections between his academic work at the University of Copenhagen and applied policy research at DIW Berlin, creating a bridge between theoretical economics and practical policy solutions.
