Gabriel Ahlfeldt

Professor Gabriel Ahlfeldt is a Professor holding the Chair of Econometrics at the School of Business and Economics, Humboldt University in Berlin. He maintains significant academic affiliations including Visiting Professor at the London School of Economics, faculty member of the Berlin School of Economics, and fellow/affiliate positions with the Centre for Economic Policy Research (CEPR), Centre for Economic Performance (CEP), and CESifo.

Professor Ahlfeldt identifies as a quantitative spatial economist and applied empiricist. His primary research field is urban economics, but his work spans multiple disciplines including:

• Environmental economics
• Real estate economics
• Labor economics
• Political economy
• Financial economics

His research focuses on spatial frictions, urban density, housing markets, and the economics of skyscrapers, often employing advanced econometric techniques and spatial modeling.

Professor Ahlfeldt teaches the PhD course 'Quantitative Spatial Economics' at the Berlin School of Economics and co-organizes the Berlin School of Economics Quantitative Spatial Economics Research Seminar (www.bqse.de). His recent publications demonstrate a consistent focus on spatial economic phenomena, with particular attention to how physical and economic geography shapes urban development, housing markets, and quality of life metrics.

His notable scholarly contributions include:

• Measuring Quality of Life under Spatial Frictions (2024)
• Housing-Consumption Channel of Mortgage Demand (2024)
• The Skyscraper Revolution: Global Economic Development and Land Savings (2023)
• Prime locations (2022)
• A granular spatial model (2022)

Professor Ahlfeldt has developed several research toolkits that have become valuable resources for spatial economists, including the MRRH2018-toolkit for quantitative spatial models and the ARSW2015-toolkit for analyzing urban density. His work bridges theoretical economic modeling with empirical analysis of real-world urban phenomena.
