Sebastian Siegloch

Sebastian Siegloch is a Professor of Economics at the University of Cologne, where he serves as Head of the Department of Economics and Director at the FiFo Institute for Public Economics. He is also a member of the DFG Excellence Cluster ECONtribute, a joint initiative of the Universities of Cologne and Bonn. His extensive research network includes fellowships at CEPR, CESifo, CReAM, and IZA, as well as a Research Associate position at ZEW.

Professor Siegloch's research focuses on the intersection of Public, Labor, and Urban Economics, examining how economic policies affect market outcomes and shape inequality. His methodological approach emphasizes the use of large datasets and quasi-experimental variation to identify causal effects. Key research areas include taxation (corporate, profit, and property taxes), social insurance systems (particularly disability insurance), housing policy, and regional economic development.

His publication record demonstrates exceptional quality, with articles in top journals including Econometrica, American Economic Review, and American Economic Journal: Economic Policy. Recent work includes influential studies on disability insurance privatization, regional firm subsidies, and the effects of property taxation. His 2025 Econometrica paper on disability insurance represents particularly significant contributions to understanding public-private insurance interactions.

Professor Siegloch's research has important policy implications for tax design, social safety nets, and regional development strategies. His work on disability insurance privatization provides crucial insights for welfare systems facing fiscal pressures, while his research on property taxation offers evidence-based guidance for housing market interventions. His methodological contributions, particularly in event study designs, have advanced empirical approaches across multiple economics subfields.
