Claus Thustrup Kreiner

Professor Claus Thustrup Kreiner is a leading economist at the University of Copenhagen's Center for Economic Behavior and Inequality (CEBI) and serves as a CESifo Research Network Fellow directing the Public Economics research area. His institutional affiliations bridge cutting-edge academic research with policy-relevant analysis through Denmark's premier economic research hub and the international CESifo network.

His research spans Public Economics, Labour Economics, and Macroeconomics, focusing on critical societal challenges: the tension between economic efficiency and rising inequality, adaptive social insurance design for aging populations, and resilient tax systems amid globalization. His work uniquely integrates theoretical rigor with empirical validation using Scandinavian administrative data, examining how tax competition, migration, and intangible capital reshape fiscal policy frontiers.

Professor Kreiner leads the Center for Economic Behavior and Inequality (CEBI), which serves as Denmark's focal point for research on economic inequality and behavioral responses to policy interventions. The center's interdisciplinary approach combines microeconomic theory with empirical analysis to address fundamental questions about fairness perceptions, social mobility, and optimal policy design in modern welfare states.
