Johannes Spinnewijn is a Lecturer at the Department of Economics at the London School of Economics. Prior to joining LSE, he completed his PhD at the Massachusetts Institute of Technology. His work is on various topics in public economics including the design of social insurance and tax systems. A central topic in his work is the design of policies when people are subject to behavioural biases. In particular, he has been studying biases in job seekers’ perceptions of employment prospects and evaluating the role of information frictions for interventions in the health insurance market. He integrates theoretical and empirical methods, most recently to evaluate the optimal timing of unemployment benefits. Johannes teaches and advises students in public economics in the PhD, MSc and MPA program at LSE. He is also affiliated with the CEPR and the Institute for Fiscal Studies.
