László Á. Kóczy is a professor at the Finance Dept and the director of QSMS. He graduated from the University of Cambridge reading Mathematics and from KU Leuven in Economics, where he also completed his PhD under the supervision of Luc Lauwers. He has spent some time at Maastricht and Óbuda Universities before joining BME. He is also affiliated with the Centre for Economic and Regional Studies. He has published 50 papers in the fields of cooperative game theory, voting, economic theory and scientometrics. He published his book on Partition function form games in 2018 by Springer. He is currently working on the theory and applications of cooperative games, power indices, the apportionment problem and some experimental papers. >>>download_CV
