THOSE WERE THE DAYS... RUTCOR 1983-1987

Yves Crama

RUTCOR turned 25 year old in 2008. I was fortunate enough to be among

the very first students

to attend the brand new Interdisciplinary Program in Operations

Research, from 1983 to 1987, under

the guidance of Peter Hammer. In this presentation, I would like to

share with the audience some memories of those exciting times.

MODELS OF VOTING POWER IN CORPORATE NETWORKS

Yves Crama

Abstract: In this talk, we propose to rely on power indices to measure

the amount of control held by

individual shareholders in corporate networks. The value of the indices

is determined by a complex voting game

viewed as the composition of interlocked weighted majority games; the

compound game reflects the structure of shareholdings.

We describe an algorithmic approach which allows to deal with the

complexity of computing power indices in

real-world financial networks, and we identify some of the research

questions which arise in connection with this approach.
