"Professional service firms are critical agents of contemporary economies and understanding them has become a central focus of recent scholarship. This very timely and well organized Handbook brings together several leading scholars who explore how we might think and theorize about professional service firms and their entrepreneurial behaviours. The Handbook will become a key source for the growing community of researchers in this area. - Royston Greenwood, University of Alberta, Canada" © Markus Reihlen and Andreas Werr 2012.
