Book excerpt: A globe-spanning group of leading law and finance scholars bring together cutting-edge research to comprehensively examine the challenges legislators face in regulating related party transactions in a socially beneficial way. Combining theoretical analysis of the foundations of efficient regulation with empirical and comparative studies, readers are invited to draw their own conclusions on which regulatory responses work best under differing circumstances. The careful selection of surveyed jurisdictions offers in-depth insight into a broad variety of regulatory strategies and their interdependence with socioeconomic and political conditions. This work should be read by scholars, policymakers, and graduate students interested in a critical, much-debated area of corporate governance.
