This book identifies two market forces that impact PMSCs' military effectiveness: local or conflict-level competition and global or industry-level competition. Specifically, Seden Akcinaroglu and Elizabeth Radziszewski challenge the assumption that interventions by profit-driven coporations are likely to destabilize areas engaged in war, and provide data that private contractors do contribute to conflict termination under certain circumstances. They argue that competitive market pressure creates a strong monitoring system and that the company's corporate structure and external competitive environment in a given conflict help to explain the variance in accountability to clients. Including an analysis of data on international PMSCs' interventions in civil wars from 1990-2008, Akcinaroglu and Radziszewski show the impact of competition on companies' contribution to the termination of different types of civil wars.
