The aim of this online project is to provide fresh thinking on the question of how risk is perceived and managed. The issue of risk management has leaped to near the top of many companies' agendas since at least 2008 and the outbreak of the great financial and economic crisis. Gauging opportunity and risk has always been a central part of what asset managers do. Even in this respect, however, the complexity of risk management and its importance for successful investment have increased significantly. And it is by no means only the purely financial dimension that plays a role here: psychology, sociology, ethics and many other disciplines can potentially be relevant as well. Like an atlas, Measuring Risk casts the spotlight on a wide range of risk dimensions. Academics and practitioners as well as nine guest speakers from Union Investment's risk management conferences have contributed articles, essays and interviews to this interdisciplinary project. By enabling the reader to see the proverbial bigger picture, we would like to make an inspirational contribution towards refining the practice of risk management and establishing a new risk culture.
