This is a book about traders in financial markets: what they do, the kind of people they are, how they perceive the world they inhabit, how they make decisions and take risks. This is also a book about how traders are managed-the best and the worst examples-and about the institutions they inhabit: firms, markets, cultures and theories of how the world works. How these institutions function, how traders are managed, and how traders view the world, all have profound effects on the wider financial environment. This book explores these relationships and their implications theoretically and empirically. The data discussed in this book on a three-year project researching the psychological and social influences on the behavior and performance of traders in investment banks. One hundred and eighteen traders and managers in four leading organizations participated. Data was collected through semi-structured interviews supplemented by questionnaries, measures of personality, risk propensity and a novel computer based measure designed to assess illusion of control and other cognitive biases. The authors' approach to writing this book is explicitly interdisciplinary. hey draw on sociology, psychology and econics in order to illuminate the work of traders and the world they inhabit. The book is a significant contribution to the growing body of research and literature suggesting that if we are to effectively understand financial markets and the actors who inhabit them, the insights of neo-classical financial economics need supplementing with a broader range of social science approaches. The book will be of value to researchers interested in the functioning of financial institutions and markets, to those with an interest in market regulation and to practitioners wishing to benefit from an analytical perspective on the challenges facing traders and their managers.
