Risk models, like all tools that describe and predict behaviors, possess strengths and flaws that can yield consequences both intended and unintended. In this collection of original essays, finance professionals and professors from around the world examine the assumptions and expectations that underlie both financial risk models and the practices and institutions they have engendered. Contributors analyze and evaluate current systems while summarizing our understanding of certain types of risk and describing emerging trends. Subjects range from risk reporting and risk forecasting to enterprise risk management and the effect of behavioral finance on compensation systems. Encouraging practitioners and the academic community to look at risk as it hasn't been looked at before, this book seeks to encourage critical thinking and innovation.
