Aimed at advanced undergraduate and graduate students in economics, banking, and finance, this is a core textbook for the financial markets, institutions, and regulation option of courses in financial economics. It integrates modern theories of asymmetric information into the analysis offinancial institutions, relating the theory to current developments. The text begins with an analysis of adverse selection in retail financial products like life assurance before looking at open capital markets where trades and prices provide information. It then progresses to the more complex areas of corporate governance and financial intermediation in whichinformation is confidential and moral hazard and verification problems become important. These chapters study the various mechanisms that the financial markets have developed to allow investors to delegate the management of their assets to others. This analysis is used to show how regulation canreduce the risk of financial failure and how legal, accounting, and regulatory mechanisms can help shape a country's corporate and financial architecture. These difficult theoretical concepts are conveyed through the careful use of numerical illustrations and topical case studies. Each chapter ends with a set of exercises to test and reinforce students' comprehension of the material. Worked solutions are provided for the numerical exercises.
