How does information affect economic relations? What of the strategic issues surrounding the use of information: the make-buy-or-copy decision; the working and failure of markets; and the important role of outguessing each other in a macroeconomic context? Now, to help advanced students and researchers make sense of these and other dizzying questions, Routledge announces a new title in its acclaimed Critical Concepts in Economics series. Edited by David E. M. Sappington, a leading scholar in the field, Information Economics is a 'mini library' that brings together in four volumes the foundational and the very best cutting-edge research. With a comprehensive introduction, newly written by the editor, which places the collected material in its historical and intellectual context, Information Economics is an essential collection and is destined to be valued as a vital one-stop resource.
