Rational expectations has unquestionably become the standard way of modeling expectations in macroeconomics. Like the successful and widely-adopted first edition, this new edition is designed to explain the concept of rational expectations and its implications for macroeconomics. It fills the gap between introductory macroeconomics texts in which expectations formation is incidental and the technically advanced texts and journal literature on rational expectations. In this new edition, the authors have both extensively revised the presentation of much of the material covered and extended the coverage to include recent developments in the subject, most notably in the theory of aggregate consumption and the theory of real business cycles. von Attfield, C.
