The Friedman-Lucas Transition in Macroeconomics: A Structuralist Approach considers how and to what extent monetarist and new classical theories of the business-cycle can be regarded as approximately true descriptions of a cycle's causal structure or whether they can be no more than useful predictive instruments. This book will be of interest to upper-division undergraduates, graduate students, researchers and professionals concerned with practical, theoretical and historical aspects of macroeconomics and business-cycle modeling.
