Macroeconomics makes modern macroeconomics with its focus on imperfect competition, interest-rate setting central banks, and knowledge - based growth accesible to undergraduates. It provides micro-foundations for the Philips curve, for persistent involuntary unemployment, for aggregate consumption and investment behaviour, and for inflation-targetting. It is based on the mainstream monetary macro model now used widely by academics and policy makers and showsstudents how to use it to understand a broad range of real-world macroeconomic behaviour and policy issues. It is also designed to appeal to graduate students, non-specialists in macroeconomics, professional economists and those from related disciplines who want a guide to the complexities of modernmacroeconomics and to understand contemporary policy debates.
