This textbook survey of the current state of macroeconomics looks at alternative approaches to the subject. The book divides into six parts. The first is introductory and gives a general background for a better understanding of the recent debates under discussion. It focuses on schools of thought which have been prominent in macroeconomics over the last two decades. The second part looks at the "rational expectations" controversy. The third section examines an issue which has been at the centre of macroeconomic debate since the early 1970s: economic fluctuations. This is followed by a section on wage determination and inflation. Next is a sample of problem-orientated macroeconomic work which also examines a few of the methodological questions such work has raised. The final part concludes by looking at issues in contemporary macroeconomics.
