This book provides an introduction to macroeconomics through selected readings. There are three central aims. Firstly, to introduce the student to different theoretical approaches to our understanding of the functioning of a market economy. Secondly, the readings are concerned with the predictions of theories and relating them to the evidence where appropriate. Finally, the book highlights the policy implications of the various theoretical approaches and the means by which a number of macroeconomic problems can be tackled. The student is made aware that the evidence does not always provide unambiguous answers to economic problems and many important controversies remain in macroeconomics.
