This book provides a systematic approach to analyzing macroeconomic developments, focusing on macroeconomic accounts, analysis, and the effects of selected policies on a nation's economy. The first part of the book describes the data, accounts, and analysis of the four main macroeconomic sectors -- real, external, fiscal, and monetary -- and discusses the accounting and economic relations among these sectors, using a flow of funds approach. Key indicators are presented for each sector and used to show how macroeconomic developments can be assessed and problems identified.The second part of the book discusses fiscal, monetary, and exchange rate policy and their economic implications. These policies, along with selected structural reforms, are compared along several dimensions and shown how they can be used, in various combinations or individually, to address a variety of macroeconomic difficulties.
