the economy of a country or region; it studies economic changes in the aggregate, collecting data on production, unemployment, inflation, consumption, investment, trade, and other aspects of national and international economic life. Policymakers depend on macroeconomists' knowledge when making decisions about such issues as taxes and the public budget, monetary and exchange rate policies, and trade policies?all of which, in turn, affect decisions made by individuals and businesses. This volume in the MIT Press Essential Knowledge series offers an introduction to the basics of macroeconomics accessible to the noneconomist. Readers will gain the tools to interpret such economic events as the 2008 financial meltdown, the subsequent euro crisis, and the current protectionist dynamics seen in some developed countries.The author, an academic economist and two-time Chilean Finance Minister, devotes a substantial part of his analysis to economic development, explaining why some countries achieve continuing economic growth while others become stagnant. He discusses the links between economic activity and employment; employment and unemployment rates; factors behind economic growth; money, inflation, and exchange rate systems; fiscal deficits; balance of payment crises; consumption and savings; investment decisions; fiscal policy; and the process of globalization and its macroeconomic implications.
