Macroeconomics Understanding The Wealth Of Nations

In this chapter we show you what macroeconomics is about by looking at some of the big questions that macroeconomists ask: Why do some countries enjoy a standard of living many times greater than others? How does growth in productivity evolve over time? Why does the economy fluctuate between expansions and contractions? What impact do changes in interest rates or in oil prices have upon the economy? We draw out what is distinctive about macroeconomics and contrast it with microeconomics, and illustrate this distinction by focusing on the types of risk that affect individuals and companies.
