Document Summary

6. 1 assessing the health of the economy: performance and policy. Macroeconomics studies the behavior of the economy as a whole. It is primarily concerned with two topics: long-run economic growth and the short- run fluctuations in output and employment. Business cycle: recurring increases and decreases in the level of economic activity over periods of years. Recession: a period of decline in total output, income and employment. Economists collect data about the economy to measure how well or poorly it is running. Modern economic growth: the historically recent phenomenon in which nations for the first time have experienced sustained increases in real gdp per capita. Under modern economic growth, the annual increase in output per person is often not large. The vast differences in living standards seen today between rich and poor countries are almost entirely the result of the fact that only some countries have experienced modern economic growth.
