In Conclusion
Understanding the meaning and measurement of macroeconomic variables is vital for your ability to evaluate the abundance of information you receive through various forms of the media about the state of the aggregate economy. The difficulties faced by the team of International Monetary Fund (IMF) economists with which we opened the chapter are not that different from the problems each of us faces in understanding what is happening in the economy. The concepts and variables you have discovered in this chapter are used over and over again in the various applications discussed in this book. We use the concepts of real gross domestic product (real GDP), the inflation rate, the unemployment rate, and so forth almost everywhere in our study of macroeconomics.
