Why is it essential to differentiate between real and nominal growth rates of GDP? A. The nominal growth rate is more informative than the real growth rate since it is broader in the sense that it captures both price and output changes. B. The nominal growth rate combines the effect of price changes along with changes in the production of goods and services and thus gives a less clear indication of the impact on living standards. C. It is the real growth rate that is meaningful since it indicates the change in the production of goods and services, a very significant source of improved living standards. D. All of the above. E.

The business cycle is the periodic but irregular up-and-down movement in economic activity, measured by fluctuations in real gross domestic product (gdp) and other macroeconomic variables. a business cycle is typically characterized by four phases—recession, recovery, growth, and decline—that repeat themselves over time. economists note, however, that complete business cycles vary in length. the duration of business cycles can be anywhere from about two to twelve years, with most cycles averaging six years in length. some business analysts use the business cycle model and terminology to study and explain fluctuations in business inventory and other individual elements of corporate operations. but the term "business cycle" is still primarily associated with larger (industry-wide, regional, national, or even international) business trends.
