Economists use real GDP rather than nominal GDP to gauge economic well-being because real GDP is not affected by changes in prices, so it reflects only changes in the amounts being produced. You cannot determine if a rise in nominal GDP has been caused by increased production or higher prices.
Why are comparisons between countries based on GDP statistics often very misleading?
Similarly, the existence of a large hidden economy may make comparisons based on GDP very misleading. For example, comparing the official GDP of the UK and Russia may be misleading because of the size of the hidden economy in Russia. To avoid tax, transactions may go unrecorded and excluded from official statistics.
Why is GDP more commonly used?
GDP is important because it gives information about the size of the economy and how an economy is performing. The growth rate of real GDP is often used as an indicator of the general health of the economy. In broad terms, an increase in real GDP is interpreted as a sign that the economy is doing well.
Why is GDP different in countries?
Differences in real GDP across countries can come from differences in population, physical capital, human capital, and technology. After controlling for differences in labor, physical capital, and human capital, a significant difference in real GDP across countries remains.
What are the problems of GDP?
One problem with GDP is that it does not necessarily indicate the economic well-being of a country since activities that are detrimental to the long-term economy (like deforestation, strip mining, over-fishing, murders, terrorism) increase today’s GDP.

What does GDP tell us about the economy?
GDP measures the total market value (gross) of all U.S. (domestic) goods and services produced (product) in a given year. When compared with prior periods, GDP tells us whether the economy is expanding by producing more goods and services, or contracting due to less output.
