4. Briefly explain what is meant by the term "potential GDP," and identify the alternative term that is considered to be synonymous from a macroeconomic perspective with "potential GDP." Potential GDP is defined as the maximum quantity that an economy can produce given its existing levels of labor, physical capital, and technology, in the context of its existing market and legal institutions. Potential GDP is also called full-employment GDP.
