Answer 1

Answer:

Alas, nothing is perfect. And GDP is no exception. As much as economists like to use GDP as a measure of output, or even as a measure of a country’s well being, GDP has some limitations when trying to answer those questions. GDP leaves out some production in an economy, such as the squash your mom might grow in the backyard, or other non-marketed goods. Even though GDP is frequently used to capture the wellbeing of a society, it was never intended to do that, and as a result it leaves out important aspects of well-being like pollution or even happiness.
