Suppose a consumer purchased a new television for $1000 2 years ago. Today, that person sold it in her garage sale for $200. How does this affect the current GDP.
It will not affect the current GDP at all. GDP is a measure of all newly produced goods and services during a year, so 2 years ago the TV's full value would have been included in the GDP, but the sale of the TV as a used good later on would not be counted.
