Answer:
remains unchanged because it was counted when your parents earned it.
Explanation:
GDP is the total value of goods & services produced within an economy, during a period of time.
It can be recorded by following methods : Value Added (by each producer) , expenditure (by all consumers), income (of all producers) .
There are many precautions while calculating GDP : Gifts, Second Hand goods etc are not included in GDP. Such because these goods have not lead to any new flow of goods & services in economy, the transaction includes mere transfer of ownership. These goods & services had already been included in 'GDP' at time of purchase under expenditure or income method & need not be included at time of gift giving or second hand purchase. If included again, it leads to double counting.
Similarly : Parents surprise gift doesn't affect GDP as it has already been accommodated in it while parents had earned it.
