The Bank of Papua New Guinea's Quarterly Economic Bulletin showed that PNG's GDP in 2022 was K100 billion. And if the net factor payment abroad was -K60 (negative K60 billion), calculate PNG's 2022 Gross National Product (GNP).
Gross National Product (GNP) is calculated as GDP + net factor payments from abroad.
GNP = GDP + net factor payment abroad
GNP = K100 billion + (-K60 billion)
GNP = K40 billion
Therefore, Papua New Guinea's Gross National Product (GNP) for 2022 was K40 billion.
