2.GNP is the gross national product. We add the factor income (wages, profits and rents) obtained from other countries and subtract the factor income paid to other countries in the world: GNP=GDP+ factor income from abroad-GDP paid to foreign factors measures the total income of domestic production, and GNP measures the total income obtained by nationals (residents of a country). For example, if a Japanese resident owns an apartment building in new york, the rental income he earns is part of the GDP of the United States, because this income is earned in the United States. However, this kind of rental income is not a part of GNP in the United States because it is an element of payment to foreign countries.
