Question

when does national factor income from abroad become negative​

Answer 1

The net foreign factor income (NFFI) is the difference between a nation’s gross national product (GNP) and gross domestic product (GDP). Net foreign factor income (NFFI) is the difference between the aggregate amount that a country’s citizens and companies earn abroad, and the aggregate amount that foreign citizens and overseas companies earn in that country. In mathematical terms, NFFI = GNP - GDP.

Answer 2

Answer:

NDP would exceed NNP in case the Net Factor Income from Abroad are negative. That is, the factor payments to abroad are more than factor payments received from abroad.
