Answer:
Gross National Product (GNP) includes the value of all goods and services produced by nationals both inside the U.S. and abroad. For example, GNP includes goods produced by American manufacturers in Mexico-
Gross Domestic Product (GDP) includes only the value of all goods and services produced domestically, that is, within the country, whether by national firms or foreign firms. For example, GDP includes goods produced by Swiss manufacturer Nestlé in their American Plants.
Taking this into account, we can see that a situation which would make GNP much larger than GDP is if there are many more American firms producing aborad than foreign firms producing within the country. In this circumstance, American production abroad would inflate GNP, while the small foreign production in America would not increase GDP as much.
