Final answer:
Pfeister Inc.'s production of glass doors in New York will be counted only in the U.S. GDP. GDP accounts for economic activities within a country's borders, and trade activities like exporting video cameras and importing televisions reflect country-specific specialization and skill sets.
Step-by-step explanation:
The output of glass doors by Pfeister Inc., a German manufacturer located in New York, will be counted in the U.S. GDP only. Gross Domestic Product (GDP) is a measure of the economic activity within a country's borders. Since Pfeister Inc. is producing the glass doors in New York, this contributes to the United States' economic activity, regardless of the origin of the company or the machinery used in production.
It's important to consider that international trade involves intra-industry trade where countries import and export similar types of goods, such as different varieties of machinery. For example, the U.S. might export machinery for wood manufacturing and import machinery for photographic processing. Countries often specialize in producing certain goods based on unique skills developed by their firms, rather than differences in general skill levels.
In essence, countries like Germany specialize in certain industries, exporting goods like video cameras, while importing others like televisions, and Poland might do the opposite. This specialization is driven by the country's unique set of capabilities and focuses.
