To determine who would contribute to the GDP of the United States, we need to consider where the production takes place, as GDP measures the value of all final goods and services produced within a country's borders, regardless of the nationality of the producer.
Let's evaluate each option:
a. A U.S. citizen producing goods in Portugal - Does not contribute to U.S. GDP, as the production occurs outside the U.S.
b. A citizen of Japan producing goods in the United States - Does contribute to U.S. GDP, as the production occurs within U.S. borders.
c. A U.S. citizen producing goods in the United States - Does contribute to U.S. GDP, as the production occurs within U.S. borders.
d. A citizen of Spain producing goods in Brazil - Does not contribute to U.S. GDP, as the production occurs outside the U.S.
e. A U.S. citizen producing goods in Canada - Does not contribute to U.S. GDP, as the production occurs outside the U.S.
Therefore, the people who would contribute to the GDP of the United States are:
- b (a citizen of Japan producing goods in the United States)
- c (a U.S. citizen producing goods in the United States)
