Supply of American goods: This term refers to the quantity of American goods available in the market. It depends on factors such as production capacity, input costs, and government regulations.
Substitute goods: Substitute goods are alternative products that can be used in place of each other. For example, if the demand for American cars increases, the demand for foreign cars may decrease as people switch to buying American cars instead.
Complementary goods: Complementary goods are products that are consumed together or used together with another product. For example, an increase in the demand for American smartphones may also lead to an increase in the demand for phone accessories like cases or chargers.
