What is the country similarity theory? According to this theory, what factors affect trade patterns?
Answer: Observations of trade patterns reveal that most of the world's trade occurs among countries that have similar characteristics, specifically among industrial, or developed, countries. The country similarity theory says that once a company has developed a new product in response to observed market conditions in the home market, it will turn to markets it sees as most similar to those at home. In addition, markets in industrial countries can support products and their variations. Thus, companies from different countries produce different product models, and each may gain some markets abroad.
