The correct option is 2 and 3 only.
Explanation
Foreign trade functions as a primary mechanism for the "Integration of Markets." It links domestic markets with global markets, allowing the free flow of goods, services, and capital, thereby creating a unified global economic space.
Statement 1 is Incorrect:
Integration of markets through foreign trade does not restrict producers; rather, it expands their reach. It allows producers to sell their goods not only in domestic markets but also to compete in markets located in other countries. It removes the constraints of local demand.
Statement 2 is Correct:
Foreign trade provides an opportunity for producers to reach beyond domestic boundaries. It enables access to a larger consumer base and allows for specialization based on comparative advantage, facilitating global market participation.
Statement 3 is Correct:
As markets integrate, goods travel freely between them. This competition and flow of goods tend to equalize the prices of similar goods across different markets (a concept known as price convergence or the Law of One Price). If prices differ, arbitrage opportunities arise, eventually bringing prices closer together.
Key Takeaway:
Foreign trade integrates markets by expanding the scope for producers beyond national borders, increasing consumer choice, and driving the convergence of prices for similar goods across different geographies.
