Raghuram Rajan is a former governor of the Reserve Bank of India. An opinion column on bloomberg.com quotes Rajan as stating the following about international trade: “It involves countries with very different income levels, allowing each to bring its comparative advantage to the production process.” Average incomes in the United States are more than nine times greater than in India. If incomes in the United States are so much higher than in India, how can the United States be made better off by trading with India? If incomes in India are so much lower than in the United States, how can India be made better off trading with the United States?
