ABSTRACT
From the discussions in the previous chapters, it must be clear to you by now that exchange of goods and services among economic agents is mutually beneficial to all, with neither side obliging the other. Interpersonal trade enhances society's welfare. This argument extends itself further. Interregional trade does the same. In India, Assam produces plenty of tea; Jharkhand has plenty of coal; hence, it is mutually beneficial to exchange. In the United States, about two-third of nuts is produced in California, whereas the major corn producers are the mid-western states like Iowa, Illinois, and Nebraska. Interregional trade in nuts and corn in the United States is a good thing.
