摘要：The cotton basis is examined graphically and statistically to determine if the basis differs across U.S. production regions and within the crop year as economic theory predicts. The analysis indicates the basis differs for some, but not all, regions consistent with the theory. Results also show that the typical seasonal pattern is not apparent for regions which export most of their cotton, most likely because demand in these regions is seasonal.
