A significant piece of the answer can be glimpsed in a recent report by U.S. Trade Representative Ron Kirk. In a press statement about the Generalized System of Preferences, a series of trade preferences for developing countries, Kirk said: "GSP is a valuable tool for advancing the administration's goals to boost trade and to advance international economic development. The GSP program helps developing countries to grow their economies while also helping U.S. businesses, workers and consumers by lowering the costs of imported goods, including those used as inputs for U.S. manufacturing. The annual review allows the administration to ensure that the program is working as intended."
