The article examines the potential benefits for the United States from joining the Trans-Pacific Partnership (TPP). The researchers look at how this trade agreement, involving 12 countries, could impact U.S. trade since a significant portion of it already falls under NAFTA with Canada and Mexico. They focus on areas within the TPP that could lead to greater trade opportunities for U.S. businesses and consumers. By analyzing the potential for increased liberalization in specific sectors, the researchers aim to identify where the U.S. might see the most gains from the TPP.
