The article explores how a trade agreement between Mexico and the U.S. could affect the U.S. economy. It looks at things like which areas might see more jobs, how different industries could be impacted, and the overall effect on the U.S. gross national product. The researchers believe that the agreement will have a small impact on the U.S. economy because it's already big and there's a lot of trade between the two countries. They also consider factors like environmental regulations and wage differences that could play a role. Overall, the study suggests that the trade agreement may not drastically change the U.S. economy, but it could have some effects on specific industries like agriculture, automobiles, and financial services.
