Abstract
Congress prepares to take up the Trans-Pacific Partnership (TPP), the debate is reviving old misunderstandings about how trade agreements affect the US and other economies. Over the past four years, colleagues and I have built models of the TPP that are now frequently mentioned in the debate.1 Since this work is likely to provide the most detailed assessment of the TPP until the United States International Trade Commission (USITC) issues its report some months from now, our results and their limitations need to be clear.
