Michael R. Wessel, former commissioner of the U.S. Trade Deficit Review Commission, said in May 2015 that exempt consultants like him were “prohibited from “publicly sharing our criticisms of certain proposals and approaches.” He claimed that only parts of the text had been provided “to be read under the watchful eye of a USTR official,” that access to a secure government-run website did not contain the most up-to-date information, and that in order for exempt consultants to obtain that information, he “had to go to and register with certain government entities, to read the documents” and “even then, the administration determines what we can and cannot verify, and often provides carefully edited summaries instead of the actual underlying text, which is crucial to truly understanding the consequences of the agreement.  Harvard economist Robert Z. Lawrence says that the model used by the Tufts researchers “is simply not capable of credibly predicting the effects of TPP,” arguing that the model used by Petri and Plummer is superior.  Lawrence argues that the model used by the Tufts researchers “does not have the granularity that allows it to estimate variables such as exports, imports, foreign direct investment, and changes in industrial structure. As a result, its predictions ignore the benefits to TPP economies resulting from increased specialization, economies of scale, and better consumer choice.  Lawrence also notes that the model used by the Tufts researchers notes that the TPP will lead to a 5.24% drop in GDP in non-TPP developing countries such as China, India and Indonesia, which Lawrence is very skeptical about: “It is not credible that a trade deal of this magnitude can plunge the rest of the world into recession.”  Harvard economist Dani Rodrik, a well-known skeptic of globalization, says that Tufts researchers “do a poor job of explaining how their model works, and the details of their simulation are somewhat bleak. the Capaldo framework lacks sectoral and country-specific details; its behavioural assumptions remain opaque; and its extreme Keynesian assumptions do not fit well with its medium-term perspective.  What became the TPP was motivated by a 2005 trade agreement between a small group of Pacific Rim countries, including Brunei, Chile, New Zealand and Singapore. In 2008, President George W. Bush announced that the United States would begin trade negotiations with this group, prompting Australia, Vietnam and Peru to join.
During the talks, the group expanded to include Canada, Japan, Malaysia and Mexico – a total of twelve countries. This partnership creates a level playing field for our farmers, ranchers and manufacturers by eliminating more than 18,000 taxes that different countries impose on our products. It contains the strongest labour and environmental commitments of any trade agreement in history, and these commitments are enforceable, unlike previous agreements. It promotes a free and open Internet. It strengthens our strategic ties with our partners and allies in a region that will be crucial for the 21st century. It is an agreement that puts American workers first and will help middle-class families move forward. Fredrik Erixon and Matthias Bauer of the European Centre for International Political Economy (ECIPE) write that Tufts` analysis has such serious flaws “that its results should not be considered reliable or realistic.”  You write that the Tufts model “is on the whole a demand-driven model that makes no effort to capture the supply-side effects of trade, which are the effects that have proven to be the positive fundamental effects of trade liberalization. Equally problematic is that the model is not designed to assess the impact of trade agreements on trade – in fact, the model is profoundly unsuitable for such an exercise. No trade economist, regardless of his school of thought, has ever used this model to make estimates of trade.
The reason for this is simple: if a model cannot predict the impact of trade liberalization on trade flows and the pattern of trade, it is useless at all.  They add: “According to Capaldo`s analysis, structural change and the emergence of new industries play no role. Capaldo implicitly assumes that an economy with its labor and capital does not respond to new circumstances and does not adapt. New competition only leads to new unemployment. In addition, the impact of reducing barriers to international trade on product and process innovations is overlooked. Finally, Capaldo does not take into account the effects of competition on production costs and final consumer prices.  But what should the TPP be used for? And does it have a future without the United States? South Korea did not participate in the 2006 agreement, but expressed interest in joining the TPP and was invited by the United States to the TPP rounds of negotiations in December 2010. following the successful conclusion of the Free Trade Agreement between the United States of America and the Republic of Korea.  South Korea had already concluded bilateral trade agreements with some TPP members, but areas such as vehicle manufacturing and agriculture had yet to be agreed, making it a little more complicated to continue multilateral negotiations on the TPP.  South Korea could join the TPP as part of a second wave of expansion of the trade agreement.  The Obama administration reportedly lobbied for language that requires all countries to introduce a similar 12-year requirement.
This was surprising because Obama`s own 2016 budget proposed shortening the exclusivity period to seven years. In the end, the U.S. negotiators did not get what they wanted; The final text of the TPP requires countries to provide five to eight years of data exclusivity for biologic drugs. Progress in the Trans-Pacific Partnership talks was reflected in the 14th round of TPP negotiations, which took place on September 15. September 2012 in Leesburg, USA, completed, continued. TPP negotiators met in November. .
