As with many trade agreements, the TPP negotiations were conducted in a very secret until the conclusion. Draft agreements were kept secret during the negotiations and access to the working text was severely restricted, even for government officials and representatives of the companies involved in the discussions.  However, some sections of TPP projects were leaked to the public by WikiLeaks, which published a draft chapter on intellectual property in 2013 an environmental chapter project in 2014 and the last chapter on intellectual property in 2014.  Fredrik Erixon and Matthias Bauer of the European Centre for International Political Economy (ECIPE) write that Tufts` analysis is so flawed « that their results should not be considered reliable or realistic. »  You write that the tufts model « is, on the whole, a demand-driven model, which makes no effort to measure the effects of trade on supply, which are the effects that turn out to be the main positive effects of trade liberalization. What is also problematic is that the model is not designed to assess the impact of trade agreements on trade – in fact, the model is deeply unsuited to such an exercise. No commercial economist, regardless of the school of thought he or she possesses, has ever used this model to make trade estimates. The reason is simple: if a model cannot predict the impact of trade liberalization on trade flows and the profile of trade, it is useless.  They add: « In Capaldo`s analysis, structural changes and the emergence of new industries play no role. Capaldo implicitly assumes that an economy does not react with its work and capital and adapts to new circumstances. New competition only creates new unemployment.
In addition, the impact of barrier reduction on international trade on product and process innovation is overlooked. Finally, Capaldo does not take into account the impact of competition on production costs and prices to the end consumer.  New Zealand ratified the TPP on 11 May 2017.  Prime Minister Jacinda Ardern will attempt to renegotiate the Trans-Pacific Partnership (TPP) agreement in Vietnam in time so that the government can ban foreign speculators from buying existing New Zealand homes. She said, « We believe it will be possible to reconcile our desire to ensure that we provide affordable housing by easing demand and prohibiting foreign speculators from buying existing homes while meeting our business objectives. »  Brunei, Chile, Singapore and New Zealand are parties to the Trans-Pacific Strategic Economic Partnership Agreement (TPSEP), signed in 2005 and entered into force in 2006.
