The study looked at how changes in trading rules could affect EU agriculture. They used computer simulations to see what would happen if the EU reduced its tariffs more than other countries. Results show that this could lead to less trade within the EU but more trade with other countries. However, these changes might hurt newer EU countries' ability to sell certain products like meat and dairy. While the EU as a whole could benefit, the gains would not be spread evenly among all member countries, with older EU countries expected to improve more than newer ones who could face some difficulties.
