The procedures and practices to implement the provisions relating to tariff negotiations and renegotiations have evolved considerably since the GATT was established in 1947. The provisions themselves have undergone some changes in the last fifty-four years. Professor Hoda reviews the evolution of these provisions and of the procedures adopted and practices followed by the contracting parties to GATT 1947 and the Members of the WTO. He goes on to offer some conclusions and recommendations. This new book will be of particular interest to negotiators including Geneva based delegations, members of government trade ministries, economists, and all academics who specialise in trade policy.
