這個多邊貿易機構承認成員國政府除自由貿易之外還具有制定國內政策的權利。

The multilateral trading system recognizes that governments have legitimate aims other than free trades.

這些措施的代價（對于消費者來說商品價格較高，選擇性較小）比較容易衡量；代價一般高于收益（更高的公司利潤和政府關稅收入）。

The costs of such measures (higher prices and less choice for consumers) are reasonably easy to quantify; they typically outweigh the benefits (fatter company profits and tariff revenues for governments).

事實上這些爭端的一些新的參與者，比如說保護消費者權利活動者和環保團體，不大會受經濟因素的影響。

Indeed some of the new actors in such disputes, such as consumer-rights activists and environmental groups, may not be susceptible to economic reasoning.
