WTO Warns Against the Cumulative Negative Impact of Trade Restrictions

“The danger today is of an incremental build-up of restrictions that could slowly strangle international trade and undercut the effectiveness of policies to boost aggregate demand and restore sustained growth globally,” the WTO said, according to the FT. While the WTO reported “no indication of an imminent descent into high intensity protectionism,” it did note that the adoption of protectionist measures by member nations increased by 25% in 2008. It cited measures to restrict footwear imports, discourage steel imports and provide government aid to domestic auto industries.

Wharton Faculty Also Express Concerns Over U.S. Trade Restrictions

Kobrin told Knowledge at Wharton that history points to an urgent need to defend free trade. “It’s critical. It’s pretty clear that protectionism exacerbated the Depression last time, and [economies] are more integrated now.”
