Often, the incremental growth that comes with a trade opening is unevenly shared; moreover, in many cases, some receive a smaller share than they did before. Here is where government must intervene using its traditional tools, taxation and redistribution, as well as complementary policies such as social safety nets and adjustment assistance.
