"The principle of free trade is under attack in the United States. Yet, there is no consensus on the precise role of trade in affecting American incomes. Important questions remain. To what extent is trade responsible for growing income inequality in the United States (and elsewhere), and can policymakers alleviate the ill effects of free trade while still reaping the benefits of open markets?". "This book joins the debate with a robust defense of the principle and practice of free trade in the United States."--BOOK JACKET.
