3. Andrew Bernard, J. Bradford Jensen, Stephen Redding, Peter Schott on Global firms: Insights for trade and trade policy
   

   Events of the last year have raised questions about the future growth of international trade. This column examines the role played by ‘global firms’ that both import and export, and are likely to be part of multinationals, in the international economy. In a world of interdependent firm decisions, small reductions in tariffs or trade costs can have magnified effects on trade flows, as they induce firms to serve more markets with more products at greater volumes, and also to source greater volumes of intermediate inputs from more countries.
