We review a recent body of theoretical literature that links the creation and diffusion of knowledge and technology to openness. We analyze two channels through which the spread of new ideas occurs: international trade and the activity of multinational firms (multinational production). The...

This paper studies the life-cycle dynamics of exporters and multinational enterprises (MNEs). Using rich firm-level data, we document a comprehensive set of facts on entry, exit, and growth of new exporters and new MNEs. Guided by these facts, we build a model based on the standard...

Using firm-level data, we document two new facts regarding intrafirm trade and the activities of the foreign affiliates of U.S. multinational corporations. First, intrafirm trade is concentrated among a small number of large affiliates within large multinational corporations; the median...

The decline in the costs of multinational production (MP) has led some countries to specialize in innovation and others to specialize in production. To study the aggregate and distributional implications of this phenomenon, we develop a quantifiable general equilibrium model of trade and MP....
