Since the outbreak of the COVID-19 pandemic there has been a discussion among researchers and policy makers about changes to global value chains, both about expected changes and changes that should be promoted by government policies. In this paper we conduct an in-depth analysis of the reasons...

The rapid rise in global fragmentation - foreign investment, global supply chains, and 'production sharing' - is fundamentally reshaping the multilateral trading system. This paper uses a simple economic modeling framework to understand how the global fragmentation phenomenon may reshape the...

To what extent must nations cede control over their economic and social policies if global efficiency is to be achieved in an interdependent world? This question is at the center of the debate over the future role of GATT (and its successor, the WTO) in the realm of labor and environmental...

The Marrakesh Agreement establishing the WTO recognizes the need for positive efforts designed to ensure that developing countries and especially the least developed among them secure a share in the growth in international trade commensurate with the needs of their economic development.This...

Disruptions to global value chains (GVCs) - caused by conflicts, natural disasters, and accidents that close transport routes - and that affect specific regions or sectors, are not unusual. However, in recent years and amid the Covid-19 pandemic, they have become more frequent and severe. High...

The trade linked to international production networks - supply-chain trade for short - is associated with momentous global economic changes. This paper presents a portrait of the global pattern of supply-chain trade and how it has evolved since 1995. The paper draws on a variety of data sources...

Specialization alters the incidence of manufacturing trade costs to buyers and sellers, with pro-and anti-globalizing effects on 76 countries from 1990-2002. The structural gravity model yields measures of Constructed Home Bias (the ratio of predicted local trade to predicted frictionless local...

We study the implications of global supply chains for the design of monetary policy, using a small-open economy New Keynesian model with multiple stages of production. Within the family of simple monetary policy rules with commitment, a rule that targets separate producer price inflation at...

This paper develops a multi-stage general-equilibrium model of global value chains (GVCs) and studies the specialization of countries within GVCs in a world with barriers to international trade. With costly trade, the optimal location of production of a given stage in a GVC is not only a...

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...
