This paper provides a general and unified framework to study the role of production networks in international GDP comovement. We first derive an additive decomposition of bilateral GDP comovement into components capturing shock transmission and shock correlation. We quantify this decomposition...

Many of the exports of developing countries are channeled through global value chains (GVCs), which also act as conduits for new technologies. However, new capabilities and productive employment remain limited so far to a tiny sliver of globally integrated firms. GVCs and new technologies...

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...

Growth in international trade and globalization has been correlated in nearly all countries with a worsening of the less skilled labor situation relative to the skilled. In this empirical paper, I show that an important component of recent globalization in France has been a huge growth in...

We argue that trade in intermediate inputs, or 'global production sharing,' is a potentially important explanation for the increase in the wage gap between skilled and unskilled workers in the U.S. and elsewhere. Using a simple model of heterogeneous activities within an industry, we show that...

This paper examines the home country bias in the goods market among OECD countries. An average country imports about two and a half times as much from itself as from an otherwise identical foreign country, after controlling for sizes of exporter and importer, their direct distance, geographic...

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....

After decades of rising global economic integration, the world economy is now fragmenting. To measure this phenomenon, we introduce an index of geopolitical fragmentation derived from various empirical indicators. This index is developed using a flexible dynamic factor model with time-varying...

This paper proposes a framework for gross exports accounting that breaks up a country's gross exports into various value-added components by source and additional double counted terms. By identifying which parts of the official trade data are double counted and the sources of the double...

Revolutionary transformations of industry and trade occurred from 1985 to the late-1990s - the regionalisation of supply chains. Before 1985, successful industrialisation meant building a domestic supply chain. Today, industrialisers join supply chains and grow rapidly because offshored...
