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...

Economists interested in location choices usually focus their attention on investments abroad. This neglects the fact that multinational enterprises continue to invest domestically while undertaking foreign expansion. This paper compares investments at home and abroad. Our firm-level dataset...

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...

As production comes to depend more on intangible productive assets, the location of production by multinational firms becomes increasingly ambiguous. The reason is that, within the firm, these assets have no clear geographical location, but only a nominal location determined by the firm's tax or...

We develop a simple information-based model of FDI flows. On the one hand, the abundance of intangible' capital in specialized industries in the source countries, which presumably generates expertise in screening investment projects in the host countries, enhances FDI flows. On the other hand,...

The literature has shown that the implied welfare gains from international financial integration are very small. We revisit the existing findings and document that welfare gains can be substantial if capital goods are not perfect substitutes. We use a model of optimal savings that includes a...

We explore the relation between international financial integration and the level of entrepreneurial activity in a country. We use a unique firm level data set of approximately 24 million firms in nearly 100 countries in 2004 and 1999, which enables us to present both cross-country and industry...

Standard theoretical arguments tell us that countries with relatively little capital benefit from financial integration as foreign capital flows in and speeds up the process of convergence. We show in a calibrated neoclassical model that conventionally measured welfare gains from this type of...
