The effects of geography and productivity on the global pattern of production are captured here in a specific factors gravity model. Simple enough for sharp results, the model is yet rich enough to contain the high dimensional productivity frictions in production and distribution of a many...

Countries that are more engaged in production sharing exhibit higher bilateral manufacturing output correlations. We use data on trade flows between US multinationals and their affiliates as well as trade between the United States and Mexican maquiladoras to measure production-sharing trade and...

Time is money, and distance matters. We model the interaction of these truisms, and show the implications for global specialization and trade: products where timely delivery is important will be produced near the source of final demand, where wages will be higher as a result. In the model,...

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...

The existence of a natural resource curse has been a longstanding theme in the economic literature and in policy discussions. We propose an alternative mechanism and study its policy implications. The mechanism is based on the interaction between two building blocks: specialization in...

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...

This paper explores the emergence of a world economy since 1950 and its implications for the world's labor force. There are four main sets of conclusions. First, although the integration of national economies since 1950 has been considerable, the world economy is still in its adolescence. Rapid...

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...

We model the implications of the classical ideas that larger markets allow for a finer division of labor and this division feeds back into larger market size. Market size affects specialization due to firm-level increasing returns to scale arising from fixed costs of adopting...
