In this paper, we develop a network perspective on the welfare gains from trade in today's internationally fragmented supply chains. Towards this end, we study a Ricardian trade model featuring trade in final and intermediate products, and introduce a novel comparative statics approach to...

Many modern trade and growth models are characterized by multiple equilibria. In theory the analysis of multiple equilibria is possible, but in practice it is difficult to test for the presence of multiple equilibria. Based on the methodology developed by Davis and Weinstein (2004) for the case...

Iceberg transport costs are one of the main ingredients of modern trade and economic geography models: transport costs are modelled by assuming that a fraction of the goods shipped "melts in transit". In this paper, we investigate whether the iceberg assumption applies to the costs of...

China has used two main spatial policies to shape its geographic patterns of development: restricted labor mobility through the Hukou residential registration system and massive infrastructure investment, notably a 96,000 kilometer national expressway network. This paper develops a structural...

Sub-Saharan Africa's (SSA) physical geography is often blamed for its poor economic performance. A country's geographical location does, however, not only determine its agricultural conditions or disease environment. It also pins down a country's relative position vis-à-vis other countries,...

A variety of approaches to delineate metropolitan areas have been developed. Systematic comparisons of these approaches in terms of the urban landscape that they generate are however few. Our paper aims to fill this gap. We focus on Indonesia and make use of the availability of data on commuting...

Motorbike-based ride-hailing services are widespread in many of the most congested cities in the developing world. These services often predate the construction of modern public mass rapid transit systems. Ride-hailing services may complement such investments by providing important first and...

This paper examines the structure and dynamics of the global network of inter-firm research and development (R&D) partnerships using longitudinal data for 1989--2002. We contribute to a recent literature that has attributed patterns and changes in the network to major political and technological...
