China's Hukou system poses severe restrictions on labor mobility. This paper assesses the consequences of relaxing these restrictions for China's internal economic geography. We base our analysis on a new economic geography model. First, we obtain estimates of the important model parameters on...

The physical or absolute geography of Sub-Saharan Africa (SSA) is often blamed for its poor economic performance. A country's location however not only determines its absolute geography, it also pins down its relative position on the globe vis-à-vis other countries. This paper assesses the...

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...

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...

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...
