This paper examines the home market effect in the framework of heterogeneous firms. The paper finds that not only trade costs but also fixed trade costs cause the home market effect and the reverse home market effect can occur as the fixed trade costs are very low. In addition, the magnitude of...

We derive a simple equation for the welfare gains from trade when tariffs are liberalized or iceberg trade costs fall. Covering various one-sector trade models that may or may not feature extensive margins and imperfect competition, we generalize the analysis of Arkolakis, Costinot and...

I show that military spending contributes to international arms proliferation through a push effect: large demand encourages production growth in the domestic market if transport costs are non-negligible. Under increasing returns to scale, the country can then supply weapons on the global market...

Does international trade affect the growth of cities, and vice versa? Assembling disaggregate data for four countries, we document a novel stylized fact: Export activity is disproportionately concentrated in larger cities - even more so than overall economic activity. We rationalize this fact by...

Zusammenfassung Die wichtigsten Merkmale der Schwarzmeerregion, die eine hohe Relevanz für die wirtschaftliche Entwicklungsstrategie haben, können wie folgt zusammengefasst werden Extreme Heterogenität und verbreitete Armut drei kleine Länder (Armenien, Georgien, Moldau), drei große Länder...

This issue of the Journal is devoted to physical integration in Latin America. The Editorial Committee set about designing the contents with a call for papers, which suggested topics and questions that focused on the subject while covering a broad spectrum. Regional physical integration is...

This paper presents a framework for estimating and simulating a quantitative spatial model of trade and violence. In this new theoretical and empirical setup, designed for the analysis of bilateral flows, we first model the general equilibrium interactions between the economic and fighting...

This paper describes the implementation in GAMS of an economic equilibrium model based on the GTAP version 9 dataset. We call this model and the ancillary programming tools GTAPINGAMS, version 9. Relative to previous installments of GTAPINGAMS, an innovation in this model is that it can easily...

Recent quantitative trade models treat import tariffs as pure cost shifters so that their effects are similar to iceberg trade costs. We introduce revenue-generating import tariffs, which act as demand shifters, into the framework of Arkolakis, Costinot and Rodriguez-Clare (2012), and generalize...
