We carry out an indirect inference test of two versions of a computable general equilibrium (CGE) model of world trade. One of these, the 'classical' model,is well-known as the Heckscher-Ohlin-Samuelson model of world trade, in which countries trade homogeneous products in world markets and...

The recent literature on firm-to-firm trade has documented salient empirical regularities of the buyer-seller network. We propose a simplistic re-interpretation of the classical Krugman (1980) model that accounts for surprisingly many of the empirical regularities. This re-interpretation relies...

We develop a model of international trade with two sources of firm heterogeneity: "productivity" and "caliber". Productivity is modeled as is standard in the literature. Caliber is the ability to produce quality using few fixed inputs. While there is no quality restriction to sell domestically,...

We develop a model of international trade with export quality requirements and two dimensions of rm heterogeneity. In addition to \productivity", rms are also heterogeneous in their \caliber" { the ability to produce quality using fewer xed inputs. Compared to single-attribute models of rm...

In addition to "productivity", firms are also heterogeneous in their "caliber" {the ability to produce quality using fewer fixed inputs. Compared to singleattribute models of firm...

We develop a model of international trade with two dimensions of firm heterogeneity and export quality constraints that manifest as higher variable trade costs for lower quality firms. In addition to "productivity", firms are also heterogeneous in their "caliber" -- the ability to develop...

Perceptions of international trade barriers are important in the decision of firms to export.This study makes an empirical analysis of the perceptions with respect a particular sector. Two industrial hubs (locations) were chosen. The perceptions of the firms were very different in the two...

The purpose of this paper is to explain the relation between the Border Effect and industrial concentration. This is achieved by founding this relation on the Home Market Effect and testing the robustness of this foundation through an application to the European Single Market. A sectorial...
