We provide evidence for the effects of changes in transport costs, international trade exposure, and input-output linkages on the geographical concentration of Canadian manufacturing industries. Increasing transport costs, stronger import competition, and the spreading out of upstream suppliers...

There is a large consensus among international institutions and national governments to favor urban-containment policies - the compact city - as a way to improve the ecological performance of the urban system. This approach overlooks a fundamental fact: what matters for the ecological outcome of...

We estimate the effect of interstate highways on the level and composition of trade for us cities. Highways within cities have a large effect on the weight of city exports with an elasticity of approximately 0.5. We find little effect of highways on the total value of exports. Consistent with...

This paper reports panel gravity estimates of aggregate bilateral trade for 130 countries over the period 1962-96 in which the coefficient of distance is allowed to change over time. In a standard specification, in which transport costs are proxied only, it is found paradoxically that the...

This Paper first develops a tractable economic geography model we use to investigate the decline of transport costs as a cause of regional inequalities. Next, we perform a structural estimation of this model using a new dataset on road transport costs between the 341 French Employment Areas. We...

This Paper uses bilateral trade data for OECD countries at the 3-digit industry level to investigate the geography of intra-industry trade (IIT). IIT diminishes with distance and much of the existing empirical literature suggests that this is an inherent characteristic of such trade, arguing...

This Paper develops a methodology to compute transport costs at low infra-country geographical levels. This simultaneously accounts for the real network infrastructure, a distance cost (fuel, repair, tolls), and a time opportunity cost (wages, insurance and general charges, vehicle use). When...

This paper examines if international trade can reduce total welfare in an international oligopoly with differentiated goods. We show that welfare is a U-shaped function in the transport cost as long as trade occurs in equilibrium. With a Cournot duopoly trade can reduce welfare compared to...

We consider an economic geography model in which all firms and workers are mobile, but the agglomeration of firms and workers within a region generates urban costs. We show that industries with high transport costs tend to be more agglomerated than industries with low transport costs. This is to...

We study the effects of a decrease in trade costs on the spatial distribution of industry in a multi-regional economy, when a rise in the regional population of workers generates higher urban costs. When the number of cities is unaffected by falling trade costs, small cities become smaller for...
