We extend the structural gravity model to identify external economies or diseconomies of scale elasticities of cross-border trade. We find statistically and quantitatively significant economies of scale in cross-border trade in 5/8ths of sector-direction cases for Canadian provinces while the...

We develop a structural gravity model that introduces scale effects in bilateral trade. Scale effects and incomplete passthrough give two channels through which exchange rates have real effects on trade patterns. Estimates from Canadian provincial trade data identify these effects through their...

We estimate geographic barriers to trade in nine service categories for Canada's provinces from 1997 to 2007 with novel high quality bilateral provincial trade data. The border directly reduces average provincial trade with the US relative to interprovincial trade to 2.4% of its borderless...

This paper infers the terms of trade effects of the Free Trade Agreements (FTAs) of the 1990s. Using panel data methods to resolve two way causality between trade and FTAs, we estimate large FTA effects on bilateral trade volume in digit manufacturing goods from 1990-2002. We deduce the terms of...

We develop and apply a procedure to flexibly estimate intra-national border barriers and intra-regional trade costs. Bilateral border barriers very significantly depress Canadian inter-provincial trade for some pairs, though the overall effect is rather small. Bilateral distance imposes much...

This paper provides striking confirmation of the restrictions of the structural gravity model of trade. Structural forces predicted by theory explain 95% of the variation of the fixed effects used to control for them in the recent gravity literature, fixed effects that in principle could reflect...

Neglected properties of the structural gravity model offer a theoretically consistent method to calculate the incidence of estimated trade costs, disaggregated by commodity and region, and re-aggregated into forms useful for economic geography. For Canada's provinces, 1992-2003, incidence is on...

This paper infers the terms of trade effects of Free Trade Agreements (FTAs) with the structural gravity model. Using panel data methods to resolve two way causality between trade and FTAs, we estimate direct FTA effects on bilateral trade volume in 2 digit manufacturing goods from 1990-2002. We...

We propose a short-run theory of the extensive margins of trade, comprising the standard international extensive margin and a novel domestic extensive margin. The domestic extensive margin allows identification of globalization and specific policy effects not properly identified in previous...
