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 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...

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...

Using a novel common econometric specification, we examine the measurement of three important effects in international trade that historically have been addressed largely separately: the (partial) effects on trade of economic integration agreements, national borders, and bilateral distance....

Standard trade theory suggests that Free Trade Agreements (FTAs) could disrupt trade between members and non-members. However, the trade diversion effects of FTAs have not been thoroughly examined empirically. Using a novel empirical approach, we confirm that FTAs that entered into force...

Despite ample anecdotal evidence for intensive international integration, the gravity literature of international trade fails to deliver consistent empirical support for globalization and for diminishing effects of distance on bilateral trade. Capitalizing on the properties of the structural...

We use a novel data set with verified observations of trade-induced layoffs by U.S. firms to study the interaction between firm productivity and trade liberalization as key determinants of firm-level job destruction due to trade. We find that patterns of trade-induced layoffs are broadly...
