Is the International Border Effect Larger than the Domestic Border Effect? Evidence from U.S. Trade (2009, background): “5 As discussed by Hummels (2007), transportation cost patterns are in fact highly complex.”
The empirics of new economic geography (2010, neutral): “Although some detailed evidence is available for transportation costs (see, in particular, Limao and Venables, 2001; Hummels, 2007), there is a scarcity of evidence on other trade frictions such as information and communication costs.”
Structural gravity equations with intensive and extensive margins (2010, neutral): “Glaeser and Kohlhase’s (2003) estimate of the same parameter is 0.3, and Hummels’ (2007) average estimate is 0.2.”
Gravity, trade integration, and heterogeneity across industries (2011, background): “…a few components, for instance transportation and insurance costs, usually proxied by the ratio of c.i.f. and f.o.b. trade values (Harrigan, 1993, Hummels, 2001a, 2007), policy barriers such as speci…c tari¤ or non-tari¤ barriers (Chen, 2004, Harrigan, 1993, Head and Mayer, 2000), informational…”
In Search of the Armington Elasticity (2014, positive): “We jointly estimate the macro equation (40) together with equation (30) to obtain the macro elasticity, making use of the cross-equation restriction ρ2g = ρ1g/ρ F in (38) and using estimates of the micro elasticities and ρ1g that come from (25).”
Towards a Theory of Trade Finance (2011, background): “Hummels (2001) discusses the effect of physical transport time while Djankov, Freund, and Pham (2006) analyze the effect of time delay from the factory gate to the means of transportation on international trade.”
Estimating the Effects of the Container Revolution on World Trade (2013, neutral): “9 In his survey of how changes in transportation costs have affected international trade in the post world War II period, Hummels (2007) has detected an actual increase in ocean shipping rates during 1974-84, a period after the adoption of containerization in the US.”
Transport Policies and Development (2015, background): “Long commuting times may also be detrimental to employment growth, as demonstrated by Hymel (2009) who estimates the causal impact of traffic congestion on aggregate employment growth in US metropolitan areas.”
Trade and Income—Exploiting Time Series in Geography (2019, methodology): “Bilateral great circle distances (the measure of air distance) are from the CEPII.9 The CEPII provide a number of different variations on the great circle distance described in more detail in Head and Mayer (2002).”
Trade Booms, Trade Busts, and Trade Costs (2011, background): “Or perhaps, it could be located in the substantial drops—but subsequent flatlining—in both air and maritime transport charges up to the first oil shock documented in Hummels (2007).”
