The World is Not Yet Flat
The paper provides evidence of the effects of changes in transport costs on the geographic concentration of industries. The analysis uses micro-level commodity flow data and micro-geographic plant-level data to construct industry-specific ad valorem trucking rates and continuous measures of geographic concentration. The findings show that, controlling for international trade exposure and input-output links, increasing trucking rates are significantly associated with declining geographic concentration. The effect is large: changes in trucking rates explain around 20 percent of the observed decline in geographic concentration of Canadian manufacturing industries between 1992 and 2008.

| Summary: | The paper provides evidence of the
effects of changes in transport costs on the geographic
concentration of industries. The analysis uses micro-level
commodity flow data and micro-geographic plant-level data to
construct industry-specific ad valorem trucking rates and
continuous measures of geographic concentration. The
findings show that, controlling for international trade
exposure and input-output links, increasing trucking rates
are significantly associated with declining geographic
concentration. The effect is large: changes in trucking
rates explain around 20 percent of the observed decline in
geographic concentration of Canadian manufacturing
industries between 1992 and 2008. |
