Similar results are obtained using our overall multimodal transport connectivity
indicator. The impact of multimodal transport on trade flows is positive and highly
statistically significant. A one percentage point improvement in performance is
associated with a nearly 3% increase in exports as a unilateral impact, and before
accounting for reallocation effects across economies. This effect is stronger than for
any of the component indices on their own. When the possibility of a ―virtuous cycle‖
between multimodal performance is accounted for, the effect is weaker but still
statistically significant
