Clarifying Trade Costs in Maritime Transport Jane Korinek OECD Trade and Agriculture Working Party on International Trade in Goods and Trade in Services Statistics 4-6 October 2010
Maritime transport costs : data collection • Values and volumes at HS-6 level • Transport costs: Ad valorem and $/T • Comprehensive customs data for Argentina, Australia, Brazil, Bolivia, Chile, Colombia, Ecuador, New Zealand, Paraguay, Peru, United States and Uruguay • Partial, estimated data for 32 additional countries including China, EU, Japan, Mexico, Russia • Permits calculation of • transport cost per tonne of merchandise • ad valorem equivalent
Customs data: complete • Where available, we use aggregate transport costs at HS-6 level in conjunction with trade values and volumes • Data issue: combining value and volume data • Classification issue: different classifications (HS-88 ; HS-96 ; HS-02) have been converted
Non-comprehensive data for remaining countries • Transport of grains in bulk: $/T. Source: Int’l Grains Council • Baltic Dry Index for industrial raw materials transported in bulk • Price per container used to estimate some data using a methodology of relative prices (sources: UNCTAD/Containerisation Intl or Drewery)
Data issues As with all data sets there are issues, some outstanding and some resolved • Estimated data: aggregate to disagreggated ; BDI is transport costs per shipload of material • Combining value and volume data • Cut-off point : we removed 2% of the data points • Classification conversion
Evolution of maritime transport costs in developing and OECD countries
From analytical work on determinants of Transport Costs: Trade Imbalance
Impact of MTC on trade in agriculture • A doubling of transport costs ($/T) is associated with a 33-36 % decline in agricultural trade overall • Distance is still significant • The impact of transport costs on trade is increasing over time – by 1.5 percentage points per year
