International transportation costs and the use of a country’s imports cif/fob ratios as a measure
for ad valorem shipping and direct international transportation costs measures has been at the
forefront of international transport costing debates. Many researchers and analysts use the
imports cif/fob ratios as a proxy for direct transportation costs in the absence of direct
measures.
The study was motivated to examine the authenticity and use of the imports cif/fob ratios as a
measure for international transport costs. The study highlights the impact of the use of the
ratios in presenting and interpreting international transportation costs.
The study examined, investigated and analysed data on the United States, Germany, South
Africa and Malawi and provided empirical evidence that the imports cif/fob ratios as a
measure for ad valorem shipping and international transport costs are distorted and misused
and are therefore misrepresentative and uninformative of the actual direct shipping and
international transport costs of countries. Evidence from the study shows severe limitations in using the imports cif/fob ratios, as the trade data used for devising them are largely unreliable
and inaccurate.
Users of the imports cif/fob ratios generally assume when using the ratios that, the
composition of imports are constant. By means of correlation analysis, the evidence from the
countries analysed in this study shows otherwise and prove that where the quality of trade
data applied are reliable and accurate, a country’s composition of imports has a considerable
and significant effect on the level and trend of the country’s imports cif/fob ratios. On the
other hand, where the data is unreliable, the resulting imports cif/fob ratios from the
computation are inaccurate and insignificant as an informative indicator of the country’s
actual international transportation costs. / Thesis (MBA)-University of KwaZulu-Natal, Westville, 2011.
