The empirical findings based on arithmetic and geometric commodity price indices are compared. When Grilli-Yang’s arithmetic mean index is employed, the findings regarding commodity price trends are inconclusive. A new geometric mean index, in contrast, yields results that are robust.</p>}, number={2}, journal={Estudios Económicos de El Colegio de México}, author={Cuddington, John T. and Wei, Hong}, year={1992}, month={Jul.}, pages={159–179} }
