| Diewert’s “superlative” index numbers, defined to be exact for second-order aggregator functions, unify index number theory with aggregation theory but have been difficult to identify. We present a new approach to finding elements of this class. This new approach, related to that advocated by Henri Theil, transforms candidate index numbers into growth rate form and explores convergence rates to the Divisia index. Because the Divisia index in continuous time is exact for any aggregator function, any discrete time index number that converges to the Divisia index and that has a third-order remainder term is superlative. |

| Domestic tobacco producers have faced increasing competition from imported tobacco since the late 1970s. Much of the debate has centered on the unknown quality of imported tobacco. This study provides a discussion and clarification of the concept of quality, and demonstrates a method of measuring the average quality of imported tobacco. The results show that since 1977, imported tobacco has been steadily decreasing in average quality and moving toward lower quality producing countries and types of tobacco. The reasons for this decline are discussed along with the policy implications. |
