Abstract
The axiomatic property of consistency in aggregation is fundamental for example in the analysis of economic systems divided into sectors and sub-sectors, to ensure consistency of results at different levels of sectoral aggregation. The expenditure ratios index numbers satisfy this property by construction; however, they often do not satisfy other properties such as the factor reversibility. Martini’s index satisfies both properties and in this work it is applied to the problem of calculating the Total Factor Productivity (TFP), which typically refers to a context in which consistency in aggregation is important. In the proposed applications the results obtained are very encouraging and stimulate interest in further study.
