Aggregable Health Inequality Indices

SSRN Electronic Journal, 2016
An aggregable family of multidimensional concentration indices is characterized, in order to be consistent with a property of exogenous risk factors, i.e. health risks for which agents are not responsible for. The family of concentration indices (or achievement indices by duality) lies in the class of polynomial functions.

Aggregating sustainability indicators: Beyond the weighted sum

Journal of Environmental Management, 2012
Sustainability analysts and environmental decision makers often overcome the difficulty of interpreting comprehensive environmental profiles by aggregating the results using multi-criteria decision analysis (MCDA) methods. However, the wide variety of methodological approaches to weighting and aggregation introduces subjectivity and often uncertainty ...

Aggregate Price Indices, New Goods, and Generics

The Quarterly Journal of Economics, 1995
Summary: This paper examines the appropriate treatment in the cost-of-living index of the appearance of new varieties of old goods. Existing theory here applies to individual households. Thus, we first show in what sense Laspeyres and Paasche indices for groups of households can be considered approximations to theoretically desirable group indices and ...
