Aggregation of Price Risk over Commodities: An Economic Index Number Approach

Barry T. Coyle

American Journal of Agricultural Economics, 2007, vol. 89, issue 4, 1085-1097

Abstract: This article extends the economic theory of index numbers to the aggregation of price risk over commodities in production. Superlative indexes of aggregate price risk are related to Tornqvist and Fisher—type output quantity indexes. An application to major crops in Manitoba illustrates the empirical importance of the analysis. Copyright 2007, Oxford University Press.
