Problems of operationalizing the concept of a cost-of-living index

calculate Fisher- and Tdrnqvist- price indices. As we need actual weighting
scheme informations for the Fisher- and Tdrnqvist- price index calculation,
we can only calculate index numbers for the three years with EVS data avail-
able. Table 8 and table 9 show, that not only the Laspeyres price index is
exceeding the two COLIs but also the Fisher- and Tdrnqvist- price index are
lying far above the two COLIs. These results are a strong drawback for the
superlative index approach.
