Retrospective Computations of Price Index Numbers: Theory and Application
نویسندگان
چکیده
Due to outdated weighting information, a Laspeyres‐based consumer price index (CPI) is prone accumulating upward bias. Therefore, the present study introduces and examines simple transparent revision approaches that retrospectively address source of They provide consistent long‐run time series CPI require no additional information. Furthermore, coherent decomposition bias into contributions individual product groups developed. In case study, are applied CPI. The empirical results confirm theoretical predictions. proposed adoptable not only most national CPIs but also other price‐level measures such as producer or import export indices.

CREDIBILITY THEORY ORIENTED PREFERENCE INDEX FOR RANKING FUZZY NUMBERS
This paper suggests a novel approach for ranking the most applicable fuzzy numbers, i.e. $LR$-fuzzy numbers. Applying the $alpha$-optimistic values of a fuzzy number, a preference criterion is proposed for ranking fuzzy numbers using the Credibility index. The main properties of the proposed preference criterion are also studied. Moreover, the proposed method is applied for ranking fuzz...

متن کاملNumerical computations with infinite and infinitesimal numbers: Theory and applications
A new computational methodology for executing calculations with infinite and infinitesimal quantities is described in this chapter. It is based on the principle ‘The part is less than the whole’ introduced by Ancient Greeks and applied to all numbers (finite, infinite, and infinitesimal) and to all sets and processes (finite and infinite). It is shown that it becomes possible to write down fini...
