The Marshall-Edgeworth index, credited to Marshall (1887) and Edgeworth (1925), [11] is a weighted relative of current period to base period sets of prices. This index uses the arithmetic average of the current and based period quantities for weighting. It is considered a pseudo-superlative formula and is symmetric. [12]
For example, a Törnqvist index summarizing labor input may weigh the growth rate of the hours of each group of workers by the share of labor compensation they receive. [7] The Törnqvist index is a superlative index, meaning it can approximate any smooth production or cost function. "Smooth" here means that small changes in relative prices for ...
Index numbers are used especially to compare business activity, the cost of living, and employment. They enable economists to reduce unwieldy business data into easily understood terms. In contrast to a cost-of-living index based on the true but unknown utility function, a superlative index number is an index number that can be calculated. [1]
The formula calculator concept can be applied to all types of calculator, including arithmetic, scientific, statistics, financial and conversion calculators. The calculation can be typed or pasted into an edit box of: A software package that runs on a computer, for example as a dialog box. An on-line formula calculator hosted on a web site.
Substitution bias describes a possible bias in economic index numbers if they do not incorporate data on consumer expenditures switching from relatively more expensive products to cheaper ones as prices changed. Substitution bias occurs when prices for items change relative to one another.
The new measure, called a "superlative" index, is designed to be a closer approximation to a "cost-of-living" index than the other measures. The use of expenditure data for both a base period and the current period in order to average price change across item categories distinguishes the C-CPI-U from the existing CPI measures, which use only a ...
The Malmquist Index (MI) is a bilateral index [a] that can be used to compare the production technology of two economies. It is named after Professor Sten Malmquist, on whose ideas it is based. It is also called the Malmquist Productivity Index. The MI is based on the concept of the production function. This is a function of maximum possible ...
In the last equation, is the market yield on the th asset, and is the yield available on a benchmark asset, held only to carry wealth between different time periods. In the literature on aggregation and index number theory, the Divisia approach to monetary aggregation, M t D {\displaystyle M_{t}^{D}} , is widely viewed as a viable and ...
