The Fisher index of TFP then has an appealing property as an average of upper and lower bounds for theoretical indexes.
Finally, we can use [lambda] from equation (10) to define Fisher index contributions to aggregate labour inputs productivity change.
Targeting the Fisher index
formula, the ECPI is conceptually similar to the energy component of the BLS Chained CPI (C-CPI-U), which targets a Tornqvist formula.
A final Fisher index
was performed for cafeteria and laundry services.
In addition, the development of the Fisher index
for the price and volume variables incorporates the effect of procedures whose prices were cut and of procedures where prices were not cut to estimate the cumulative Medicare impact.
For example, to compute IP growth as an annually weighted Fisher index
for the second half of 1996 requires unit value added for 1996 and 1997.
This section examines some ATPI series, based on the Fisher index
formula, for several class-of-service and point-of-origin categories.
This paper uses the Fisher index
to construct market sector and industry productivity series to provide methodological continuity with Diewert and Lawrence (1999), who also used the Fisher index
when constructing productivity series for New Zealand.
The revised IP index is called an "annually weighted Fisher index
6) If relative price changes are small, and if they are trend divergences (that is, if relative prices do not move back and forth), then gradually shifting the weights in a chain Laspeyres system will approximate the measures provided by a Fisher index
2002), "A Multiplicative Decomposition of the Fisher Index
of Real GDP," manuscript.
Both the cost-of-living index and the Fisher index
correctly captured that changing expenditure pattern.
Using Equation 3, the Fisher index
from 1968 to 2003 is calculated using the geometric means of the Laspeyres and Paasche indexes.
In the second article, Harper, McMenamin, and Dyckman, add valuable context to the theoretical and logistical issues regarding the Fisher index
and Medicare physician reimbursement in general.
The NHCCI differs from both the PPI and BPI since it uses a Fisher index
methodology, which embodies the idea that, for a fixed market basket, changing relative prices will lead to changes in the relative quantities being purchased in the basket as entities make substitutions within an item category.
