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]
The selection of the proper index to use depends on the industry in which it is applied. For example, while CE, M&S or IC Index are typically employed for chemical process industries, the ENR (Engineering News-Record) construction index is used for general industrial construction and takes in account the prices for fixed amounts of structural steel, cement, lumber and labor.
A cost-of-living index is a conceptual measurement goal, however, not a straightforward alternative to the CPI. A cost-of-living index would measure changes over time in the amount that consumers need to spend to reach a certain utility level or standard of living. Both the CPI and a cost-of-living index would reflect changes in the prices of ...
A price index (plural: "price indices" or "price indexes") is a normalized average (typically a weighted average) of price relatives for a given class of goods or services in a given region, during a given interval of time.
The importance of being able to quickly calculate MR is that the profit-maximizing condition for firms regardless of market structure is to produce where marginal revenue equals marginal cost (MC). To derive MC the first derivative of the total cost function is taken. For example, assume cost, C, equals 420 + 60Q + Q 2. then MC = 60 + 2Q. [11]
The cost breakdown analysis is even more effective when repeated constantly, so that changes in the respective shares in total costs of the various cost drivers can be tracked down. Over a five-year period, the share of expenses for tires might have risen from 5% to 8%, accompanied by a decrease of expenses for personnel from 35% to 32%, which ...
A producer price index (PPI) is a price index that measures the average changes in prices received by domestic producers for their output. Formerly known as the wholesale price index between 1902 and 1978, the index is made up of over 16,000 establishments providing approximately 64,000 price quotations that the U.S. Bureau of Labor Statistics (BLS) compiles each month to represent thousands ...
The level of activity is then measured in a subsequent year, and the percentage changes are weighted together by the costs in the base year to get an overall percentage change in output. The mathematics of the calculation are identical to those for calculating any index number, such as a price index .
