The reference value is common called a base year in economics. [3] A low base effect is the tendency of an absolute change from a low initial amount to be translated into a larger percentage change, while a high base effect would be the tendency of an absolute change from a high initial amount to be translated into a smaller percentage change ...
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]
An alternative is to take the base period for each time period to be the immediately preceding time period. This can be done with any of the above indices. Here is an example with the Laspeyres index, where t n {\displaystyle t_{n}} is the period for which we wish to calculate the index and t 0 {\displaystyle t_{0}} is a reference period that ...
In economics, a base period or reference period is a point in time used as a reference point for comparison with other periods. [1] [2] It is generally used as a benchmark for measuring financial or economic data. [3] Base periods typically provide a point of reference for economic studies, consumer demand, and unemployment benefit claims.

Baseline budgeting is an accounting method the United States Federal Government uses to develop a budget for future years. Baseline budgeting uses current spending levels as the "baseline" for establishing future funding requirements and assumes future budgets will equal the current budget times the inflation rate times the population growth rate.

Compound annual growth rate (CAGR) is a business, economics and investing term representing the mean annualized growth rate for compounding values over a given time period. [1] [2] CAGR smoothes the effect of volatility of periodic values that can render arithmetic means less meaningful. It is particularly useful to compare growth rates of ...
A base period price is the average price for an item in a specified time period used as a base for an index, such as 1910–14, 1957–59, 1967, 1977, or 1982. Time series of data are often deflated to a base period price. Such deflated time series are referred to as constant dollar values (versus nominal dollar values).
