In microeconomics, the expenditure function represents the minimum amount of expenditure needed to achieve a given level of utility, given a utility function and the prices of goods. Formally, if there is a utility function u {\displaystyle u} that describes preferences over n goods, the expenditure function e ( p , u ∗ ) {\displaystyle e(p,u ...
The expenditure approach is basically an output accounting method. It focuses on finding the total output of a nation by finding the total amount of money spent. This is acceptable to economists, because, like income, the total value of all goods is equal to the total amount of money spent on goods.
[The formula does not make clear over what the summation is done. P C = 1 n ⋅ ∑ p t p 0 {\displaystyle P_{C}={\frac {1}{n}}\cdot \sum {\frac {p_{t}}{p_{0}}}} On 17 August 2012 the BBC Radio 4 program More or Less [ 3 ] noted that the Carli index, used in part in the British retail price index , has a built-in bias towards recording ...
Formally, the expenditure function is defined as follows. Suppose the consumer has a utility function u {\displaystyle u} defined on L {\displaystyle L} commodities. Then the consumer's expenditure function gives the amount of money required to buy a package of commodities at given prices p {\displaystyle p} that give utility of at least u ∗ ...
A cost estimate is the approximation of the cost of a program, project, or operation.The cost estimate is the product of the cost estimating process. The cost estimate has a single total value and may have identifiable component values.
Zero-based budgeting (ZBB) is a budgeting method that requires all expenses to be justified and approved in each new budget period, typically each year. It was developed by Peter Pyhrr in the 1970s.
Formulas in the B column multiply values from the A column using relative references, and the formula in B4 uses the SUM() function to find the sum of values in the B1:B3 range. A formula identifies the calculation needed to place the result in the cell it is contained within. A cell containing a formula, therefore, has two display components ...
In the Keynesian cross diagram, the upward sloping blue line represents the aggregate expenditure for goods and services by all households and firms as a function of their income. The 45-degree line represents an aggregate supply curve which embodies the idea that, as long as the economy is operating at less than full employment, anything ...
