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 ...
Thus the left side gives GDP by the income method, and the right side gives GDP by the expenditure method. The GDP is given on the bottom line of both sides of the report. GDP must have the same value on both sides of the account. This is because income and expenditure are defined in a way that forces them to be equal (see accounting identity ...
Real GDP can be used to calculate the GDP growth rate, which indicates how much a country's production has increased (or decreased, if the growth rate is negative) compared to the previous year, typically expressed as percentage change. The economic growth can be expressed as real GDP growth rate or real GDP per capita growth rate.
A variety of measures of national income and output are used in economics to estimate total economic activity in a country or region, including gross domestic product (GDP), Gross national income (GNI), net national income (NNI), and adjusted national income (NNI adjusted for natural resource depletion – also called as NNI at factor cost).
GDP (Gross Domestic Product) is the value of all goods and services produced within a country during one year. GDP measures flows rather than stocks (example: the public deficit is a flow, measured per unit of time, while the government debt is a stock, an accumulation). GDP can be expressed equivalently in terms of production or the types of ...
Government spending or expenditure includes all government consumption, investment, and transfer payments. [1] [2] In national income accounting, the acquisition by governments of goods and services for current use, to directly satisfy the individual or collective needs of the community, is classed as government final consumption expenditure.
In macroeconomics, investment "consists of the additions to the nation's capital stock of buildings, equipment, software, and inventories during a year" [1] or, alternatively, investment spending — "spending on productive physical capital such as machinery and construction of buildings, and on changes to inventories — as part of total spending" on goods and services per year.
(Y − T + TR) is disposable income whereas (Y − T + TR − C) is private saving. Public saving, also known as the budget surplus, is the term (T − G − TR), which is government revenue through taxes, minus government expenditures on goods and services, minus transfers. Thus we have that private plus public saving equals investment.
