Consumption is the act of using resources to satisfy current needs and wants. [1] It is seen in contrast to investing, which is spending for acquisition of future income. [2] Consumption is a major concept in economics and is also studied in many other social sciences. Different schools of economists define consumption differently.
Gross domestic product (GDP) is a monetary measure of the market value [2] of all the final goods and services produced and rendered in a specific time period by a country [3] or countries. [4] [5] [6] GDP is often used to measure the economic health of a country or region. [3]
Gross domestic product (GDP) is defined as "the value of all final goods and services produced in a country in 1 year". [3] Gross national product (GNP) is defined as "the market value of all goods and services produced in one year by labour and property supplied by the residents of a country." [4]
Intermediate goods or services used in production can be either changed in form (e.g. bulk sugar) or completely used up (e.g. electric power). Intermediate consumption (unlike fixed assets) is not normally classified in national accounts by type of good or service, because the accounts will show net output by sector of activity.
In economics, a production function gives the technological relation between quantities of physical inputs and quantities of output of goods. The production function is one of the key concepts of mainstream neoclassical theories, used to define marginal product and to distinguish allocative efficiency, a key focus of economics. One important ...
The basket is allowed to change with people's consumption and investment patterns. [2] Specifically, for the GDP deflator, the "basket" in each year is the set of all goods that were produced domestically, weighted by the market value of the total consumption of each good.
TFP is calculated by dividing output by the weighted geometric average of labour and capital input, with the standard weighting of 0.7 for labour and 0.3 for capital. [3] Total factor productivity is a measure of productive efficiency in that it measures how much output can be produced from a certain amount of inputs.
Similar (In fact, the same) models can be used to determine how firms in an economy determine the least-cost combination of factors of production to use when producing goods. When Price-consumption curves are used in this context, they are called price-factor curves [2] and are constructed with Isoquant curves and a line representing the ratio ...
