In economics, an input–output model is a quantitative economic model that represents the interdependencies between different sectors of a national economy or different regional economies. [1] Wassily Leontief (1906–1999) is credited with developing this type of analysis and earned the Nobel Prize in Economics for his development of this model.
In economics, factors of production, resources, or inputs are what is used in the production process to produce output—that is, goods and services. The utilized amounts of the various inputs determine the quantity of output according to the relationship called the production function .
Direct material input (DMI) is a measure of the total material inputs into an economy and is calculated as the sum of domestic extraction (DE) and imports. The physical trade balance (PTB) is a measure of net-imports and is calculated as the difference between imports and exports. Reflecting that material and money flow in opposite directions ...
The area of economics that focuses on production is called production theory, and it is closely related to the consumption (or consumer) theory of economics. [ 2 ] The production process and output directly result from productively utilising the original inputs (or factors of production ). [ 3 ]
In economics the production set is a construct representing the possible inputs and outputs to a production process. A production vector represents a process as a vector containing an entry for every commodity in the economy. Outputs are represented by positive entries giving the quantities produced and inputs by negative entries giving the ...
Wire-grid Cobb–Douglas production surface with isoquants A two-input Cobb–Douglas production function with isoquants. In economics and econometrics, the Cobb–Douglas production function is a particular functional form of the production function, widely used to represent the technological relationship between the amounts of two or more inputs (particularly physical capital and labor) and ...
Articles relating to the economics of production, the process of combining various material inputs and immaterial inputs (plans, know-how) in order to make something for consumption (output). Production is the act of creating an output , a good or service which has value and contributes to the utility of individuals.
The economic value of physical outputs minus the economic value of physical inputs is the income generated by the production process. By keeping the prices fixed between two periods under review we get the income change generated by a change of the production function.
