In microeconomics, economic efficiency, depending on the context, is usually one of the following two related concepts: [1] Allocative or Pareto efficiency : any changes made to assist one person would harm another.
[12] [18] [24] Second, even if increased efficiency does not reduce the total amount of fuel used, there remain other benefits associated with improved efficiency. For example, increased fuel efficiency may mitigate the price increases, shortages and disruptions in the global economy associated with crude oil depletion. [ 25 ]
For example, in the IS-LM graph shown here, the IS curve shows the amount of the dependent variable spending (Y) as a function of the independent variable the interest rate (i), while the LM curve shows the value of the dependent variable, the interest rate, that equilibrates the money market as a function of the independent variable income ...
The production function is central to the marginalist focus of neoclassical economics, its definition of efficiency as allocative efficiency, its analysis of how market prices can govern the achievement of allocative efficiency in a decentralized economy, and an analysis of the distribution of income, which attributes factor income to the ...
Figure 3: Production-possibilities frontier for an economy with two products illustrating Pareto efficiency Figure 4: Frontier points that violate allocative efficiency Production-Possibility Frontier delineates the maximum amount/quantities of outputs (goods/services) an economy can achieve, given fixed resources ( factors of production ) and ...
The income growth caused by increased production volume is determined by moving along the production function graph. The income growth corresponding to a shift of the production function is generated by the increase in productivity. The change of real income so signifies a move from the point 1 to the point 2 on the production function (above).
The differentiation between long-run and short-run economic models did not come into practice until 1890, with Alfred Marshall's publication of his work Principles of Economics. However, there is no hard and fast definition as to what is classified as "long" or "short" and mostly relies on the economic perspective being taken.
Consumption is an affine function of income, C = a + bY where the slope coefficient b is called the marginal propensity to consume. If any of the components of aggregate demand, a, I p or G rises, for a given level of income, Y , the aggregate demand curve shifts up and the intersection of the AD curve with the 45-degree line shifts right.
