Marginal Concepts
In economics, marginal concepts are associated with a ''specific change'' in the quantity used of a good or service, as opposed to some notion of the over-all significance of that class of good or service, or of some total quantity thereof.{{citation needed, date=February 2012 Marginality Constraints are conceptualized as a ''border'' or ''margin''. Wicksteed, Philip Henry; ''The Common Sense of Political Economy'' (1910), Bk I Ch 2 and elsewhere. The location of the margin for any individual corresponds to his or her ''endowment'', broadly conceived to include opportunities. This endowment is determined by many things including physical laws (which constrain how forms of energy and matter may be transformed), accidents of nature (which determine the presence of natural resources), and the outcomes of past decisions made both by others and by the individual himself or herself. A value that holds true given particular constraints is a ''marginal'' value. A change that would ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Economics
Economics () is a behavioral science that studies the Production (economics), production, distribution (economics), distribution, and Consumption (economics), consumption of goods and services. Economics focuses on the behaviour and interactions of Agent (economics), economic agents and how economy, economies work. Microeconomics analyses what is viewed as basic elements within economy, economies, including individual agents and market (economics), markets, their interactions, and the outcomes of interactions. Individual agents may include, for example, households, firms, buyers, and sellers. Macroeconomics analyses economies as systems where production, distribution, consumption, savings, and Expenditure, investment expenditure interact; and the factors of production affecting them, such as: Labour (human activity), labour, Capital (economics), capital, Land (economics), land, and Entrepreneurship, enterprise, inflation, economic growth, and public policies that impact gloss ...

Opportunity Cost
In microeconomic theory, the opportunity cost of a choice is the value of the best alternative forgone where, given limited resources, a choice needs to be made between several mutually exclusive alternatives. Assuming the best choice is made, it is the "cost" incurred by not enjoying the ''benefit'' that would have been had if the second best available choice had been taken instead. The '' New Oxford American Dictionary'' defines it as "the loss of potential gain from other alternatives when one alternative is chosen". As a representation of the relationship between scarcity and choice, the objective of opportunity cost is to ensure efficient use of scarce resources. It incorporates all associated costs of a decision, both explicit and implicit. Thus, opportunity costs are not restricted to monetary or financial costs: the real cost of output forgone, lost time, pleasure, or any other benefit that provides utility should also be considered an opportunity cost.

Marginalism
Marginalism is a theory of economics that attempts to explain the discrepancy in the value of goods and services by reference to their secondary, or marginal, utility. It states that the reason why the price of diamonds is higher than that of water, for example, owes to the greater additional satisfaction of the diamonds over the water. Thus, while the water has greater total utility, the diamond has greater marginal utility. Although the central concept of marginalism is that of marginal utility, marginalists, following the lead of Alfred Marshall, drew upon the idea of Marginal product, marginal physical productivity in explanation of cost. The Neoclassical economics, neoclassical tradition that emerged from United Kingdom of Great Britain and Ireland, British marginalism abandoned the concept of utility and gave Marginal rate of substitution, marginal rates of substitution a more fundamental role in analysis. Marginalism is an integral part of mainstream economics, mainstream ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marginal Efficiency Of Capital
The marginal efficiency of capital (MEC) is that rate of discount which would equate the price of a fixed capital asset with its present discounted value of expected income. The term “marginal efficiency of capital” was introduced by John Maynard Keynes in his '' General Theory'', and defined as “the rate of discount which would make the present value of the series of annuities given by the returns expected from the capital asset during its life just equal its supply price”.Keynes, John Maynard; ''The General Theory of Employment, Interest, and Money'' (1936), p 135. The MEC is the net rate of return that is expected from the purchase of additional capital. It is calculated as the profit that a firm is expected to earn considering the cost of inputs and the depreciation of capital. It is influenced by expectations about future input costs and demand. The MEC and capital outlays are the elements that a firm takes into account when deciding about an investment project ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marginal Tax Rate
In a tax system, the tax rate is the ratio (usually expressed as a percentage) at which a business or person is taxed. The tax rate that is applied to an individual's or corporation's income is determined by tax laws of the country and can be influenced by many factors such as income level, type of income, and so on. There are several methods used to present a tax rate: statutory, average, marginal, flat, and effective. These rates can also be presented using different definitions applied to a tax base: inclusive and exclusive. Statutory A statutory tax rate is the legally imposed rate. An income tax could have multiple statutory rates for different income levels, where a sales tax may have a flat statutory rate. The statutory tax rate is expressed as a percentage and will always be higher than the effective tax rate. Average An average tax rate is the ratio of the total amount of taxes paid to the total tax base (taxable income or spending), expressed as a percentage. Averag ...

Marginal Propensity To Consume
In economics, the marginal propensity to consume (MPC) is a metric that quantifies induced consumption, the concept that the increase in personal consumer spending ( consumption) occurs with an increase in disposable income (income after taxes and transfers). The proportion of disposable income which individuals spend on consumption is known as propensity to consume. MPC is the proportion of additional income that an individual consumes. For example, if a household earns one extra dollar of disposable income, and the marginal propensity to consume is 0.65, then of that dollar, the household will spend 65 cents and save 35 cents. Obviously, the household cannot spend ''more'' than the extra dollar (without borrowing or using savings). If the extra money accessed by the individual gives more economic confidence, then the MPC of the individual may well exceed 1, as they may borrow or utilise savings. According to John Maynard Keynes, marginal propensity to consume is less than one. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marginal Propensity To Save
The marginal propensity to save (MPS) is the fraction of an increase in income that is not spent and instead used for saving. It is the slope of the line plotting saving against income. For example, if a household earns one extra dollar, and the marginal propensity to save is 0.35, then of that dollar, the household will spend 65 cents and save 35 cents. Likewise, it is the fractional decrease in saving that results from a decrease in income. The MPS plays a central role in Keynesian economics Keynesian economics ( ; sometimes Keynesianism, named after British economist John Maynard Keynes) are the various macroeconomics, macroeconomic theories and Economic model, models of how aggregate demand (total spending in the economy) strongl ... as it quantifies the saving-income relation, which is the flip side of the consumption-income relation, and according to Keynes it reflects the fundamental psychological law.

Marginal Product Of Capital
In economics, the marginal product of capital (MPK) is the additional production that a firm experiences when it adds an extra unit of input. It is a feature of the production function, alongside the labour input. Definition The marginal product of capital (MPK) is the additional output resulting, ceteris paribus ("all things being equal"), from the use of an additional unit of physical capital, such as machines or buildings used by businesses. The marginal product of capital (MPK) is the amount of extra output the firm gets from an extra unit of capital, holding the amount of labor constant: \mathit_K = F(K + 1, L) - F(K, L) Thus, the marginal product of capital is the difference between the amount of output produced with K + 1 units of capital and that produced with only K units of capital.N. Gregory Mankiw. (2010). Macroeconomics. United States: Worth Publishers Determining marginal product of capital is essential when a firm is debating on whether or not to invest on the a ...

Marginal Product Of Labor
In economics, the marginal product of labor (''MP''''L'') is the change in output that results from employing an added unit of labor. It is a feature of the production function and depends on the amounts of physical capital and labor already in use. Definition The marginal product of a factor of production is generally defined as the change in output resulting from a unit or infinitesimal change in the quantity of that factor used, holding all other input usages in the production process constant. The marginal product of labor is then the change in output (''Y'') per unit change in labor (''L''). In discrete terms the marginal product of labor is: : \frac . In continuous terms, the ''MPL'' is the first derivative of the production function: : \frac .Perloff, J., ''Microeconomics Theory and Applications with Calculus'', Pearson 2008. p. 173. Graphically, the ''MPL'' is the slope of the production function. Examples There is a factory which produces toys. When there are no w ...

Marginal Product
In economics and in particular neoclassical economics, the marginal product or marginal physical productivity of an input (factor of production) is the change in output resulting from employing one more unit of a particular input (for instance, the change in output when a firm's labor is increased from five to six units), assuming that the quantities of other inputs are kept constant. The marginal product of a given input can be expressed as: :MP = \frac where \Delta X is the change in the firm's use of the input (conventionally a one-unit change) and \Delta Y is the change in the quantity of output produced (resulting from the change in the input). Note that the quantity Y of the "product" is typically defined ignoring external costs and benefits. If the output and the input are infinitely divisible, so the marginal "units" are infinitesimal, the marginal product is the mathematical derivative of the production function with respect to that input. Suppose a firm's output ''Y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
