	Marginal Cost (Site not responding. Last check: 2007-10-20)
		In this case, of course, it is marginal cost.
		In the John Bates Clark style example we have been using, total cost is 280000 for an output of 3120, and it is 33000 for an output of 3625.
		for a marginal cost of $99.01 for the next unit produced.

	Marginal cost - Wikipedia, the free encyclopedia
		Mathematically, the marginal cost (MC) function is expressed as the derivative of the total cost (TC) function with respect to quantity (Q).
		Externalities are costs (or benefits) that are not borne by the parties to the economic transaction.
		Variable cost also known as, operating costs, prime costs, on costs and direct costs, are costs which vary directly with the level of output, for example, labour, fuel, power and cost of raw material.

	Economics Interactive Tutorial: Cost Concepts
		Marginal cost is the difference in total cost between one rate of output and another.
		Marginal cost on this graph is the difference in cost between the given output rate and the next lower one.
		The total cost curve bends down a bit for output rates from 0 to 4, because the marginal cost is falling.

	Marginal cost (Site not responding. Last check: 2007-10-20)
		In economics and finance, marginal cost is the increase in total cost that arises when the quantity produced (or purchased) increases by one unit.
		However, when one factors in opportunity cost, it is possible for the Marginal cost to increase with the total number of units produced.
		Variable cost also known as, operating costs, prime costs, on costs and direct costs, are costs which vary directly with the rate of output, for example, labour, fuel, power and cost of raw material.

		In economics and finance, marginal cost is the cost of increasing the quantity produced (or purchased) by one unit.
		For example, the marginal cost to go from producing 0 barrels of oil to producing 1 barrel of oil is tremendous.
		Marginal cost is not the same as average unit cost.

	The Environmental Literacy Council - Marginal Costs & Benefits
		Marginal cost is an important measurement because it accounts for increasing or decreasing costs of production, which allows a company to evaluate how much they actually pay to ‘produce’ one more unit.
		Marginal benefit is similar to marginal cost in that it is a measurement of the change in benefits over the change in quantity.
		Marginal costs and benefits are a vital part of economics because they help to provide the relevant measurement of costs and benefits at a certain level of production and consumption.

	Costs: a key concept in Economics
		For instance, the cost of renting an office is a fixed cost, since usually the contract fixes it for a certain period of time (say one year), without any reference to the income produced by the operations that take place in the same office.
		For instance, the labour costs can be fixed costs, quasi-fixed costs or variable costs depending on the legal contracts of employment and the rules governing wages.
		In the case of an exporter, an example of sunk costs could be the costs of analysing the market and of exploring opportunities and seeking commercial partners.

	Global Warming Policy: Some Economic Implications
		Following several previous studies, estimates of marginal cost are obtained through the use of a welfare-theoretic framework (a method for measuring the cost of deviating from market efficiency) built on top of a simulation model of world energy markets.
		The first marginal cost curve, shown in Figure II, represents the marginal costs to the world of the U.S. fossil fuel conservation necessary to reduce CO emissions.
		The marginal benefit of emission reduction would remain $2.86 per barrel of oil equivalent, but the marginal cost of compliance would rise to $20 to $25, depending on whether the United States is able to use offsets or credits.

	TCS Daily - Marginalized
		The axiom "prices must equal marginal cost" does not tell you whether the relevant time dimension is a decade, a year, or an hour, which makes it into a meaningless statement.
		So to set up an identity between marginal cost and price, without a tight specification of the assumptions about time, or to assume that short-term marginal cost is the ticket, produces nonsense.
		The cost of the extra fuel burned is less than this, and all other costs are, as of that frozen moment in time, fixed, so the airline would indeed make money by taking the deal.

		The private marginal cost of a commodity or service is the expense the producer incurs in making one more unit; the social marginal cost is the expense or damage to society as the consequence of producing that unit of product.
		These external costs and benefits, or externalities, spill over to other parties, and therefore are sometimes referred to as "spillover effects." For example, said Pigou, sparks from railway engines may do damage to surrounding woods or crops without their owners being compensated for the damage.
		According to Pigou the welfare task of government is to equalize (1) private and social marginal costs and (2) private and social marginal benefits.

	Marginal Benefits and Marginal Costs
		However, the idea that marginal benefit equals marginal costs at the social optimum, or efficient point, is one of the most important concepts economists bring to the table when discussing environmental issues.
		We haven’t discussed marginal damages and marginal costs, but the idea is that we want to minimize the sum of the total damages and the total costs.
		Marginal costs of pollution abatement are shown to be very low for high levels of pollution and therefore low levels of pollution abatement As pollution abatement gets larger and Q gets smaller, it becomes increasingly expensive for the company to abate pollution.

	Marginal Adjustment Costs and Tobin's q
		This gradualness is governed by increasing marginal costs which are, in turn, the reason for a falling marginal efficiency of investment (MEI) function.
		The standard marginal adjustment cost solution we are outlining in terms of sequences of periods here was initiated by Hayek (1941) and Lerner (1944, 1953) and formally incorporated in two forms in modern economics.
		Marginal adjustment costs is what permits us to reconcile the Neoclassical microeconomic theory of capital (Clark) with the macroeconomic theory of investment (Fisher).

		Notice that the marginal benefit from the second piece of pizza is 25 units, but the marginal benefit of the tenth piece is only 2 units.
		This is because the gains to society (measured by marginal benefits) exceed the costs to society (measured by marginal costs).
		For example, suppose the law mandates that the water in a town be cleaned to the point until the marginal costs to society exceed the marginal benefits.At this level, the water is still too dirty to swim in and children who drink from the water are exposed to lead poisoning.

	1997 Federal Highway Cost Allocation Study - Summary Report
		Marginal costs represent the added costs associated with an additional trip, and are particularly relevant for questions about prices that should be charged to improve economic efficiency.
		Marginal costs include costs of the additional trip to the highway user (e.g., added vehicle operating cost and travel time), costs to public agencies (added use-related 3R and maintenance costs) and external costs such as air pollution and congestion costs imposed on other motorists.
		Costs associated with an additional mile of travel on rural Interstate highways are negligible, but costs on urban Interstate highways may be high, particularly if that travel is during peak periods when traffic volumes are at their highest.

	Electricity Prices in a Competitive Environment
		Marginal costs are defined as the operations and maintenance (OandM) costs of the most expensive generating plant needed to supply the immediate demand for electricity (the marginal cost of generation).2 During periods of high demand, when demand approaches the limits of generating capacity, prices may rise above the marginal cost of generation.
		The marginal cost of generation and the reliability price adjustment are added to unit taxes (per kilowatthour) to estimate the competitive price for generation services.
		As a result, the costs of electricity production—and thus the marginal cost and competitive price—rise and fall with changes in the demand for power, as generating plants are dispatched or taken off line.

	Tutor2u - Marginal Costs of Production
		A change in marginal costs might come about for example because of a change in the prices of essential raw materials or an increase in the wage rate paid to part-time employees.
		The marginal cost of producing an extra unit is linked with the marginal productivity of labour.
		If marginal product is falling, assuming the cost of employing extra units of labour is constant, then the extra costs of the additional units of output will rise.

	BTS \| Estimation and Evaluation of Full Marginal Costs of Highway Transportation in New Jersey
		Marginal vehicle operating cost is estimated in terms of distance traveled, and this assumption cancels out insurance cost in the marginal cost formula since these are usually defined in terms of vehicle age.
		The marginal cost function is developed simply by multiplying the unit cost values of each pollutant (dollars/gram) by the increase in the amount of pollutant emitted due to a unit increase in the traffic volume.
		As stated in section 2, highway marginal cost pricing requires that every user be held responsible for the cost he or she imposes on the rest of the traffic with his or her additional trips.

	Marginal Analysis (Site not responding. Last check: 2007-10-20)
		The marginal benefit here would be the change in your benefits (better understanding of economics, better homework grade, increased G.P.A., etc.) that you would receive from an increase in your study time (an additional 20 minutes to read the next section).
		Each time, "marginal" simply means "a change." Economists say that when making a decision, people think at the margin, which simply means that they compare marginal costs with marginal benefits.

		Peak-season months are aggregated and the average on-peak marginal energy cost is calculated for the peak period; non-peak months are aggregated and the average on-peak marginal energy cost is calculated for the non-peak period.
		Similarly, the average on-peak marginal energy rate in the non-peak months is set at the average on-peak marginal energy costs in the off-peak months.
		The off-peak marginal rate is calculated as the average off-peak marginal costs over the 12-month period.

	Marginal Costs Versus Marginal Returns: Why Cutting Costs is Not Always... (Illini DairyNet)
		Assuming feed costs $6.56/cwt, and labor at $2.05/cwt, the cost to produce each additional cwt of milk is $8.61.
		Cost of feed to produce that milk is $45.92, and the cost of the bST would be $26.25, for a total of $72.17 in costs.
		Total cost to produce the additional 5 cwt of milk is $42.80 each day, value of the milk is $62.50, and marginal profit is $19.70/day.

		Marginal cost is the change in total cost resulting from an action.
		As long as the marginal benefit of an activity exceeds the marginal cost, people are better off doing more of it; when the marginal cost exceeds the marginal benefit, they are better off doing less of it.
		Apply the concepts of marginal benefit and marginal cost to an environmental policy to find the optimal amount of pollution for two firms that have substantially different costs of reducing pollution.

	First Monday: Differential Pricing and Efficiency (Site not responding. Last check: 2007-10-20)
		Second, "marginal willingness to pay" refers to the willingness to pay for an incremental unit of the good and "marginal cost" refers to the cost of providing an incremental unit of the good.
		Pricing at marginal cost may or may not be efficient: it depends on how the consumers' total willingness-to-pay relates to the total cost of providing the good.
		The requirement that the marginal user pay marginal cost is a strong one, especially in cases where the marginal cost of usage is close to zero.

	CEPE - PROJECTS, Marginal costs of enhanced energy efficiency measures (buildings)
		In the project, "Marginal Costs of Additional Energy Efficiency Measures in Residential Buildings" the costs and benefits of energy-efficient measures in residential buildings were empirically determined.
		The project goal is therefore to empirically determine the current level of the marginal and average costs of building envelope energy efficiency measures and of the optimisation of building technologies.
		Applying the experience curve approach, the potential future development of costs and technical parameters has to be estimated for the next 10 to 20 years.

	Cost Recovery Approach - 10 - How should charges be structured?
		long run marginal costs: The different between short and long run marginal costs is that changes to the costs of inputs that are generally regarded as fixed in the short term, such as capital, are taken into account when assessing avoidable or incremental costs at the margin.
		In light of the analysis of how operational costs are structured and what are the key cost drivers the options for structuring charges (refer Box 5 above) should be assessed against the objectives of cost recovery and other relevant considerations.
		Marginal cost pricing, provided central fixed costs are not overly large and likely to compromise full cost recovery, as this option relates costs directly to usage.

	XIII
		We have seen that net benefits are maximized where marginal benefits are equal to marginal costs as long as marginal costs "cut" marginal benefits from below. Profit is one type of net benefit, revenues net of costs, that is, revenues minus costs. Marginal benefits that we use here are called marginal revenues.
		What this means is that for profits to be maxmized at the quantity where marginal revenues and marginal costs are equal, marginal costs must be below marginal revenues prior to their equality.
		If this were not true, if marginal costs intersected marginal revenues from above, then all the units produced before the point where marginal revenues and marginal costs are equal must have added more to costs than to revenues.

	Online TDM Encyclopedia - Transportation Costs
		Costs and benefits have a mirror image relationship: a cost can be defined as a reduction in benefits and a benefit can be defined as a reduction in costs.
		For example, depreciation is often considered a fixed cost because car owners make the same payments no matter how many miles a year they drive, but a car’s operating life and resale value are affected by how much it is driven, so depreciation is partly variable over the long term.
		Motorists tend to perceive immediate costs such as travel time, stress, parking fees, fuel, and transit fares, while costs that are paid infrequently, such as insurance, depreciation, maintenance, repairs and residential parking, are often underestimated.
