Simply put: Marginal cost/benefit | The Incidental Economist
Businesses and their customers constantly balance costs and benefits. Small Business»; Advertising & Marketing»; Business Value» Marginal costs and benefits determine when shopping or producing become too Cost/Benefit Analysis. economic factors such as resources, labour cost, market, capital, science and tec. This marginal benefit theory is used in micro economy to direct the profit making What is the difference between BLW marginal opportunities cost and total. Marginal costs and benefits are extremely important to producers when choosing to help you dig up the carrots, wash them, and drive them to the market. of relationship – as you increase your production, your marginal cost will go up ( how.
If you offer an extra service to customers, you want to price it so that your marginal benefits exceed the costs. This can get tricky: If the service is free, for example, you may benefit from enhanced customer loyalty, but they may use it so often that the cost is still too high.
Changes If you change marginal benefits or costs enough, decisions will also change. If you cut the cost of a customer's second or third coffee refill, that may convince the customer to spend more money.

As long as the benefit of selling cheaper refills outweighs your cost, you both win. If you find a new production technology that cuts the marginal cost of making more of your product, the marginal benefits of boosting production starts looking better. Social cost Of great importance in the theory of marginal cost is the distinction between the marginal private and social costs. The marginal private cost shows the cost associated to the firm in question.
It is the marginal private cost that is used by business decision makers in their profit maximization goals. Marginal social cost is similar to private cost in that it includes the cost of private enterprise but also any other cost or offsetting benefit to society to parties having no direct association with purchase or sale of the product.
It incorporates all negative and positive externalitiesof both production and consumption. Examples might include a social cost from air pollution affecting third parties or a social benefit from flu shots protecting others from infection.
Externalities are costs or benefits that are not borne by the parties to the economic transaction. A producer may, for example, pollute the environment, and others may bear those costs. A consumer may consume a good which produces benefits for society, such as education; because the individual does not receive all of the benefits, he may consume less than efficiency would suggest.
Alternatively, an individual may be a smoker or alcoholic and impose costs on others. In these cases, production or consumption of the good in question may differ from the optimum level. Negative externalities of production[ edit ] Negative Externalities of Production Much of the time, private and social costs do not diverge from one another, but at times social costs may be either greater or less than private costs.
When marginal social costs of production are greater than that of the private cost function, we see the occurrence of a negative externality of production. Productive processes that result in pollution are a textbook example of production that creates negative externalities. Such externalities are a result of firms externalizing their costs onto a third party in order to reduce their own total cost.
As a result of externalizing such costs, we see that members of society will be negatively affected by such behavior of the firm. Suppose, instead of thinking in intervals of whole hours, we think in terms of smaller intervals, say, of 12 minutes. Then each rectangle would be only one-fifth as wide as the rectangles we drew in Figure 6. Their areas would still equal the total benefit and total cost of study, and the sum of those areas would be closer to the area under the curves.

The smaller the interval we choose, the closer the areas under the marginal benefit and marginal cost curves will be to total benefit and total cost. For purposes of our model, we can imagine that the intervals are as small as we like.
Over a particular range of quantity, the area under a marginal benefit curve equals the total benefit of that quantity, and the area under the marginal cost curve equals the total cost of that quantity.
We have the usual downward- sloping marginal benefit curve and upward-sloping marginal cost curve. The marginal decision rule tells us to choose D hours studying economics, the quantity at which marginal benefit equals marginal cost at point C.
We know that the total benefit of study equals the area under the marginal benefit curve over the range from A to D hours of study, the area ABCD. Total cost equals the area under the marginal cost curve over the same range, or ACD.
The difference between total benefit and total cost equals the area between marginal benefit and marginal cost between A and D hours of study; it is the green-shaded triangle ABC. This difference is the net benefit of time spent studying economics.
Panel b of Figure 6. If an activity is carried out at a level less than the efficient level, then net benefits are forgone.
The loss in net benefits resulting from a failure to carry out an activity at the efficient level is called a deadweight loss. Maximum net benefits are found where the marginal benefit curve intersects the marginal cost curve at activity level D.
Using Marginal Benefit and Marginal Cost Curves to Find Net Benefits
Panel b shows that if the level of the activity is restricted to activity level E, net benefits are reduced from the light-green shaded triangle ABC in Panel a to the smaller area ABGF. The forgone net benefits, or deadweight loss, is given by the purple-shaded area FGC. If the activity level is increased from D to J, as shown in Panel cnet benefits declined by the deadweight loss measured by the area CHI.
Now suppose a person increases study time from D to J hours as shown in Panel c. The total benefit of increasing study time equals the area under the marginal benefit curve between D and J; it is DCIJ. The cost of increasing study time in economics from D hours to J hours exceeds the benefit.
This gives us a deadweight loss of CHI. Only by studying up to the point at which marginal benefit equals marginal cost do we achieve the maximum net benefit shown in Panel a. We can apply the marginal decision rule to the problem in Figure 6.
