Perhaps the most plausible option for the regulator is point F; that is, to set the price where AC crosses the demand curve at an output of 6 and a price of 6.5. This plan makes some sense at an intuitive level: let the natural monopoly charge enough to cover its average costs and earn a normal rate of profit, so that it can continue operating, but prevent the firm from raising prices and earning abnormally high monopoly profits, as it would at the monopoly choice A. Of course, determining this level of output and price with the political pressures, time constraints, and limited information of the real world is much harder than identifying the point on a graph. For more on the problems that can arise from a centrally determined price, see the discussion of price floors and price ceilings in Demand and Supply .

Cost-plus versus price cap regulation

Indeed, regulators of public utilities for many decades followed the general approach of attempting to choose a point like F in [link] . They calculated the average cost of production for the water or electricity companies, added in an amount for the normal rate of profit the firm should expect to earn, and set the price for consumers accordingly. This method was known as cost-plus regulation    .

Cost-plus regulation raises difficulties of its own. If producers are reimbursed for their costs, plus a bit more, then at a minimum, producers have less reason to be concerned with high costs—because they can just pass them along in higher prices. Worse, firms under cost-plus regulation even have an incentive to generate high costs by building huge factories or employing lots of staff, because what they can charge is linked to the costs they incur.

Thus, in the 1980s and 1990s, some regulators of public utilities began to use price cap regulation    , where the regulator sets a price that the firm can charge over the next few years. A common pattern was to require a price that declined slightly over time. If the firm can find ways of reducing its costs more quickly than the price caps, it can make a high level of profits. However, if the firm cannot keep up with the price caps or suffers bad luck in the market, it may suffer losses. A few years down the road, the regulators will then set a new series of price caps based on the firm’s performance.

Price cap regulation requires delicacy. It will not work if the price regulators set the price cap unrealistically low. It may not work if the market changes dramatically so that the firm is doomed to incurring losses no matter what it does—say, if energy prices rise dramatically on world markets, then the company selling natural gas or heating oil to homes may not be able to meet price caps that seemed reasonable a year or two ago. But if the regulators compare the prices with producers of the same good in other areas, they can, in effect, pressure a natural monopoly in one area to compete with the prices being charged in other areas. Moreover, the possibility of earning greater profits or experiencing losses—instead of having an average rate of profit locked in every year by cost-plus regulation—can provide the natural monopoly with incentives for efficiency and innovation.

With natural monopoly, market competition is unlikely to take root, so if consumers are not to suffer the high prices and restricted output of an unrestricted monopoly, government regulation will need to play a role. In attempting to design a system of price cap regulation with flexibility and incentive, government regulators do not have an easy task.

Key concepts and summary

In the case of a natural monopoly, market competition will not work well and so, rather than allowing an unregulated monopoly to raise price and reduce output, the government may wish to regulate price and/or output. Common examples of regulation are public utilities, the regulated firms that often provide electricity and water service.

Cost-plus regulation refers to government regulation of a firm which sets the price that a firm can charge over a period of time by looking at the firm’s accounting costs and then adding a normal rate of profit. Price cap regulation refers to government regulation of a firm where the government sets a price level several years in advance. In this case, the firm can either make high profits if it manages to produce at lower costs or sell a higher quantity than expected or suffer low profits or losses if costs are high or it sells less than expected.

what is demand curve
Gift
demand carve is a graphical representation of the relationship between the price of the or the service and the quantity demanded for a given period of time
Adamsvictor
Is the graphical representation of demand schedule. Also it has negative slope
Abubakary
The law of equilibrium is state that the quantity demand are equal to quantity supply.
Abubakary
sometimes demand exceeds supply or vice versa .In the first situation prices tend to rise therefore supply and demand meet the balance point called as equilibrium .
Furkan
the point of intersection mathematically but this is just an assumption that all other variables remain equal
Deleon
when there is excess supply and demand it means there is forces acting upon the equilibrium and prices should be decreased or increased appropriately
Deleon
The law of equilibrium states that ceteris paribus, at a certain two variables will be equal to each other.

The difference between cyclical unemployment and structural unemployment
Prince Reply
Cyclical unemployment .it has to do with an increase in the quantity of good demanded or there is over production which result in fall in prices. Industries will be affected it will now causes retrenchment of workers in the industries while structural unemployment arises as a result of slight change

The state of balance achieved by an end user of products that refers to the amount of goods and services they can purchase given their present level of income and the current level of prices. Consumer equilibrium allows a consumer to obtain the most satisfaction possible from their income.
Okwori
where is the calculations?
Nathan Reply
what are the two conditions for aconsumer to be in the equilibrium under the theory of consumer behaviour in
Sahr
Economic equilibrium is a condition or state in which economic forces are balanced. In effect, economic variables remain unchanged from their equilibrium values in the absence of external influences. Economic equilibrium may also be defined as the point at which supply equals demand for a product,

Rhaiymornd
a bit of explanation please its my first year doing Economics
Thembelani
rare, limited. economic agents eg You dube, the govt & the business entities wants to maximise their utility/satisfaction but because limited resource or scarcity of such resources they are unable to satisfy their needs.
ian
thank u Sir , l understand what you are saying now
Thembelani
limited resources; you wanna take the most benefits from the minimum resource.
DA
if u ar a fresher, eco has to 2 fundamental parts "micro & macro". micro(small) this is were the economc agents ar discussd, economc systms, dmand & supply, typs of market systms etc and the macro (big) part the elucidates the functns of central bank, typs of employmnt, functns of money & int trade.
ian
there is an old adage that says "a picture is worth a thousand words" economics is full of graphing so it requires on the side of the student to master the art of keeping information in form graphs.
ian
oky Sir
Thembelani
scarcity becomes the fundamental problem of economics because of limited resources, when we take an individual, he or she has many wants, thus unlimited wants but can never satisfy all but only few.
Rhaiymornd
now when we take a firm, a firm maybe willing to produce two or more product into the market but due to limited resources they only produce one. the same way if we take the government, he or she maybe willing to bring development either through infrastructures,
Rhaiymornd
that is when consumer decision making rule comes in
Olusegun
choice arises as a result of scarcity of resources
Olusegun
so if we look through, the individual, firm and government, their wants are unlimited but due limited resources, all of their wants cannot be satisfy. therefore scarcity can be term as limited in supply of resources. scarcity is not lack of resources but insufficient resources
Rhaiymornd
there is a marriage with the following; scarcity, factors of production, opportunity cost curve (occ) or (ppc, ppf, tc) production possibility curve productn possibility frontier transformation curve. The OCC, PPC, PPF & TC explains the decisions made by householders, firms & the govt.
ian
opportunity cost also arises as a result of firm willing to produce a particular commodity but resources use in satisfying or producing such output is limited
Olusegun
wat ar those decisions? the most important is WHY nations economise tht is if they hav abundancy of factors of productn eg land, labour & entreprise? now since all of us have unlimited needs against few resourcs PPC, PPF, TC, OCC walks in to make wise allocatn of resources.
ian
how do those decisions made? eg by economic agents; a. Household (You) - if u have R10 & wish to buy a book & a pen & realise that both commodities seĺl at the same price which of the two (2) can u buy (necesity) and which one can u forgo (not all tht important).
ian
b. firms - they allocat mo resourcs to all thoz commoditz tht they think will yield mo profit. c. Govt - if the govt SA was to come in yo area which 1 would u think they can consider first tht can benefit the majority & the minority. So instead of building football stadium they construct a hospital.
ian
if the SA govt had enough resources they would have built both the stadium and the hospital but because of scarce in terms of resources they had to forgo the construction the stadium to build a hospital which is necessary for the majority to benefit.
ian
Opportunity cost well broken down..
Andres
opportunity cost means the lose of other alternatives when the alternative is chosen
saad Reply
is the benefits that you loose by not selecting a certain alternative.
EDWINY
individual wants maybe unlimited, but means to satisfy them are limited there one has to forgo some alternative in order to acquire other alternative and it must according priority, that is when scale of preference set in for individuals to make choice
